 LX3710'THE STATION DRILL HOLE, AN EQUALLY FAINT YELLOW TRIANGLE HAS
 LX3710'BEEN PAINTED.  DRILL HOLE SHOWS SIGNS OF WEATHERING, BUT STILL
 LX3710'USEABLE. A NEW WIDE CONCRETE HIGHWAY BRIDGE HAS REPLACED THE OLD
 LX3710'BRIDGE WHICH STILL IN ITS ORIGINAL POSITION, PASSABLE ON FOOT,
 LX3710'BUT THE ROADWAY NO LONGER LEADS ACROSS THE OLD BRIDGE.  NOW IT
 LX3710'CROSS THE NEW BRIDGE.  FROM THE WEST FACE OF THE WEST SIDE OF

 LX3710'TO WEST SIDEWALL OF THE NEW BRIDGE.  NEW ROAD CONSTRUCTION
 LX3710'AND GRADING FOR NEW BRIDGE HAVE DESTROYED B.M. 2.  R.M. 1 WAS
 LX3710'FOUND AS DESCRIBED IN 1953 AND STAMPED U.S. 13 NO 1.

 LX3710'SEE REPORT OF C.H.O. , 1/18/61, AT WHICH TIME I HAD DOUBTS OF MY
 LX3710'RECORDING OF THE DATE, 1917.  ALSO, THE DESCRIPTION SAID, STONE
 LX3710'IS FLAT.  I RECALLED THAT THE W PORTION OF STONE, ALTHOUGH FLAT,
 LX3710'IS LOWER THAN THE LARGER E PORTION OF STONE, WHICH IS ALSO
 LX3710'FLAT.  ON MY RETURN HOME, 1/18 I SUSPECTED POSSIBLE STORM DAMAGE
 LX3710'TO THE STONE.  HENCE, MY RETURN VISIT.
 LX3710'
 LX3710'ATTACHED SKETCH INDICATES THAT ALL IS WELL WITH NO.13, EXCEPT
 LX3710'AS REPORTED, 1/18, DRILL HOLE SHOWS SIGNS OF WEATHERING, BUT
 LX3710'STILL USEABLE.  THE FAINT YELLOW PAINT, NOTED 1/18, SEEMED
 LX3710'EVEN FAINTER TODAY, WITH A STRONG 4 P.M. SUNLIGHT.  CHECKED
 LX3710'DISTANCES FROM NO.13 TO R.M. NO.1, WHICH HAS AN ARROW (IT IS A

 LX3710'IN CENTER, AND STAMPED 1917 NO.3.
 LX3710'
 LX3710'IN MY 1/18 REPORT, I NOTED THAT NO. OF NO.1, APPEARED LIKE A
 LX3710'3, ON ITS SIDE.  IN TODAYS SUNLIGHT, THE NO. WAS EASILY
 LX3710'READ.  (NO RESEMBLANCE TO A 3).  BOTH I AND MY GLASSES ARE ALL
 LX3710'RIGHT BUT I CALL EM AS I SEE EM, WHEN I SEE EM.
 LX3710'
 LX3710'IM QUITE SURE R.M. NO. 2 IS GONE.  I NOTICED TODAY THAT THE NEW
 LX3710'CONCRETE BRIDGE IS SEVERAL FEET HIGHER IN ELEVATION THAN THE OLD
 LX3710'ROAD BRIDGE.  FILL AND GRADING HAVE EITHER COVERED OR DESTROYED
 LX3710'R.M. NO. 2.
 LX3710'
 LX3710'JUST TO BE SURE THAT E END JETTY STONE, TODAY, IS THE SAME ONE AS
 LX3710'IN 1933, I MEASURED IT--6 FT. BY 4-1/2 FT.  DRILL HOLE ONE FOOT
 LX3710'FROM THE WESTERLY EDGE.  THIS AGREES WITH MATTISONS 33
 LX3710'DESCRIPTION.  AS YOU CAN SEE, I WAS SUSPICIOUS OF POSSIBLE STORM
 LX3710'DAMAGE, BUT 13 HAS A CLEAN BILL OF HEALTH, AS FAR AS IM
 LX3710'CONCERNED.  I EVEN TALKED WITH LOCAL PEOPLE WHO TOLD ME THAT THE
 LX3710'E END OF THIS JETTY DOES NOT TAKE A BEATING FROM STRONG ELY
 LX3710'WINDS.

 LX3710'IMPROVEMENTS TO ROADS IN THIS VICINITY).
 LX3710'
 LX3710'WHILE HERE, 11/10/61, I ALSO CHECKED OLD R.M. 1 (STAMPED

 LX6026'DESCRIBED BY COAST AND GEODETIC SURVEY 1934 (GCM)
 LX6026'THIS STATION WAS ESTABLISHED BY THE CORPS OF ENGINEERS, UNITED
 LX6026'STATES ARMY IN 1909.  GO 2.3 MILES N ON ROUTE 9 FROM THE W
 LX6026'APPROACH TO THE EAST HADDAM BRIDGE.  TURN RIGHT INTO A PRIVATE
 LX6026'RIGHT-OF-WAY ACROSS THE RAILROAD TRACKS.  CONTINUE TO THE S
 LX6026'SHORE OF THE MOUTH OF MILL CREEK TO THE LAST OF A GROUP OF
 LX6026'COTTAGES.  FOLLOW THE SHORE LINE OF THE RIVER SOUTHERLY
 LX6026'AROUND THE BOULDER STREWN POINT FOR ABOUT 200 YARDS TO THE
 LX6026'FIRST LARGE SMOOTH BOULDER AT THE FOOT OF THE STEEP BANK.  THE
 LX6026'STATION IS ABOUT 1.3 METERS FROM THE RIVER FACE OF THE BOULDER
 LX6026'AND 0.5 METER FROM THE BANK.  THE BOULDER MEASURES 15 BY
 LX6026'8 FEET AND IS 4 FEET HIGH ON THE RIVER FACE.  STATION IS
 LX6026'MARKED BY A BRASS PLUG SET FLUSH WITH THE SURFACE OF THE
 LX6026'ROCK.  PLUG IS STAMPED U. S. 105 IN THE TOP.  ONE STANDARD
 LX6026'REFERENCE MARK WAS ESTABLISHED.  IT IS IN A POINTED BOULDER
 LX6026'DIRECTLY OFF-SHORE FROM THE STATION.  THERE ARE SEVERAL BOULDERS IN
 LX6026'THE RIVER AT THIS POINT.  THE REFERENCE MARK IS IN THE
 LX6026'LARGEST.  IT BEARS N 40 DEG E (MAGNETIC)

 LX3808'DESCRIBED BY COAST AND GEODETIC SURVEY 1882 (GB)
 LX3808'IN 1882 G. BRADFORD ESTABLISHED STATION BALD HILL 2 CLOSE TO
 LX3808'WHERE THE ORIGINAL STATION HAD BEEN, AND DETERMINING THE
 LX3808'LOCATION OF THE NEW STATION, WAS ABLE TO COMPUTE DISTANCE AND
 LX3808'DIRECTION OF BALD HILL AND RECOVER IT.  BALD HILL IS 4.07 FEET
 LX3808'N 38 DEG E FROM BALD HILL 2.  THE THREE ROCKS TO WHICH BALD HILL
 LX3808'WAS REFERENCED IN 1869 BY FARLEY WERE RECOVERED AND THE HOLES
 LX3808'AND ARROWS IN THEM DRILLED DEEPER.  FROM STATION BALD HILL 2 TO
 LX3808'SE ROCK IS 40 FEET, 11 INCHES.  TO NW ROCK IS 62 FEET, 6
 LX3808'INCHES.  AND TO NW ROCK, 47 FEET, 8 INCHES.  REPRODUCING
 LX3808'THESE DISTANCES THE EARTHEN ALE BOTTLE PLACED BY FARLEY WAS
 LX3808'RECOVERED, LYING ON ITS SIDE.  IT WAS REPLACED AT THE
 LX3808'INTERSECTION OF THE LINES FROM THE ROCKS (THEY INTERSECTED
 LX3808'WITHIN 1/2 INCH) IN AN UPRIGHT POSITION, ITS TOP 2 FEET, 4
 LX3808'INCHES BELOW THE SURFACE.  AROUND THE BOTTLE WERE
 LX3808'PLACED SMALL PEBBLES AND THE FRAGMENTS OF AN EARTHEN CONE
 LX3808'FOUND HERE.  ABOVE THE BOTTLE WAS PLACED A PINE STAKE 4- BY
 LX3808'4-INCHES IN SIZE, WITH BOTTOM A FEW INCHES ABOVE BOTTLE.
 LX3808'FOUR OTHER PINE STAKES, 4- BY 4-INCHES, WERE PLACED TO NE,
 LX3808'SE, SW AND NW OF STATION, COPPER TACKS IN THEIR HEADS BEING
 LX3808'6 FEET FROM THE STATION, AND LINES CONNECTING THEM DIAGONALLY
 LX3808'INTERSECT AT THE STATION.  (NOTE--BEFORE PUBLISHING THE
 LX3808'MEASURES TO BALD HILL AND BALD HILL 2, THE RELATIONSHIP
 LX3808'BETWEEN THE TWO STATIONS SHOULD BE PLOTTED AND TESTED FOR
 LX3808'CONSISTENCY.)

 LX3809'FOLLOWS--BOTTOM DIAMETER 1.25 FEET, TOP DIAMETER 0.7 FOOT, AND LENGTH
 LX3809'OF SIDE 1.11 FEET.  IT WAS BELIEVED BY FARLEY (WHO SEARCHED FOR AND
 LX3809'DID NOT FIND THE MARK IN 1868) AND BRADFORD (WHO RECOVERED THE CONE IN
 LX3809'1882-84) THAT THE ORIGINAL CONE HAD BEEN REMOVED BY E. BLUNT IN 1866
 LX3809'AND REPLACED WITH THE PRESENT CONE.  IT APPEARS FROM THE EVIDENCE
 LX3809'AVAILABLE THAT THIS BELIEF MAY HAVE BEEN BASED ON THE STATEMENT OF
 LX3809'NATIVES WHO CLAIMED THAT THEY SAW BLUNT DIG UP THE OLD CONE.  HOWEVER,
 LX3809'BLUNT MADE NO REPORT OF REMARKING THE STATION, AND SINCE THERE IS NO
 LX3809'INDICATION THAT EITHER FARLEY OR BRADFORD HAD THE ORIGINAL
 LX3809'DESCRIPTION, I AM INCLINED TO BELIEVE THAT THIS IS THE ORIGINAL CONE.

 LX4999'IN THE TOWN OF BOLTON, ON ABOUT THE HIGHEST POINT OF HILL.  MARKED BY
 LX4999'A DRILL HOLE AND COPPER BOLT IN ROCK.  THE ROCK ON WHICH THE STATION
 LX4999'STANDS CROPS OUT IN A RIDGE ABOUT 5 FEET IN WIDTH AND 40 OR 50 FEET IN
 LX4999'LENGTH.  ALL ROCK IN THE NEIGHBORHOOD IS COVERED WITH SOIL AND A
 LX4999'SCRUBBY GROWTH OF TREES.  ABOUT 60 FEET FROM THE STATION AND A LITTLE
 LX4999'TO THE LEFT OF THE LINE TO BALD HILL THERE IS QUITE A TALL WHITE PINE
 LX4999'TREE WITH POLE FASTENED IN IT.  IN 1875 THE STATION WAS VISITED AND A
 LX4999'TRIPOD SIGNAL ERECTED OVER IT.  A FEW DAYS LATER THE SIGNAL WAS PULLED
 LX4999'DOWN BY SOME EVILLY DISPOSED PERSON AND THE COPPER BOLT DUG FROM THE
 LX4999'ROCK WITH CHISEL OR PICK.  THE BOTTOM OF THE HOLE WAS STILL PLAINLY
 LX4999'MARKED, SO IT WAS ACCEPTED AS THE STATION, DRILLED DEEPER AND MOLTEN
 LX4999'LEAD POURED INTO IT.  THREE OTHER HOLES WERE DRILLED IN THE LEDGE,
 LX4999'EACH TWO FEET FROM THE STATION, FORMING AN EQUILATERAL TRIANGLE ABOUT
 LX4999'IT.  ONE OF THESE HOLES WAS TOWARD TALCOTT MOUNTAIN.  IN THE BOTTOM OF
 LX4999'IT WAS PLACED A PENNY OF DATE 1859.  IN THE HOLE TO THE NORTHWARD WAS
 LX4999'PLACED A PENNY OF 1873.  AND IN THE HOLE TO SOUTHWARD A PENNY OF 1860.
 LX4999'THE HOLES WERE THEN FILLED WITH MOLTEN LEAD.  THE HOLES WERE CONNECTED
 LX4999'WITH A CIRCLE DRILLED AROUND THE TRIANGULATION STATION AS A CENTER.
 LX4999'IN 1891 W.C. HODGKINS REPORTED THE STATION RECOVERED WITHOUT
 LX4999'DIFFICULTY, BUT THAT THE SURFACE MARKS HAD BEEN BADLY DEFACED BY
 LX4999'VISITORS.

 DH5825.NGS completed the third reprocessing of daily RINEX data from 1996 to 2022
 DH5825.for all stations in the NOAA CORS Network (NCN).  The reprocessed solution,
 DH5825.known as the Multi-Year CORS Solution 3 (MYCS3), is aligned with the
 DH5825.ITFR2020 global frame, epoch 2020.00.  The resulting MYCS3 coordinates
 DH5825.were then transformed to NAD83(2011/MA11/PA11), maintaining the currently
 DH5825.published epoch of 2010.00.

 LX3771
 LX3771'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1969 (CHO)
 LX3771'1/16/69, FOUND THE STATION AREA COVERED WITH 2 IN TO 3 IN OF
 LX3771'DEBRIS.  NOTHING HEAVY.  LIGHT STUFF, BUT COVERING NEARLY ALL OF THE
 LX3771'GRASS AREA ENCLOSED BY THE OVAL ROAD.  DEBRIS WAS MADE BY A BAD
 LX3771'STORM WITH UNUSUALLY HIGH TIDES AND STONG WINDS.  MY OPINION IS
 LX3771'THAT NONE OF THE DISKS HAS BEEN HARMED.  ILL TRY AGAIN, AFTER
 LX3771'THEIR MAINTENANCE MEN CLEAN UP THE MESS.
 LX3771'
 LX3771'DURING THE PAST FEW YEARS, A FEW NEW TREES HAVE BEEN PLANTED IN
 LX3771'THE OVAL AREA.

 LX3793'WHICH IS ONLY 15 INCHES DEEP), N, E, S, AND W (BY COMPASS) FROM
 LX3793'THE STATION, WITH MOUTHS DISTANT THEREFROM EACH 6 FEET.  LINES
 LX3793'CONNECTING OPPOSITE BOTTLES INTERSECT AT THE STATION.
 LX3793'THEY ARE GLASS GINGER ALE BOTTLES 9-1/2 INCHES LONG, AND
 LX3793'BLOWN IN THE GLASS ABOUT THE BOTTOM IS THE LEGEND--SEE THAT
 LX3793'EACH CORK IS BRANDED CANTRELL AND COCHRANE, DUBLIN AND
 LX3793'BELFAST.  MOUTHS OF BOTTLES POINT THE CENTER.  CROSSES WERE DRILLED
 LX3793'IN 4 ROCKS NOT FAR FROM THE STATION.  THE CROSSES ARE ABOUT 2
 LX3793'INCHES IN DIAMETER, WITH SMALL CONICAL HOLE IN CENTER.  ROCK 1
 LX3793'IS NEARLY LEVEL WITH SURFACE, ITS VISIBLE TOP BEING 24 BY 18
 LX3793'INCHES.  IT IS GRANITIC AND COVERED WITH LICHENS.  CROSS IS ON
 LX3793'HIGHEST PART OF ROCK, AND IS 20.26 FEET, N 25 DEG E FROM
 LX3793'STATION.  ROCK 2 IS OF BROWN SOFT STONE WITH QUARTZ VEIN OVER
 LX3793'IT.  IT IS ABOUT 1-1/2 FEET DIAMETER AND RISES ABOUT 6 INCHES
 LX3793'ABOVE GROUND, HIGHEST PART TO E.  CROSS IS IN NORTHWESTERN
 LX3793'SLOPE TOWARD STATION AND IS 13.42 FEET, S 35 DEG E THEREFROM.
 LX3793'ROCK 3 IS OF HARD BROWNISH AND WHITE STONE, 15 BY 24 INCHES
 LX3793'AND PROJECTING SOME 5 INCHES ABOVE GROUND.  IT IS RATHER
 LX3793'TRIANGULAR IN SHAPE AND THE CROSS IS ON THE EDGE OF TOP
 LX3793'TOWARD STATION.  IT IS 23.0 FEET, W 13 DEG S FROM STATION.
 LX3793'ROCK 4 IS OF HARD STONE SHOWING BROWN AND WHITE IN STREAKS.
 LX3793'IT IS 2-1/2 BY 3 FEET, PROJECTING ABOVE THE SURFACE ABOUT 1
 LX3793'FOOT.  IT IS GENERALLY ROUNDED AT THE EDGES, BUT PRESENTS ONE
 LX3793'PERPENDICULAR FACE ON ITS SOUTHERN SIDE TOWARD THE STATION.
 LX3793'ROCK IS ONE OF THE LARGEST IN THE STONE WALL ON N SIDE OF FIELD IN
 LX3793'WHICH STATION IS LOCATED, THE WAL IN THIS PART BEING SO
 LX3793'DILAPIDATED THAT ONLY A ROW OF STONES REMAIN.

 LX3774
 LX3774'DESCRIBED BY COAST AND GEODETIC SURVEY 1914 (PCW)
 LX3774'STATION IS ABOUT 25 FEET TO NORTHWESTWARD OF THE ORIGINAL
 LX3774'STATION OF THIS NAME.  STATION IS NEARLY ON SUMMIT OF A KNOLL AT
 LX3774'SOUTHEASTWARD END OF THE ISLAND AND THE HIGHEST LAND ON IT.  SE
 LX3774'PART OF KNOLL SHOWS AN ABRUPT FACE AS IT HAS BEEN WORN AWAY BY
 LX3774'THE SEA.  CENTER MARKED BY A GRANITE BLOCK 9 BY 9 INCHES ON TOP
 LX3774'AND 6 INCHES DEEP.  TOP IS DRESSED SQUARE AND CHANNELED, WITH
 LX3774'DRILL HOLE AT INTERSECTION OF CHANNELS.  UPPER SURFACE OF STONE
 LX3774'IS 2 FEET BELOW SURFACE OF GROUND.  ABOVE THE STONE IS A 4-BY
 LX3774'4-INCH SPRUCE STAKE, TOP JUST ABOVE SURFACE.  COPPER TACK IN
 LX3774'STAKE MARKS CENTER.  REFERENCE MARKS ARE AS FOLLOWS--ROCK,
 LX3774'BROWN, ABOUT 8 FEET IN DIAMETER AND 4 TO 5 FEET HIGH, WAS MARKED
 LX3774'ON ITS EASTERN SIDE WITH CROSS SOME 3 INCHES IN DIAMETER AND
 LX3774'2.2 FEET ABOVE GROUND.  STATION IS 24.4 FEET, E 20 DEG
 LX3774'S FROM CROSS.  A LOW ROCK NEARLY EVEN WITH SURFACE OF GROUND AND
 LX3774'ABOUT 2 FEET IN DIAMETER HAS A CROSS SIMILAR TO THE ONE DESCRIBED
 LX3774'ABOVE DRILLED IN ITS SUMMIT NEAR ITS NE SIDE.  STATION IS 31.45
 LX3774'FEET, N 34 DEG E BY COMPASS FROM CROSS.  A SIMILAR ROCK IS ABOUT 2
 LX3774'FEET DISTANT TO EASTWARD AND ANOTHER NORTHWESTWARD FROM THIS
 LX3774'ROCK.  FOUR BOTTLES WERE BURIED, 18 INCHES DEEP, N, E, S, AND W
 LX3774'(BY COMPASS) FROM THE STATION, WITH MOUTHS EACH 6 FEET THEREFROM.
 LX3774'LINES CONNECTING ALTERNATE BOTTLES INTERSECT AT THE STATION.  N
 LX3774'AND S BOTTLES ARE OF EARTHENWARE AND ABOUT 7 INCHES LONG.  E AND
 LX3774'W BOTTLES ARE GLASS BEER BOTTLES WITH LEGEND BLOWN IN
 LX3774'GLASS--THIS BOTTLE NOT TO BE SOLD.  THESE HAVE PATENT
 LX3774'STOPPERS.  FOUR STAKES OF 3-BY 4-INCH SPRUCE SCANTLING WERE SET
 LX3774'NE, SE, SW, AND NW (BY COMPASS) FROM STATION, COPPER TACKS IN
 LX3774'TOPS BEING 6 FEET THEREFROM.  LINES CONNECTING ALTERNATE TACKS
 LX3774'INTERSECT AT STATION.  IN 1908 THE STATION WAS RECOVERED.  THE
 LX3774'SUB-SURFACE MARK, 2 WITNESS ROCKS, AND 4 BOTTLES WERE ALL FOUND AS
 LX3774'DESCRIBED, IN GOOD CONDITION.  THE SURFACE MARK HAD BEEN REMOVED
 LX3774'TO MAKE ROOM FOR CENTER POLE OF LARGE 4-LEGGED SIGNAL OF THE
 LX3774'CONNECTICUT SHELL FISH COMMISSION WHICH WAS STANDING OVER THE
 LX3774'STATION.  NONE OF THE SPRUCE STAKES REMAIN.  IN 1914 THE
 LX3774'STATION WAS RECOVERED AS DESCRIBED IN 1908.

 LX3774'STATION WAS RECOVERED AS DESCRIBED WITH EXCEPTION OF SURFACE
 LX3774'REFERENCES.  NO ROCKS WITH CROSSES WERE LOCATED NOR WAS THERE A
 LX3774'SURFACE MARK FOR THE STATION.  THE CONNECTICUT SHELL FISH
 LX3774'COMMISSION STRUCTURE IS NOT EXACTLY OVER THE UNDERGROUND MARK
 LX3774'BUT THE CENTER POLE IS ABOUT 8 INCHES WESTERLY OF THE PROPER
 LX3774'PLACE.  THE SURFACE REFERENCE MARKS HAVE BEEN DISPLACED OR
 LX3774'DESTROYED, IN ALL PROBABILITY BY THE CRUMBLING AWAY OF THE
 LX3774'BLUFF LINE.

 LX3794                          STATION DESCRIPTION
 LX3794
 LX3794'DESCRIBED BY COAST AND GEODETIC SURVEY 1914 (PCW)
 LX3794'IN SOME OF THE DESCRIPTION BOOKS THERE IS A COPPS ISLAND 2, AND A
 LX3794'POSITION IS ALSO GIVEN FOR SUCH A NAMED STATION, WHICH IS VERY CLOSE
 LX3794'TO COPPS ISLAND.  IT SEEMS ALMOST CERTAIN THAT COPPS ISLAND AND COPPS
 LX3794'ISLAND 2 ARE IDENTICAL, AND THAT THE SLIGHT DIFFERENCE IN POSITION IS
 LX3794'DUE TO SCHEME OF ADJUSTMENT.  THE STATION ESTABLISHED IN 1834 WAS
 LX3794'RECOVERED IN 1882, THE REFERENCE MARKS BEING IDENTIFIED, DISTANCES
 LX3794'MEASURED AND UPON DIGGING THE CONE STATION MARK BEING RECOVERED.  CONE
 LX3794'WAS GLAZED EARTHENWARE, ABOUT 6 INCHES IN DIAMETER, BURIED LARGER END
 LX3794'UP, ABOUT 2.2 FEET BELOW SURFACE OF GROUND.  IT WAS RECOVERED IN 1904,
 LX3794'AND AGAIN IN 1908.  PROBABLY ALSO IN 1914, BUT THE DESCRIPTION OF THAT
 LX3794'DATE DOES NOT STATE THAT CONE WAS DUG FOR.  IN 1882 A WOODEN STUB WITH
 LX3794'TACK IN TOP WAS CENTERED IN THE CONE.  OVER THIS WAS PLACED A 4- BY
 LX3794'4-INCH SPRUCE POST REACHING NEARLY TO THE CONE AND EXTENDING A LITTLE
 LX3794'ABOVE THE GROUND.  REFERENCE MARKS PLACED THEN (1882) CONSISTED OF
 LX3794'FOUR 3- BY 3-INCH SPRUCE POSTS WITH TACKS IN TOP, PLACED TO THE SW,
 LX3794'NW, NE AND SE (BY COMPASS) FROM STATION.  THEY ARE 2 FEET UNDERGROUND,
 LX3794'AND MOUTHS POINTING THE STATION ARE EACH 6 FEET THEREFROM.  THE
 LX3794'NORTHERN BOTTLE IS A SMALL EARTHENWARE BOTTLE, BROKEN IN 3 PIECES.
 LX3794'THE SOUTHERN BOTTLE IS SIMILAR TO THE NORTHERN ONE, BUT IS WHOLE.
 LX3794'EASTERN AND WESTERN BOTTLES ARE OF GLASS AND HAVE PATENT CORKS.  BLOWN
 LX3794'IN GLASS IS THE LEGEND--THIS BOTTLE MUST NOT BE SOLD.  THE LARGE ROUND
 LX3794'ROCK OF THE ORIGINAL DESCRIPTION WAS MARKED WITH A CROSS DRILLED ON
 LX3794'ITS SUMMIT.  THIS CROSS IS ABOUT 4 INCHES LONG E AND W, AND 2 INCHES N
 LX3794'AND S.  IN CENTER OF CROSS IS DRILLED A HOLE.  ROCK IS ABOUT 2 1/2
 LX3794'FEET IN DIAMETER AND PROJECTS ABOUT 14 INCHES ABOVE GROUND.  IT IS
 LX3794'BROWN WITH WHITE MOTTLINGS OF QUARTZ.  THE CROSS IS 37.44 FEET S (BY
 LX3794'COMPASS) FROM THE STATION.  THE LARGE TRIANGULAR ROCK IN WALL, (ALSO
 LX3794'AN ORIGINAL REFERENCE MARK), WAS MARKED WITH A CROSS 2 INCHES LONG AT
 LX3794'CENTER OF WHICH A HOLE WAS DRILLED.  THE ROCK IS ABOUT 2 FEET IN
 LX3794'DIAMETER AND ABOUT 1 FOOT ABOVE GROUND, AND PROJECTS FROM WALL.  ROCK
 LX3794'IS WHITEY BROWN IN COLOR.  CROSS IS 45.97 FEET, W 26 DEG S (BY
 LX3794'COMPASS) FROM STATION.  A THIRD ROCK WAS MARKED (IN 1882) WITH A CROSS
 LX3794'ABOUT 2 INCHES IN SIZE WITH DRILL HOLE AT CENTER.  THIS ROCK IS BROWN
 LX3794'AND WHITE, ABOUT 2 FEET IN DIAMETER, AND RISES ONLY A FEW INCHES ABOVE
 LX3794'THE GROUND.  THE CROSS IS IN THE APPROXIMATE CENTER OF THE STONE, AND
 LX3794'IS 34.81 FEET, E 5 DEG N (BY COMPASS) FROM THE STATION.
 LX3794'
 LX3794'IN 1908 CONE AND REFERENCE CROSSES ON ROCKS FOUND IN GOOD CONDITION.

 LX3794'IN 1908 CONE AND REFERENCE CROSSES ON ROCKS FOUND IN GOOD CONDITION.
 LX3794'THE 4 BOTTLES PLACED IN 1882 ALSO FOUND UNDISTURBED.  A LARGE SIGNAL
 LX3794'PLACED OVER THE STATION BY THE SHELL FISH COMMISSION OF CONNECTICUT
 LX3794'WAS REPORTED OVER THE STATION IN 1904, IN 1908, AND AGAIN IN 1914,
 LX3794'WHEN THE STATION WAS REPORTED RECOVERED AS DESCRIBED.

 LX3700                          STATION DESCRIPTION
 LX3700
 LX3700'DESCRIBED BY COAST AND GEODETIC SURVEY 1934 (GCM)
 LX3700'LOCATED IN THE TOWN OF MILFORD ON THE E BANK OF THE HOUSATONIC RIVER
 LX3700'IS THE DEVON PLANT OF THE CONNECTICUT LIGHT AND POWER COMPANY WITH
 LX3700'TWIN BLACK SMOKE STACKS.  THEY ARE MADE OF SHEET STEEL.  A LADDER GOES
 LX3700'UP THE SIDE OF EACH.  THERE IS ALSO A SMALL PLATFORM AROUND THE TOP OF
 LX3700'EACH AND THEY STAND ABOUT 400 FEET ABOVE THE GROUND AND ARE 8 FEET IN
 LX3700'DIAMETER.  THEY ARE JUST NORTH OF THE NEW YORK, NEW HAVEN AND HARTFORD
 LX3700'RAILROAD BRIDGE.  FROM THE STRATFORD POINT LIGHTHOUSE ONE STACK ALMOST
 LX3700'COMPLETELY HIDES THE OTHER NEAR ENOUGH TO BE CALLED ON RANGE AND IT IS
 LX3700'IMPOSSIBLE TO TELL WHICH IS WHICH.
 LX3700
 LX3700                          STATION RECOVERY (1958)
 LX3700
 LX3700'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1958 (HEF)
 LX3700'TWO STACKS WERE SEEN FROM WELCHS POINT.  THE MOST SOUTHERLY STACK
 LX3700'WAS OBSERVED BUT FAILED TO CHECK THE 1932 STATION.  OBSERVATION
 LX3700'INDICATED THE STACK TO BE SOUTH OF THE 1932 STATION.  NO LADDER
 LX3700'WAS VISIBLE ON THIS STACK, HOWEVER ONE WAS SEEN ON THE MORE
 LX3700'NORTHERLY STACK.  IT IS POSSIBLE NORTH STACK 1932 HAS BEEN
 LX3700'DESTROYED.  IT IS RECOMMENDED THESE STACKS BE USED WITH CAUTION.
 LX3700

 LX3700
 LX3700'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1961 (CHO)
 LX3700'RECOVERED IN GOOD CONDITION, ESSENTIALLY AS DESCRIBED.  STACK IS MADE
 LX3700'OF STEEL, NOW PAINTED A SMOKY YELLOW.
 LX3700'
 LX3700'THE PHRASE, TWIN .SMOKE STACKS, STILL APPLIES, BUT THIS OLD STACK,
 LX3700'ERECTED IN 1924, IS NOW THE NORTHERN ONE OF TWO TALL TWINS.  THE
 LX3700'PRESENT, S N, EQUALLY TALL, STACK IS THE NEWEST OF THIS GROUP OF SIX
 LX3700'STACKS.
 LX3700'
 LX3700'SOUNDS A BIT CONFUSING, SO IVE MADE A SKETCH, COVERING ALL THIS.  I
 LX3700'KNOW I WAS THOROUGHLY CONFUSED, UNTIL MR. BURKE, PERSONNEL MGR.  AT
 LX3700'THE PLANT, EXPLAINED DETAILS TO ME.  ID ESTIMATE THAT THE PRESENT
 LX3700'SOUTHERNMOST STACK (THE NEWEST IN A GROUP OF SIX), IS ABOUT THE SAME
 LX3700'DISTANCE SOUTH OF OLD SOUTH AS OLD NORTH WAS NORTH OF OLD SOUTH.  MR.
 LX3700'BURKE GAVE ME THE FIGURE, 340 FT. ABOVE M.S.L., WHICH APPLIES TO THE
 LX3700'PRESENT TWO TALLER SOUTHERN STACKS.  THE 4 SMALLER STACKS TO THE N ARE
 LX3700'ABOUT 225 FT. HIGH.
 LX3700'
 LX3700'AT THE PLANT, BURKE DOES NOT HAVE LAT. OR LONG., NOR PLANE
 LX3700'COORDINATES.  I WOULD ASSUME THAT CONSTRUCTION ENGINEERS FOR THE CONN.
 LX3700'POWER AND LIGHT CO. DO HAVE THIS INFORMATION.  ILL TRY TO GET IT.

 LX3700'
 LX3700'ATTACHED SKETCH AND TWO REPORTS NOTED ABOVE, GIVE THE ESSENTIAL FACTS
 LX3700'ON C.P. AND L. PLANT AT DEVON, CONN. FOR CLARITY, IVE NUMBERED THE
 LX3700'STACKS, IN THEIR ORDER, GOING NORTH FROM THE BRIDGE.  THESE NUMBERS
 LX3700'ARE NOT PAINTED ON THE STACKS.
 LX3700'
 LX3700'I HOPE TO GET LAT. AND LONG. OF ALL SIX STACKS FROM THE POWER COMPANYS
 LX3700'CONSTRUCTION ENGINEERS.  IF UNAVAILABLE, I CAN LOCATE THEM.  HOWEVER.
 LX3700'IT IS MY OPINION THAT ONLY THE TWO TALLER STACKS (OLD S, AND NEW S)
 LX3700'BE SHOWN ON CHART 219.  THE FOUR SMALLER STACKS TO THE N, MIGHT BE
 LX3700'SHOWN IN SMALL CIRCLES, IF THIS DOES NOT CLUTTER UP THE GENERAL
 LX3700'APPEARANCE OF 219.
 LX3700'
 LX3700'OF COURSE, THE CGS HAS LAT. AND LONG. OF THE OLD S STACK.
 LX3700'
 LX3700'STACKS ARE NOT IN LINE WITH EACH OTHER.  ONLY APPROX. IN LINE.

 LX6116'THIS STATION IS ON THE STONE DUMP OF THE OLD ARNOLD QUARRY
 LX6116'ON THE NORTHERLY SIDE OF GREAT HILL.  IT IS NOW THE PROPERTY
 LX6116'OF E.E. DICKINSON.  THE TOP OF THE DUMP HAS BEEN LEVELED OFF
 LX6116'AND IS OCCUPIED BY A SMALL ONE-STORY COTTAGE.  THE STATION
 LX6116'IS 15.6 METERS WESTERLY OF THE NW CORNER OF THE COTTAGE AND
 LX6116'3.5 METERS FROM THE FACE OF THE DUMP.
 LX6116'
 LX6116'SURFACE, UNDERGROUND, AND REFERENCE MARKS ARE STANDARD BRONZE
 LX6116'DISKS SET IN CONCRETE AS DESCRIBED IN NOTES 1A, 7A, AND 11A.
 LX6116'
 LX6116'REFERENCE MARK NO.1 IS NEAR THE SOUTHERLY EDGE OF THE
 LX6116'LEVELED AREA.  IT BEARS S 15 DEG E (MAGNETIC).  REFERENCE MARK
 LX6116'NO.2 IS 5 METERS FROM THE NORTHERLY FACE OF THE DUMP AND
 LX6116'18 METERS FROM ITS WESTERLY EXTREMITY.  IT BEARS S 75 DEG W
 LX6116'(MAGNETIC).
 LX6116'
 LX6116'THE WITNESS MARK IS A SHALLOW DRILL HOLE IN THE W SIDE OF THE

 LX6116'
 LX6116'THIS STATION IS TO BE DESTROYED SOMETIME THIS SUMMER BY
 LX6116'LAND OWNER (LYLE H. BROOKS, ROUTE 9-A TYLERVILLE,
 LX6116'(HADDAM) CONN.).  MR. BROOKS SAID HE WAS GOING TO LOWER THE AREA BY
 LX6116'ABOUT 30 TO 50 FEET.  HE HAD NO OBJECTION TO THE REPLACING OF
 LX6116'THE STATION IN THE SAME HORIZONAL POSITION OR IN THE NEARBY AREA.
 LX6116'
 LX6116'IT APPEARS THAT BECAUSE OF THE ABUNDANCE OF CONTROL IN THE AREA,
 LX6116'THIS STATION COULD JUST BE ABANDONED.  IF IT WERE REPLACED IN THE
 LX6116'SAME HORIZONAL POSITION IT WOULD HAVE VIRTUALLY NO VISIBILITY
 LX6116'WITHOUT SOME SORT OF A TOWER.

 LX6858'
 LX6858'THE CHURCH IS A WHITE WOODEN BUILDING WITH A GABLE FACING N AND S.
 LX6858'
 LX6858'THE SPIRE IS AT THE NW CORNER OF THE MAIN AUDITORIUM.  THE
 LX6858'FOUR BELFRY OPENINGS ARE ON A LEVEL WITH THE RIDGE POLE OF
 LX6858'THE CHURCH.  THE OPENINGS ARE NOT SCREENED AND DIRECTLY ABOVE
 LX6858'EACH ONE, AN ORNAMENTAL GABLE IS SECURED TO THE SPIRE.  THE
 LX6858'SPIRE IS CONSIDERABLY MORE BULKY THAN THE GENERAL RUN.  IT HAS
 LX6858'WHITE SHINGLED SIDES WITH SOME ORNAMENTATION JUST BELOW THE
 LX6858'APEX.  AT THE APEX IS A TALL GOLDEN CROSS.
 LX6858'
 LX6858'CENTER IS THE VERTICAL MEMBER OF THE CROSS.

 LX6451'DESCRIBED BY COAST AND GEODETIC SURVEY 1910 (HPR)
 LX6451'IN EAST HAVEN, AT CORNER OF MAIN STREET AND THOMSON AVENUE.  THIS
 LX6451'CHURCH WAS ERECTED IN 1774, AND IS SAID TO BE ONE OF THE OLDEST
 LX6451'MEETING HOUSES IN THE STATE, AND THE OLDEST STONE MEETING HOUSE
 LX6451'STANDING IN ALL NEW ENGLAND.  ITS WALLS TODAY ARE AS FIRM AS WHEN
 LX6451'ERECTED, AND WILL PROBABLY STAND A CENTURY LONGER.
 LX6451'
 LX6451'IT WAS FULLY COMPLETED IN 1796 AND SPIRE ADDED.  GREAT TORNADO OF
 LX6451'OCTOBER 8, 1797, THREW DOWN THE SPIRE AND UNROOFED THE HOUSE.  IT WAS
 LX6451'AT ONCE REPAIRED.  IN 1798 BELL WAS INSTALLED.  IN 1859 THE STEEPLE
 LX6451'WAS REBUILT, THOUGH PROBABLY NOT CHANGED IN POSITION.  TOP OF THE
 LX6451'STEEPLE IS 196 FEET FROM GROUND.  RECOVERED IN 1916.

 LX6523'IN 1910 REPORTED THAT EAST ROCK PARK IN WHICH STATION WAS LOCATED
 LX6523'MIGHT BE REACHED BY EITHER THE STATE STREET OR WHITNEY AVENUE TROLLEY
 LX6523'LINES.  GRADED FOOTPATHS AND A ROAD FOR VEHICLES (AUTOMOBILES EXCEPTED
 LX6523'- 1910) LEAD TO THE STATION.  STATION MARKED BY A 4-INCH IRON BOLT SET
 LX6523'IN SULPHUR IN A DRILL HOLE IN THE ROCK.  STATION IS ABOUT 20.3 FEET N
 LX6523'OF LARGE FLAGPOLE IN PARK.  IT IS SURROUNDED BY BUSHES WHICH MAY
 LX6523'PREVENT ITS USE AS A STATION.  A CEDAR TREE IS 26.5 FEET FROM STATION,
 LX6523'17 DEG 45 MIN TO LEFT OF LINE TO NEW HAVEN LIGHTHOUSE.  A CHERRY TREE
 LX6523'IS 139.5 FEET FROM STATION, 110 DEG 31 MIN TO LEFT OF LINE TO
 LX6523'LIGHTHOUSE.
 LX6523'
 LX6523'IN 1910 CENTER BOLT FOUND IN GOOD CONDITION, LIKEWISE THE LARGE
 LX6523'FLAGPOLE MENTIONED IN 1904.  THREE IRON STRAPS LEADED INTO THE ROCK
 LX6523'AND TO WHICH THE LEGS OR BRACES OF SOME FORMER SIGNAL WERE SECURED

 LX6523'RIGHT ON PARK DRIVE, GO 0.4 MILE TO FOOT OF DRIVE LEADING TO SUMMIT.
 LX6523'TURN LEFT AND GO 1.7 MILES TO THE LOCATION OF THE STATION.  THE DRIVE
 LX6523'IS AT THE EDGE OF THE VERTICAL CLIFF AT THIS POINT.
 LX6523'
 LX6523'THE STATION IS NOT ON THE HIGHEST PART OF THE ROCK, BUT IS
 LX6523'APPROXIMATELY 0.2 MILE NW OF SOLDIERS AND SAILORS MONUMENT, WHICH
 LX6523'OCCUPIES THE SUMMIT.  THE STATION IS ALMOST DIRECTLY IN LINE WITH THE
 LX6523'AXIS OF ORANGE STREET.  THE DRIVE IS GUARDED WITH A LOW MASONRY WALL
 LX6523'WITH PIPE RAILING SUPPORTED BY CAST-IRON STANCHIONS.  THE MIDDLE OF
 LX6523'THIS RAIL BEARS S 68 DEG W (MAGNETIC) AND IS 13.1 METERS DISTANT.  A
 LX6523'20-FOOT HIGH STEEL STANDPIPE FOR PARK WATER SUPPLY BEARS S 85 DEG E
 LX6523'(MAGNETIC) DISTANT 32.6 METERS.  THE STUMP OF THE OLD 16-INCH FLAGPOLE
 LX6523'BEARS S 10 DEG E (MAGNETIC) AND IS 6.15 METERS DISTANT.
 LX6523'
 LX6523'THE STATION IS MARKED BY AN IRON BOLT, SET IN SULPHUR, FLUSH WITH THE
 LX6523'SURFACE OF AN OUTCROPPING LEDGE.  SEVERAL ANCHOR BOLTS ARE ALSO
 LX6523'SECURED IN THE ROCK IN THE VICINITY, BUT THEY PROJECT ABOVE THE ROCK
 LX6523'AND HAVE HOLES FOR FASTENING GUYS.
 LX6523'
 LX6523'REFERENCE MARK NO.1 IS SAME LEDGE AS STATION AND IS DESIGNED TO
 LX6523'DISTINGUISH THE CENTER BOLT FROM THE OTHERS.  IT BEARS S 73 DEG W
 LX6523'(MAGNETIC) AND IS 0.75 METER DISTANT.
 LX6523'
 LX6523'REFERENCE MARK NO.2 IS IN A SEPARATE OUTCROPPING AND BEARS S 41 DEG E
 LX6523'(MAGNETIC) DISTANT 10.28 METERS.  IT BEARS N 37 DEG E (MAGNETIC) FROM
 LX6523'THE MASONRY POST AT E END OF GUARD RAIL AND IS 14 METERS DISTANT.

 LX5251
 LX5251'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1943 (FN)
 LX5251'STATION WAS RECOVERED AS DESCRIBED, AND THE STATION MARK WAS
 LX5251'FOUND IN GOOD CONDITION.  THE REFERENCE MARKS WERE NOT RECOVERED,
 LX5251'AND, THEREFORE, TWO NEW REFERENCE MARKS WERE ESTABLISHED AT THIS
 LX5251'TIME.  NEW DESCRIPTION FOLLOWS--
 LX5251'
 LX5251'STATION IS LOCATED ON THE EXTREME S PART OF GOSHEN POINT, AND
 LX5251'IS ON THE ESTATE OF E.S. HARKNESS.  IT IS JUST S OF A 9-HOLE GOLF
 LX5251'COURSE, AND ABOUT 20 FT. S OF THE SEAWALL.  THE STATION MARK
 LX5251'IS STAMPED GOSHEN 1934 AND IS SET IN A DRILL HOLE IN THE TOP
 LX5251'OF A LARGE BOULDER THAT IS CUT OFF FROM THE MAINLAND AT HIGH
 LX5251'WATER.  THE TOP OF THE BOULDER IS ABOUT 1 M. ABOVE THE HIGH
 LX5251'WATERMARK.
 LX5251'
 LX5251'REFERENCE MARK 3 IS E-NE OF THE STATION, AND IS 3.5 FT.
 LX5251'S OF THE SEAWALL.  IT IS STAMPED GOSHEN NO 3 1943 AND PROJECTS
 LX5251'ABOUT 8 IN.
 LX5251'
 LX5251'REFERENCE MARK 4 IS NW OF THE STATION.  IT IS A BRONZE REFERENCE
 LX5251'DISK, STAMPED GOSHEN NO 4 1943 AND IS SET IN A DRILL HOLE IN A
 LX5251'LARGE MASS OF CONCRETE ON TOP OF THE SEAWALL.
 LX5251'
 LX5251'TO REACH THE STATION FROM THE INTERSECTION OF STATE HIGHWAY 156
 LX5251'AND THE PLEASANT BEACH ROAD WHICH IS ABOUT 3 MI. SW OF NEW
 LX5251'LONDON, GO S ON THE PLEASANT BEACH ROAD FOR 3.3 MI. TO A
 LX5251'T-ROAD.  TURN RIGHT AND GO 0.2 MI. TO A GATE ON THE RIGHT, TURN
 LX5251'RIGHT AND PASS THROUGH THE GATE AND FOLLOW A DIRT ROAD FOR 0.7
 LX5251'MI. TO ARMY BUILDINGS.  CONTINUE STRAIGHT AHEAD ON THE ROAD THAT
 LX5251'PARALLELS THE BEACH AND GOLF COURSE FOR 0.2 MI. TO THE STATION
 LX5251'ON THE LEFT.

 LX5251
 LX5251'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1948 (RJS)
 LX5251'THIS STATION WAS RECOVERED AS DESCRIBED BUT REFERENCE MARKS 1 AND
 LX5251'2 WERE NOT FOUND.  LOCAL INFORMATION DECLARES THAT REFERENCE MARK
 LX5251'1 IS STILL IN.  A THIRD REFERENCE MARK WAS FOUND APPROXIMATELY E
 LX5251'OF STATION AT ABOUT THE MEAN LOW-WATER LINE AND WAS STAMPED
 LX5251'GOSHEN R M NO 3 1943.

 LX5251                          STATION RECOVERY (1954)
 LX5251
 LX5251'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1954 (LFW)
 LX5251'THE STATION AND REFERENCE MARKS 1 AND 2 WERE RECOVERED.  THE
 LX5251'ORIGINAL DESCRIPTION BY G.C.M. IS ADEQUATE, EXCEPT THAT THE
 LX5251'E.S. HARKNESS ESTATE IS NOW THE HARKNESS MEMORIAL STATE PARK.  THE
 LX5251'NINE-HOLE GOLF COURSE HAS BEEN ABANDONED.
 LX5251'
 LX5251'REFERENCE MARKS 3 AND 4 ESTABLISHED BY F.N. IN 1943 COULD NOT
 LX5251'BE FOUND.  THE SEAWALL HAS BEEN BADLY DAMAGED BY STORM WAVES,
 LX5251'AND IT IS PROBABLE THAT THESE TWO MARKS ARE LOST.
 LX5251'
 LX5251'IT WILL BE NOTED THAT THE DISTANCES AND DIRECTIONS TO REFERENCE
 LX5251'MARKS 1 AND 2 DO NOT CHECK THE OBSERVATIONS BY G.C.M. IN
 LX5251'1934.  THESE MARKS ARE NOW OUTSIDE THE STORM HIGH-WATERLINE.  IT
 LX5251'IS QUITE PROBABLE THAT THE BOULDERS HAVE BEEN SHIFTED BY STORM
 LX5251'WAVES AND EROSION.  IT APPEARS, HOWEVER, THAT THE STATION MARK
 LX5251'HAS NOT MOVED APPRECIABLY SINCE IT FURNISHED A SATISFACTORY
 LX5251'THIRD-ORDER CHECK FOR THE LOCATION OF INTERSECTION STATION
 LX5251'BARTLETT REEF LIGHT.  THE STATION IS IN A MUCH LARGER
 LX5251'BOULDER THAN EITHER REFERENCE MARK 1 OR REFERENCE MARK 2.

 LX5251'LETTER OF PHILIP W. GENOVESE AND ASSOC. NEW HAVEN, CONN. DATED
 LX5251'MAY 13, 1965--
 LX5251'
 LX5251'STATION MARK IS ABOUT 2 FEET FROM EDGE OF LARGE BOULDER NOT ON
 LX5251'HIGH POINT.  BOULDER APPEARS TO HAVE ROLLED DUE TO EROSION OF
 LX5251'UNDERLYING SAND.  REFERENCE MONUMENTS APPEARED UNDISTURBED.
 LX5251'
 LX5251'R.M. 1 IS 41.41 FEET FROM STATION.  R.M. 2 IS 54.38 FEET FROM
 LX5251'STATION.  R.M. 1 TO R.M. 2 IS 44.805 FEET.

 LX5251'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1965 (WFD)
 LX5251'ONE POSITION ONLY WAS TAKEN FROM A PRECARIOUS SETUP FOR THE
 LX5251'FOLLOWING 1965 ANGLES, NEW LONDON LEDGE LIGHTHOUSE 1932 AS
 LX5251'INITIAL--
 LX5251'
 LX5251'STATION MARK, RMS 1, 2, AND 3 WERE RECOVERED, RM 4 WAS NOT
 LX5251'FOUND.  THE BOULDER CONTAINING THE STATION DISK APPEARS TO HAVE
 LX5251'BEEN DRAGGED SEAWARD MORE THAN 1/2 METER BY UNDERMINING WAVE
 LX5251'ACTION, AS NEITHER ANGLES NOR DISTANCES TO THE RMS CHECKED.  IT IS
 LX5251'POSSIBLE THAT RMS 1 AND 3 MAY HAVE BEEN SIMILARLY DISTURBED, THE
 LX5251'BULK OF THE BOULDERS IN WHICH THEY ARE SET APPARENTLY BEING
 LX5251'ABOVE GROUND.  RM 1 IS ABOUT STORM TIDE WATER LINE.  RM 3 BELOW
 LX5251'NORMAL WATER LEVEL.
 LX5251'
 LX5251'STATION MARK IS NOT IN THE HIGHEST PART OF THE BOULDER, NOR IS IT
 LX5251'CENTERED, BUT A LATIN INSCRIPTION CHISELED IN THE SOUTHERN FACE
 LX5251'OF THE BOULDER WITH DATE 1889 IS HORIZONTAL WHICH WOULD SEEM TO
 LX5251'INDICATE THE BOULDER HAD SLID SEAWARD RATHER THAN ROLLED.  ROUGHLY
 LX5251'TRIANGULAR, THE BOULDER IS ABOUT 4 FEET HIGH WITH 9-FOOT SIDES.
 LX5251'
 LX5251'THE FORMER HARKNESS ESTATE IS NOW HARKNESS MEMORIAL PARK, AND
 LX5251'STREET NAMES HAVE BEEN CHANGED.  TO REACH THE STATION FROM
 LX5251'WATERFORD, CONN., GO SOUTHWEST ON STATE ROUTE 156 A SHORT WAY TO
 LX5251'THE JUNCTION OF STATE ROUTES 156 AND 213, GO LEFT AND FOLLOW 213
 LX5251'SOUTHWARD FOR 3.3 MILES TO THE ENTRANCE TO HARKNESS MEMORIAL
 LX5251'STATE PARK ON THE RIGHT, TURN RIGHT AND PASS THE PARKING AREA AND
 LX5251'THE PICNIC AREA TO THE BEACH, GO LEFT ALONG THE SHORE LINE FOR
 LX5251'0.1 MILE TO THE STATION ON THE RIGHT.  (HARKNESS MANSION IS NOW A
 LX5251'MUSEUM, AND THE GOLF COURSE IS GONE.) THE BOULDER LAYS BETWEEN
 LX5251'A POINT OF MANY BOULDERS (VISIBLE AT LOW WATER) AND A POINT OF
 LX5251'EXPOSED BEDROCK.

 LX3785
 LX3785'DESCRIBED BY COAST AND GEODETIC SURVEY 1932 (SBG)
 LX3785'LOCATED ON THE N SIDE OF THE CHANNEL ABOUT 3/4 MILE SE OF
 LX3785'CALF-PASTURE POINT.  THE STATION IS A BEACON BUILT ON A REEF.  THE
 LX3785'BODY OF THE BEACON IS A WHITE FRUSTRUM OF A SQUARE PYRAMID
 LX3785'SURMOUNTED BY A RED STEEL LATTICE WORK WHICH SUPPORTS THE
 LX3785'LIGHT.  THE CENTER OF THE LANTERN MARKS THE STATION.

 LX3785
 LX3785'RECOVERY NOTE BY US GEOLOGICAL SURVEY 1951
 LX3785'BEACON WAS BLOWN OVER DURING A GALE IN NOVEMBER, 1950, AND AS YET
 LX3785'HAS NOT BEEN RIGHTED.  A LIGHT ON A WOODEN POLE HAS BEEN ERECTED
 LX3785'AS A GUIDE TO SHIPPING IN THE APPROXIMATE LOCATION OF THE ORIGINAL
 LX3785'BEACON, BUT CANNOT BE USED AS A TRIANGULATION STATION.

 LX3785'RECOVERED AS DESCRIBED IN FIRST TWO SENTENCES OF DESCRIPTION.
 LX3785'
 LX3785'THIRD AND FOURTH SENTENCES SHOULD READ--BEACON IS A STEEL TOWER,
 LX3785'PAINTED RED AT BOTTOM, WHITE IN MIDDLE SECTION, AND RED AT
 LX3785'TOP.  CENTER OF LIGHT MARKS THE STATION.
 LX3785'
 LX3785'NOTE--LOCAL BOATMEN TELL ME THE OLD BEACON WAS BADLY DAMAGED, A
 LX3785'FEW YEARS AGO, BY ONE OF THE HURRICANES, AND HAS BEEN REBUILT.  THE
 LX3785'COAST GUARD MAY HAVE A RECORD OF THE REBUILDING DATE, AND WHETHER
 LX3785'OR NOT THE LIGHT IS EXACTLY OVER OLD LOCATION.  I KNOW THE BEACON
 LX3785'IS O.K. FOR PILOTING (I USED IT, THIS PAST SUMMER), BUT IT COULD
 LX3785'BE SLIGHTLY OFF POSITION FOR ACCURATE TRIANGULATION WORK.
 LX3785'
 LX3785'OFFICE NOTE--LIGHT LIST INDICATES THAT THE LIGHT HAS NOT BEEN
 LX3785'REBUILT SINCE 1924.

 KU2883'RECOVERY NOTE BY NOS ATLANTIC MARINE CENTER 1990 (CSM)
 KU2883'THE STATION IS LOCATED NEAR THE NORTH SHORE OF LONG ISLAND SOUND ABOUT
 KU2883'2.1 NAUTICAL MILES SOUTH OF THE VILLAGE OF GREENWICH, CONNETICUT, ON
 KU2883'GREAT CAPTAIN ISLAND NEAR THE SOUTHEAST SIDE OF THE ISLAND.  THE
 KU2883'LIGHTHOUSE IS NO LONGER ACTIVE OR MAINTAINED BY THE U.S. COAST GUARD
 KU2883'AND THE ISLAND AND LIGHTHOUSE ARE NOW THE PROPERTY OF THE VILLAGE OF
 KU2883'GREENWICH.  THERE IS A RESIDENT CARETAKER (MR OTTO LAURESDORF) WHO
 KU2883'RESIDES IN THE DWELLING WHICH IS ATTACHED TO THE LIGHTHOUSE.  THE U.S.
 KU2883'COAST GUARD HAS REPLACED THE LIGHTHOUSE WITH A MODERN LIGHT AFFIXED TO
 KU2883'A SKELETON STEEL TOWER SOME 100 M (328.1 FT) SOUTHEAST OF THE OLD
 KU2883'LIGHTHOUSE WHICH WAS CONSTRUCTED IN 1868.  THE STATION MAY BE REACHED
 KU2883'BY BOAT BY APPROACHING FROM THE SOUND SIDE OF THE ISLAND AND LANDING
 KU2883'AT THE COASTGUARD MAINTAINED PIER IN THE VICINITY OF THE NEW
 KU2883'NAVIGATIONAL LIGHT.  LIGHTHOUSE IS A WHITE STONE TOWER ATTACHED TO THE
 KU2883'SOUTH GABLE OF A GRANITE STONE DWELLING ON THE SOUTHEAST PART OF THE
 KU2883'ISLAND AND THE POINT OBSERVED WAS THE SPIKE AT THE TOP CENTER OF THE
 KU2883'OLD LIGHT HOUSING.  THE SPIKE IS NOW BENT AND MAY PRESENT DIFFICULTY
 KU2883'WHEN OBSERVING AT CLOSE RANGE BUT IS OF NO CONSEQUENCE OVER MEDIUM TO
 KU2883'LONG LINES.  AT THE TIME OF RECOVERY THE CARETAKER WAS WILLING TO
 KU2883'ALLOW ACCESS TO THE LIGHT HOUSING AND WAS QUITE HELPFUL.  RECOVERED BY

 LX6140'DESCRIBED BY COAST AND GEODETIC SURVEY 1934
 LX6140'THERE IS NO PREVIOUS DESCRIPTION.  THE CHURCH IS ON THE WEST SIDE OF
 LX6140'ROUTE 9, 1/4 MILE ABOVE THE HADDAM JAIL.  IT IS A WHITE WOODEN
 LX6140'BUILDING WITH FOUR LONG GREEN-SHUTTERED WINDOWS IN THE NORTH AND SOUTH
 LX6140'SIDES.  AT THE TOP OF THE ENTRANCE STEPS ARE TWO DORIC COLUMNS
 LX6140'SUPPORTING THE PEDIMENT.  THE TOWER RISES JUST INSIDE THE EAST WALL OF
 LX6140'THE CHURCH.  DIRECTLY ABOVE THE ROOF IS A PLAIN SQUARE SECTION ABOUT
 LX6140'SIX FEET HIGH.  THEN THE SQUARE BELFRY WITH RECTANGULAR GREEN LOUVRES
 LX6140'IN EACH SIDE.  ABOVE THIS IS AN ENCLOSED SECTION SMALLER BUT EQUAL IN
 LX6140'HEIGHT TO THE BELFRY SECTION.
 LX6140'
 LX6140'A FEATURE OF THE BELFRY AND THE SECTION ABOVE IS THE COLUMNS OUTSIDE
 LX6140'THE WALLS.
 LX6140'
 LX6140'THE TOWER ROOF IS HEMISPHERICAL AND PAINTED YELLOW.  ABOVE IS AN
 LX6140'ORNATE WEATHER VANE.
 LX6140'
 LX6140'CENTER IS THE AXIS OF THE VANE.
 LX6140'
 LX6140'OF LITTLE USE AS A LANDMARK BECAUSE IT IS SCREENED BY TREES.  TOWER IS
 LX6140'ABOUT 60 FEET HIGH.

 LX3645
 LX3645'DESCRIBED BY COAST AND GEODETIC SURVEY 1933 (GCM)
 LX3645'THIS STATION IS ON THE WATER TANK AND WINDMILL AT HAYLAND
 LX3645'FARM.  THE TANK IS OF WOOD WITH SHINGLE ROOF AND FLAT BOTTOM ON
 LX3645'A STEEL SUPPORTING FRAMEWORK.  A SMALL BUILDING HOUSING THE
 LX3645'PUMP IS INSIDE THE FOUR LEGS AT THE GROUND.
 LX3645'
 LX3645'THE STRUCTURE CONTINUES ABOVE THE TANK AND SUPPORTS THE
 LX3645'WINDMILL.  THERE IS A WOODEN PLATFORM, WITHOUT A RAIL, JUST
 LX3645'BELOW THE ROTOR.
 LX3645'
 LX3645'CENTER IS THE APEX OF THE STEEL SUPPORTING
 LX3645'STRUCTURE.  TRIANGULATION STATION HAY IS 26.27 METERS DISTANT.

 LX3645'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1962 (CHO)
 LX3645'RECOVERED AS DESCRIBED, EXCEPT THAT THE TANK AND WINDMILL IS
 LX3645'SUFFERING FROM OLD AGE, AND LACK OF MAINTENANCE REPAIRS--
 LX3645'
 LX3645'PUMP IS NO LONGER IN USE.
 LX3645'
 LX3645'SHINGLE ROOF OF TANK IS GONE.  WINDMILL, AS SUCH, DOES NOT
 LX3645'FUNCTION, AND SHINGLE ROOF OF TANK IS GONE.  WOODEN PLATFORM
 LX3645'WITHOUT A RAIL IS ALSO GONE.
 LX3645'
 LX3645'HOWEVER, OLD VERTICAL SUPPORT OF FORMER ROTOR BLADES AND VANE
 LX3645'EXTENDS VERTICALLY ABOVE CENTER OF APEX OF OLD SUPPORTING
 LX3645'STRUCTURE, AND CAN BE SIGHTED UPON, AS IF IT WERE THE ORIGINAL
 LX3645'STATION.
 LX3645'
 LX3645'MR. TREATS DAUGHTER SAID THEY HAD TRIED TO GET BIDS TO
 LX3645'DISMANTLE THE OLD WINDMILL, BUT THE COST IS PROHIBITIVE, AND NO
 LX3645'ONE REALLY WANTS TO DO THE WORK.  AS LONG AS IT REMAINS STANDING
 LX3645'IT IS A HELPFUL LANDMARK TO FIND STATION HAY.

 LX7641
 LX7641'DESCRIBED BY NATIONAL GEODETIC SURVEY 1983 (CLN)
 LX7641'THIS STATION WAS ESTABLISHED DUE TO STATION HOFMAN 1935 BEING IN THE
 LX7641'WAY FOR A NEW HOUSE.  HOFMAN 1935 WAS DESTROYED AFTER THIS STATION
 LX7641'WAS ESTABLISHED.  THE AZIMUTH MARK FOR STATION HOFMAN 1935 IS
 LX7641'OBSTRUCTED BY TREES AT THE PRESENT TIME.
 LX7641'
 LX7641'THE STATION IS LOCATED ABOUT 8 KM (5 MI) NORTH OF MIDDLETOWN, 5.6 KM
 LX7641'(3.5 MI) EAST OF BERLIN, 4.0 KM (2.5 MI) NORTHWEST OF
 LX7641'CROMWELL AND AT THE
 LX7641'SOUTH PROPERTY LINE FOR AN UNDERGROUND RESERVOIR OWNED BY THE TOWN OF
 LX7641'CROMWELL.  IT IS ABOUT 35 YARDS NORTH OF THE PROPOSED NORTHWEST CORNER
 LX7641'OF A HOUSE.

 LX6146
 LX6146'DESCRIBED BY COAST AND GEODETIC SURVEY 1934 (GCM)
 LX6146'THIS STATION IS ON THE PROPERTY OF S.R. LATSHAW.  IT IS ON A
 LX6146'HILL SW OF ROUTE 9 ABOUT 1 MILE ABOVE THE MIDDLESEX COUNTY
 LX6146'JAIL.  IT IS BEST REACHED FROM THE SOUTHWARD FROM THE OLD MAIN
 LX6146'HIGHWAY LAYOUT.  THIS ROAD PASSES THE PRESENT LATSHAW RESIDENCE
 LX6146'AND THEN A PRIVATE ROAD LEADS TO THE TOP OF THE HILL.
 LX6146'
 LX6146'STATION MARK IS A STANDARD BRONZE DISK WEDGED IN A DRILL HOLE
 LX6146'IN OUTCROPPING BEDROCK AS DESCRIBED IN NOTE 2.  REFERENCE MARK
 LX6146'NO.1 AND REFERENCE MARK NO.2 ARE STANDARD BRONZE DISK SET
 LX6146'IN OUTCROPPING BEDROCK AS DESCRIBED IN NOTES 12A.
 LX6146'
 LX6146'THE HILLTOP HAS BEEN GRADED AS SITE FOR A FUTURE RESIDENCE.  THE
 LX6146'FLAT AREA IS ABOUT 150 BY 50 METERS, ELLIPTICAL IN SHAPE, WITH
 LX6146'A DRIVE AROUND THE EDGE.  AXIS LIES ABOUT N AND S.
 LX6146'
 LX6146'THE STATION IS ABOUT MIDWAY OF THE E SIDE OF THE HILLTOP
 LX6146'AND 6 METERS E OF THE CENTER LINE OF THE DRIVE.  HERE THE
 LX6146'LEDGE OUTCROPS AT THE BROW OF THE HILL, ON A LEVEL WITH THE
 LX6146'TOP.  THE LEDGE IS ABOUT 10 METERS LONG AND EXTENDS ABOUT 6
 LX6146'METERS DOWN THE EASTERLY SLOPE.  THE STATION IS ON THE
 LX6146'HIGHEST PART OF THE LEDGE.
 LX6146'
 LX6146'REFERENCE MARK NO.1 IS IN A FLAT LEDGE CONFORMING TO THE
 LX6146'EASTERLY SLOPE OF THE HILLSIDE AND ABOUT 10 METERS E OF THE
 LX6146'BROW OF THE HILL.  THE LEDGE IS ABOUT 17 METERS IN A
 LX6146'NORTHEASTERLY AND SOUTHWESTERLY DIRECTION.  REFERENCE MARK
 LX6146'IS 1.5 METERS INSIDE SOUTHWESTERLY END.  IT BEARS N 30 DEG E
 LX6146'(MAGNETIC).
 LX6146'
 LX6146'REFERENCE MARK NO.2 IS IN A SIMILAR LEDGE SOMEWHAT LOWER THAN
 LX6146'THE STATION.  THIS LEDGE DROPS 8 FEET STRAIGHT DOWN ON THE
 LX6146'EASTERLY SIDE.  IT IS ABOUT 35 METERS NORTHERLY OF A S
 LX6146'BOUNDARY FENCE.  REFERENCE MARK BEARS S 50 DEG E (MAGNETIC).

 LX5812'DESCRIBED BY COAST AND GEODETIC SURVEY 1934 (GCM)
 LX5812'THIS TOWER IS PART OF THE WATER SUPPLY SYSTEM ON THE R.D. ELY
 LX5812'ESTATE ON LORDS HILL.  IT IS NOT ON THE HIGHEST PART OF THE HILL
 LX5812'BUT IS ABOUT 170 METERS SOUTHWESTERLY.  THE TOP OF THE HILL IS
 LX5812'OCCUPIED BY A SMALL HEXAGONAL SUMMER HOUSE.
 LX5812'
 LX5812'THE WATER TANK IS ENCLOSED IN A SQUARE STONE MASONRY STRUCTURE,
 LX5812'ABOUT 12 FEET ON A SIDE AND APPROXIMATELY 30 FEET HIGH.  THE WALLS
 LX5812'HAVE BEEN CARRIED UP AT THE CORNERS TO FORM FOUR SMALL PROJECTIONS
 LX5812'ABOUT TWO FEET HIGH.  TWO OPENINGS HAVE BEEN LEFT IN EACH SIDE
 LX5812'ABOUT 15 FEET ABOVE THE GROUND.
 LX5812'
 LX5812'CENTER IS THE CENTER LINE OF THE TOWER.
 LX5812'
 LX5812'THE TOWER IS OF LIMITED USE AS A LANDMARK BECAUSE IT BLENDS
 LX5812'NATURALLY WITH THE SURROUNDING TREES.

 LX4853
 LX4853'RECOVERY NOTE BY CONNECTICUT GEODETIC SURVEY 1986 (WB)
 LX4853'STATION MARK, AZIMUTH MARK AND REFERENCE MARK 1 WERE RECOVERED AND
 LX4853'FOUND IN GOOD CONDITION.  REFERENCE MARK 2 WAS NOT FOUND AND PRESUMED
 LX4853'DESTROYED BECAUSE OF EXCAVATION IN THE AREA.  THE DISTANCE TO THE AZ
 LX4853'MK DIFFERED BY 0.010 METERS.  THE DISTANCE TO RM 1 DIFFERED BY 0.04
 LX4853'FEET AND THE DIRECTION FROM THE AZ MK TO RM 1 DIFFERED BY 17.95
 LX4853'SECONDS. RM 3 WAS ADDED AT HIS TIME BECAUSE IT IS ANTICIPATED THAT THE
 LX4853'AZ MK WILL BE DESTROYED DUE TO HOME CONSTRUCTION.  IT IS ALSO A
 LX4853'POSSIBILITY THAT THE STATION MARK COULD BE DESTROYED AT SOME TIME IN
 LX4853'THE FUTURE BECAUSE OF NEW HOUSING.  HOWEVER AT THIS TIME THE PRESENT
 LX4853'OWNER HAS NO IMMEDIATE PLANS TO BUILD.  CTGS CONTACTED THE LANDOWNER
 LX4853'BY LETTER AND HE WAS MADE AWARE OF THE STATION MARK AND RM 1.  AN

 LX3702'DESCRIBED BY COAST AND GEODETIC SURVEY 1908 (HPR)
 LX3702'STATION LOCATED ON THE LAND OF THE CLARKES, USUALLY CALLED CLARKES
 LX3702'HILL.  THE CLEARED HILL IMMEDIATELY NE IS CALLED EELS HILL.  SIGNAL
 LX3702'IS IN OPEN FIELD, ON THE ROAD FROM MILFORD TO WESTHAVEN, NEAR
 LX3702'FIRST TURN TO LEFT AFTER PASSING THE ROAD LEADING TO POND
 LX3702'POINT.  THERE IS A DWELLING HOUSE CLOSE TO SIGNAL.  THE FIELD IS
 LX3702'THE SECOND ONE FROM THE ROAD AND CONTAINS SEVERAL TREES.
 LX3702'MEASURES WERE MADE TO TWO TREES ALONG THE E FENCE OF THE FIELD.
 LX3702'TO THE N WALNUT TREE IS 201 FEET, 8 INCHES.  TO THE S WALNUT
 LX3702'TREE IS 67 FEET.  THE TREES ARE 249 FEET APART.  MARKING NOT
 LX3702'DESCRIBED IN ORIGINAL DESCRIPTION.  IN 1871 THE STATION WAS
 LX3702'RECOVERED ACCORDING TO E. GOODFELLOW, BUT THE DISTANCES
 LX3702'HE GIVES ARE NOT IN ACCORD WITH THOSE ABOVE.  HE GIVES THE
 LX3702'DISTANCES USED IN THE RECOVERY AND IDENTIFICATION AS--TO N
 LX3702'WALNUT TREE 201.8 FEET.  S WALNUT TREE 142 FEET.  APPLE TREE
 LX3702'74.6 FEET.  THESE DISTANCES BROUGHT THE POINT TO WITHIN 3
 LX3702'FEET OF THE POINT INDICATED ON THE GROUND BY ASA CLARKE, OWNER
 LX3702'OF THE GROUND AND RESIDENT OF THE PREMISES AT TIME STATION
 LX3702'WAS ESTABLISHED.  THE UNDERGROUND MARK IS A SECTION OF TERRA
 LX3702'COTTA DRAIN PIPE 9-1/2 INCHES UPPER DIAMETER, 7-3/4
 LX3702'INCHES AT BOTTOM AND 8-1/2 INCHES LONG, BURIED 2-3/4 FEET
 LX3702'BELOW SURFACE OF GROUND.  IN CENTER OF CYLINDER WAS PLACED A
 LX3702'CHESTNUT STAKE WITH COPPER NAIL IN TOP TO MARK CENTER.
 LX3702'TOP OF STAKE IS 19 INCHES BELOW SURFACE OF
 LX3702'GROUND.  STATION WAS MARKED ON SURFACE BY CHESTNUT STAKE WITH
 LX3702'COPPER NAIL IN CENTER.  THE S WALNUT TREE BEARS E OF S (TRUE)
 LX3702'71 DEG 33 MIN.  APPLE TREE BEARS E OF N (TRUE) 58 DEG 26
 LX3702'MIN.  N WALNUT TREE BEARS W OF N (TRUE) 40 DEG 10 MIN.
 LX3702'
 LX3702'IN 1881 G. BRADFORD FOUND THE SIGNAL STANDING AND DIGGING UNDER
 LX3702'CENTER POLE FOUND NO MARKS EXCEPT A BIT OF POINTED WOOD, ROTTEN
 LX3702'WHICH MAY HAVE BEEN THE CHESTNUT STAKE DESCRIBED BY GOODFELLOW.
 LX3702'
 LX3702'IN 1884 W.C. HODGKINS FOUND THE REMAINS OF THE OLD TRIPOD LYING
 LX3702'NEAR THE STATION, WHICH WAS MARKED BY A TACK IN AN ASH STAKE
 LX3702'BURIED IN THE GROUND AND SURROUNDED BY STONES.  THE UNDERGROUND
 LX3702'MARK WAS NOT SEARCHED FOR.  ADDITIONAL REFERENCES WERE ESTABLISHED
 LX3702'AS FOLLOWS--HOLES WERE DRILLED IN TWO BOULDERS BURIED IN THE
 LX3702'GROUND.  THE HOLES WERE 86 FEET, 9 INCHES APART.  THE ANGLES AT
 LX3702'THE STATION FROM S.W. LEDGE L.H. TO HOLES AND THEIR DISTANCES
 LX3702'WERE--59 DEG 33 MIN, 59 FEET, 9 INCHES.  135 DEG 11 MIN, 92
 LX3702'FEET 1 INCH.
 LX3702'
 LX3702'IN 1904 J.B. BAYLOR FOUND THE TERRA COTTA DRAIN PIPE PLACED
 LX3702'HERE IN 1833 OR 1871.  IT WAS IN GOOD CONDITION.  THE REFERENCE
 LX3702'TREES HAD DISAPPEARED.  THE REFERENCE ROCKS WERE FOUND.  THEIR
 LX3702'ANGLES FROM S.W.LEDGE L.H. AND DISTANCES FROM STATION WERE--
 LX3702'224 DEG 15 MIN, 92.85 FEET.  289 DEG 42 MIN, 59.30 FEET.  THE
 LX3702'DISTANCES CHECK RATHER POORLY, AND ASSUMING THAT THE ANGLES WERE
 LX3702'MEASURED IN REVERSE DIRECTIONS, THAT IS THAT THE 1904 ANGLES
 LX3702'ARE EXPLEMENTS OF THE 1884 ANGLES, THE DISAGREEMENT IS MARKED
 LX3702'FOR THE NEARER ROCK.
 LX3702'
 LX3702'IN 1904 A NEW SURFACE MARK WAS PLACED, CONSISTING OF A BLOCK
 LX3702'OF DRESSED GRANITE 18 INCHES SQUARE AND 8 INCHES THICK, WITH
 LX3702'DRILL HOLE AND TRIANGLE ON TOP.  TOP OF ROCK IS 3 INCHES BELOW
 LX3702'SURFACE OF GROUND.  THE CLARKE FAMILY STILL OWNED THE PROPERTY.
 LX3702'
 LX3702'IN 1908 H.P.RITTER VISITED THE STATION AND RECOVERED THE
 LX3702'GRANITE BLOCK SURFACE MARK, LIKEWISE THE TWO REFERENCE ROCKS WITH
 LX3702'DRILL HOLES IN TOP.  HE DID NOT SEARCH FOR THE SUB-SURFACE
 LX3702'MARK.  THE LETTERS U.S. WERE CUT IN THE TOP OF THE GRANITE
 LX3702'BLOCK, ONE ON EITHER SIDE OF THE APEX OF THE TRIANGLE.

 LX3702'THE EXCEPTION THAT ONE REFERENCE MARK COULD NOT BE FOUND.  A
 LX3702'FEW DAYS PRIOR TO OUR RECOVERY (LT. (J.G.) G.R. SHELTON) THE FIRST
 LX3702'ORDER RECONNAISSANCE PARTY UNDER LIEUT. F.L. GALLEN LIKEWISE
 LX3702'SEARCHED FOR AND RECOVERED THIS MARK.  AFTER CONFERRING WITH HIM
 LX3702'IT WAS MUTUALLY DECIDED THAT THE RECOVERY WAS SATISFACTORY,
 LX3702'AND HIS INTENTION IS TO ASSUME IT TO BE CORRECT FOR USE IN
 LX3702'FIRST ORDER WORK IN 1932.  OUR USE OF IT IN 1931 WAS FOR THIRD
 LX3702'ORDER WORK ONLY IN LOCATING BREAKWATER LIGHTS IN THE
 LX3702'HARBOR.  LIEUT. GALLEN INTENDS TO RE-MARK THE STATION
 LX3702'WHEN IT IS OCCUPIED IN 1932.

 LX0761'DESCRIBED BY COAST SURVEY (CGS) 1863 (EB)
 LX0761'DESCRIPTION OF SIGNAL ERECTED SEPT. 11, 1863 ON LAND BELONGING TO
 LX0761'ALBERT ANSON, WASHINGTON TOWNSHIP.
 LX0761'
 LX0761'SIGNAL ERECTED ON HIGHEST PART OF MT. TOM.  STATION MARKED BY HOLE
 LX0761'DRILLED IN LEDGE.  THE STATION IS AT THE EXTREME SW END OF THE SUMMIT
 LX0761'WHICH FALLS GRADUALLY FOR 20 OR 30 RODS TOWARDS THE NE.  THE SIGNAL
 LX0761'HAS A BARREL NEAR THE TOP.  AN OBSERVATION WAS MADE WITH THE BAROMETER
 LX0761'EACH DAY.
 LX0761'
 LX0761'DIMENSIONS OF SIGNAL--CROTCH TO GROUND, 9 FEET 10 INCHES.  CROTCH TO
 LX0761'TOP OF BARREL, 14 FEET 8-1/2 INCHES.  TOP OF BARREL TO TOP OF POLE, 1
 LX0761'FOOT 11 INCHES.  TOTAL HEIGHT, 26 FEET 5-1/2 INCHES.
 LX0761'
 LX0761'ABOVE THE BARREL A PIECE OF WHITE CANVAS WAS FASTENED AS A FLAG.  MR.
 LX0761'CHESTER C. GOSLEE AND HIS SONS ASSISTED IN THE ERECTION OF THE SIGNAL.
 LX0761'A HELIOTROPE WAS LEFT IN CARE OF C.C. GOSLEE AT HIS HOUSE.  MR. GOSLEE
 LX0761'LIVES ABOUT 1-1/2 MILES FROM THE MOUNTAIN.  HIS P.O. ADDRESS IS BANLAM
 LX0761'FALLS, LITCHFIELD COUNTY, CONN.  THOUGH SOMEWHAT DISTANT, MR. GOSLEES
 LX0761'WILL PROBABLY BE FOUND THE MORE CONVENIENT AND AGREEABLE PLACE FOR A
 LX0761'HELIOTROPER TO OBTAIN BOARD.  IN APPROACHING MT. TOM STATION FROM
 LX0761'LITCHFIELD THE SHORTER WAY IS TO LEAVE TOWN BY WEST ST. AND TAKE THE
 LX0761'ROAD TO NEW PRESTON, ABOUT 5 MILES FROM LITCHFIELD AND A LITTLE BEYOND
 LX0761'A FORK TO THE RIGHT WHICH LEADS TO MT. PROSPECT COPPER MINES.  THERE
 LX0761'IS A FORK TO THE LEFT WHICH IS CALLED THE NEW ROAD TO NEW MILFORD VIA
 LX0761'PRESTON OR MARBLEDALE.  ONE MILE FROM THE TURN A CROSS ROAD N AND E IS
 LX0761'MET AND C.C. GOSLEE LIVES TO THE NORTHWARD OF THE CORNERS ABOUT ONE
 LX0761'QUARTER OF A MILE.  THE NEW ROAD LEAVES THE POND (MT. TOM POND) TO THE
 LX0761'SOUTHWARD A SHORT DISTANCE BEYOND THE CORNERS.  THE FIRST LEFT-HAND
 LX0761'(S) TURN FROM THE CORNERS, WHICH IS BEYOND OR W OF THE POND, GIVES THE
 LX0761'BEST ASCENT TO THE MOUNTAIN, BEARING ALWAYS TO THE LEFT.  YOU APPROACH
 LX0761'WITH A CARRIAGE WITHIN A SHORT HALF MILE OF THE SUMMIT.  AN OLD HORSE
 LX0761'TRACK LEADS WITHIN A FEW RODS OF THE STATION TO WHICH A SMALL PATH WAS
 LX0761'CLEARED.  BY CLEARING, THE HORIZON WAS MADE VISIBLE FROM THE NE AROUND
 LX0761'BY S TO NW.
 LX0761'
 LX0761'NOTE-IN SEPTEMBER, 1865 THE BARREL WAS FOUND TO BE ECCENTRIC 10 INCHES
 LX0761'S OF THE STATION.  THE TRIPOD HEAD WAS CORRECT.  THE DEFLECTION OF THE
 LX0761'POLE TO THE SOUTHWARD BEGAN VERY NEAR THE TRIPOD HEAD.  IT MUST HAVE
 LX0761'BEEN OCCASIONED SOON AFTER THE SIGNAL WAS ERECTED, BY THE FALL WINDS,
 LX0761'WHEN THE POLE WAS GREEN.
 LX0761'
 LX0761'FROM A LETTER, DATED OCT. 6, 1915, FROM PROF. J.K. FINCH, DEPT. OF
 LX0761'CIVIL ENGINEERING, COLUMBIA UNIVERSITY, NEW YORK--

 AC7673.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 AC7673.been affixed to the stable North American tectonic plate. See 
 AC7673.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 AC7673
 AC7673.The horizontal coordinates are valid at the epoch date displayed above
 AC7673.which is a decimal equivalence of Year/Month/Day.
 AC7673
 AC7673.The orthometric height was determined by GPS observations and a
 AC7673.high-resolution geoid model.
 AC7673
 AC7673.GPS derived orthometric heights for airport stations designated as
 AC7673.PACS or SACS are published to 2 decimal places.  This maintains
 AC7673.centimeter relative accuracy between the PACS and SACS.  It does
 AC7673.not indicate centimeter accuracy relative to other marks which are
 AC7673.part of the published vertical control network.

 LX5438'DESCRIBED BY COAST AND GEODETIC SURVEY 1934 (GCM)
 LX5438'THE STATION IS ON THE EXTREME END OF POND POINT, WHICH IS ON THE
 LX5438'W SIDE OF NIANTIC BAY.  IT IS A STANDARD DISC SET IN A LEDGE
 LX5438'THAT IS CUT OFF FROM THE MAINLAND AT HIGH WATER.  THE TOP OF THE
 LX5438'LEDGE IS ABOUT TWO FEET ABOVE HIGH WATER.
 LX5438'
 LX5438'REFERENCE MARK NO.1 IS A STANDARD DISC SET IN THE SAME LEDGE,
 LX5438'SW OF THE STATION.  IT TOO IS COVERED AT HIGH WATER.  REFERENCE
 LX5438'MARK NO.2 IS A STANDARD DISC SET IN A SMALL BOULDER W OF THE
 LX5438'STATION AND ABOUT MIDWAY OF THE SAND SPIT W OF THE STATION.

 DH5837.NGS completed the third reprocessing of daily RINEX data from 1996 to 2022
 DH5837.for all stations in the NOAA CORS Network (NCN).  The reprocessed solution,
 DH5837.known as the Multi-Year CORS Solution 3 (MYCS3), is aligned with the
 DH5837.ITFR2020 global frame, epoch 2020.00.  The resulting MYCS3 coordinates
 DH5837.were then transformed to NAD83(2011/MA11/PA11), maintaining the currently
 DH5837.published epoch of 2010.00.

 LX7033                          STATION DESCRIPTION
 LX7033
 LX7033'DESCRIBED BY COAST AND GEODETIC SURVEY 1891 (WCH)
 LX7033'IN THE TOWNSHIP OF WETHERSFIELD, AND ON THE WEST SIDE OF THE RIDGE
 LX7033'ROAD, ALSO KNOWN AS WELLS STREET.  THE POINT IS WITHIN THE LIMITS OF
 LX7033'THE HIGHWAY (THOUGH WELL TO THE SIDE) BY PERMISSION OF THE TOWN
 LX7033'SELECTMEN.  THE ADJOINING LAND ON BOTH SIDES OF THE ROAD BELONGS TO
 LX7033'MR. H.S. WELLS.
 LX7033'
 LX7033'THE STATION IS AT THE HIGHEST PART OF THE ROAD, WHERE IT PASSES OVER A
 LX7033'LONG RIDGE.  A RATHER FLAT PIECE OF PASTURE LAND COVERED WITH CEDAR
 LX7033'TREES LIES JUST WEST OF THE STATION.  JUST IN FRONT (E) OF THE STATION
 LX7033'IS A LARGE LEDGE OF ROCK AND THE STATION SITE WAS SELECTED PARTLY WITH
 LX7033'THE VIEW OF HAVING THE UNDERGROUND MARK CUT INTO THIS LEDGE, AS IT
 LX7033'APPEARED TO DIP WESTWARD.  IT PROVED HOWEVER TO DIP SO SUDDENLY AS TO
 LX7033'BE TOO LOW FOR THIS PURPOSE.  THE STATION WAS MARKED UNDERGROUND BY A
 LX7033'TUBE OF GALVANIZED IRON 3 INCHES IN DIAMETER AND 4 INCHES HIGH SET
 LX7033'VERTICALLY IN THE GROUND, ITS LOWER RIM 2.7 FEET BELOW SURFACE OF
 LX7033'GROUND.  AXIS OF THIS TUBE MARKS CENTER.  ABOVE THIS TUBE SOME EARTH
 LX7033'WAS PLACED, AND THEN A PIECE OF PINE BOARD.  UPON THIS BOARD RESTS A
 LX7033'BLOCK OF DARK GRAY GRANITE, 2.5 FEET LONG, PROJECTING ABOUT 3 INCHES
 LX7033'ABOVE THE GENERAL SURFACE OF THE GROUND.  IT WAS SURROUNDED BY A MOUND
 LX7033'OF EARTH.  THE TOP OF THE STONE WAS DRESSED TO A SQUARE AND MARKED
 LX7033'WITH CROSS LINES, THE LETTERS U.S.C.S. BEING OUT IN THE FOUR
 LX7033'QUADRANTS.  THE TOPS OF THE LETTERS ARE TOWARD THE W.  A CROWS FOOT OR
 LX7033'BROAD ARROW WAS CUT IN THE LEDGE JUST EAST OF THE STATION, ITS POINT
 LX7033'BEING 20.15 FEET FROM THE CENTER.  FROM THE STATION THE FOLLOWING
 LX7033'DISTANCES WERE MEASURED--TO SMALL SYCAMORE TO NORTHWARD, 26.3 FEET. TO
 LX7033'SMALL SYCAMORE TO SOUTHWARD, 21.5 FEET. TO CEDAR TREE (NAIL IN
 LX7033'TRIANGLE), 65.7 FEET. TO FENCE W, 4.75 FEET. TO FENCE CORNER, N, 76.6
 LX7033'FEET. TO FENCE CORNER S, 242.0 FEET.
 LX7033'
 LX7033'IN 1930 PHILIP O. ROBERTS, TOWN ENGINEER, REPORTED THAT THE GRANITE
 LX7033'STONE MARK WAS FOUND AS DESCRIBED, BUT THAT A GREAT DEAL OF REAL
 LX7033'ESTATE AND HIGHWAY DEVELOPMENT HAD TAKEN PLACE AND ALL OTHER TIES AND
 LX7033'IDENTIFICATION MARKS HAD BEEN TAKEN AWAY AND THAT THE EARTH HAD BEEN
 LX7033'REMOVED FROM AROUND THE STONE FOR ABOUT HALF ITS LENGTH.  A CONCRETE
 LX7033'SIDEWALK WAS TO BE BUILT AT THIS SECTION AND THE STONE COMING WITHIN
 LX7033'THE SIDEWALK AREA WILL HAVE TO BE LOWERED 15 INCHES TO BRING ITS TOP
 LX7033'LEVEL WITH THE WALK GRADE.  HE PROMISED TO SEE THAT THIS WAS PROPERLY
 LX7033'DONE.

 LX3919                          STATION DESCRIPTION
 LX3919
 LX3919'DESCRIBED BY COAST AND GEODETIC SURVEY 1882 (GB)
 LX3919'STATION IS ABOUT CENTER OF A HAY LOT CROWNING THE HILL, AND
 LX3919'NEARBY WHERE THE DESCENT TO EASTWARD COMMENCES.  THE ONLY OBJECTS
 LX3919'ON THIS LOT TO WHICH MEASURES COULD BE MADE WERE TWO POPLARS TO S
 LX3919'AND E.  THE SOUTHERLY TREE IS 71 FEET, 8 INCHES FROM STATION.  THE
 LX3919'EASTERLY TREE 63 FEET 5 INCHES.  A STONE FENCE LIMITS THE LOT
 LX3919'ON THE W.  TO THE N AND S ARE RAIL FENCES.
 LX3919'
 LX3919'IN 1882 G. BRADFORD MADE AN UNSUCCESSFUL SEARCH FOR THIS
 LX3919'STATION.  REFERRING TO FARLEYS 1868 DESCRIPTION, THE APPLE TREE HAD
 LX3919'DISAPPEARED, BUT ITS ROTTEN STUMP WAS FOUND.  NO MARKS ON STONE
 LX3919'WALLS COULD BE FOUND.  THE WALLS WERE BUILT OF SMALL STONES EASILY
 LX3919'DISPLACED.  DISTANCES WERE MEASURED FROM APPLE TREE AND FROM
 LX3919'WESTERN WALL AT POINT WHERE IT WAS BELIEVED CROSS HAD BEEN, BUT
 LX3919'NOTHING WAS FOUND IN DIGGING OVER AN AREA 8 OR 9 FEET
 LX3919'ACROSS.  BRADFORD THEN ESTABLISHED ROUND HILL 2 ABOUT 24 FEET
 LX3919'TO WESTWARD OF THE SUPPOSED POSITION OF ROUND HILL AND BY
 LX3919'COMPARISON OF THE GEOGRAPHIC POSITIONS OF THE TWO STATIONS AND
 LX3919'AFTER CONSIDERABLE DIGGING FOUND A HOLLOW CYLINDER WITH
 LX3919'SLIGHT FLANGE AT TOP.  IT WAS 8-1/2 INCHES IN DIAMETER, ITS
 LX3919'TOP 19 INCHES BELOW THE SURFACE OF THE GROUND.  FROM THIS
 LX3919'CYLINDER TO REMAINS OF APPLE TREE (DESCRIPTION OF 1868) WAS 165
 LX3919'FEET.  TO SOUTHERN STONE WALL BETWEEN REMAINS OF APPLE TREE AND
 LX3919'RAIL FENCE, 160 FEET, 8 INCHES.  TO WESTERN FENCE AT
 LX3919'POINT NEAREST CYLINDER, 196 FEET, 7 INCHES.  THE CYLINDER WAS
 LX3919'APPARENTLY EMBEDDED IN CEMENT AND FIRMLY FIXED.  OYSTER
 LX3919'SHELLS WERE REPLACED OVER THE CYLINDER AND THE HOLE FILLED UP.
 LX3919'THIS CYLINDER IS SAID TO BE THE STATION UNEARTHED BY FARLEY
 LX3919'IN 1868, AND WAS PROBABLY PLACED BY BLUNT IN 1866.  FROM
 LX3919'STATION ROUND HILL TO MARKED ROCK IN S STONE WALL OF FIELD
 LX3919'AT JUNCTION WITH RAIL FENCE IS 158.75 FEET.  TO MARKED ROCK
 LX3919'IN WESTERN FENCE, 196.9 FEET.  MARKED ROCK IN S WALL IS ABOUT 2
 LX3919'FEET LONG BY 1 FOOT IN DIAMETER AND HAS ITS END TOWARD
 LX3919'STATION MARKED WITH A CROSS DEEPLY CUT.  ANGLE AT ROUND HILL
 LX3919'(CYLINDER) FROM BALD HILL 2 TO ROUND HILL 2 IS 189 DEG 20
 LX3919'MIN.  DISTANCE ROUND HILL TO ROUND HILL 2 IS 37.11 FEET.
 LX3919'
 LX3919'SEE DESCRIPTION OF ROUND HILL 2.
 LX3919'
 LX3919'IN 1908 THE STATION WAS FURTHER DESCRIBED AS BEING IN CULTIVATED
 LX3919'LAND ON THE SUMMIT OF A PROMINENT HILL OF SAME NAME LYING IN THE
 LX3919'NORTHERN PART OF GREENWICH AND 1/4 MILE W OF THE VILLAGE OF ROUND
 LX3919'HILL.  IN 1908 A BOULDER WAS SET WITH ITS BASE RESTING ON THE
 LX3919'CYLINDER (SUBSURFACE MARK) AND ITS TOP ABOUT 1 INCH BELOW
 LX3919'SURFACE OF GROUND.  A 7/8-INCH DRILL HOLE WAS SUNK 2 INCHES INTO
 LX3919'TOP OF BOULDER, OVER CENTER OF CYLINDER.

 LX3919                          STATION RECOVERY (1936)
 LX3919
 LX3919'RECOVERY NOTE BY CONNECTICUT GEODETIC SURVEY 1936
 LX3919'IN MAY 1935 THIS STATION WAS VISITED AND A CONCRETE MONUMENT
 LX3919'WITH A DISK LABELED CORPS OF ENGINEERS, U.S. ARMY, MAP CONTROL
 LX3919'STATION WAS FOUND ON TOP OF THE HILL WITH A STEEL TOWER OVER
 LX3919'IT.  THE TOWER HAD BEEN ERECTED AND USED BY A WESTCHESTER COUNTY,
 LX3919'NEW YORK SURVEYING PROJECT.  AS ALL THE REFERENCE MARKS FOR THE
 LX3919'STATION HAD DISAPPEARED IT COULD NOT BE READILY CHECKED AS
 LX3919'STATION ROUND HILL OF THE U.S. COAST AND GEODETIC SURVEY.
 LX3919'AFTER SOME CORRESPONDENCE WITH THE ARMY AUTHORITIES AT
 LX3919'PROVIDENCE AND NEW YORK WE RECEIVED THE GEOGRAPHIC
 LX3919'POSITIONS OF THEIR STATION ON ROUND HILL AND ALSO OF THE PORT
 LX3919'CHESTER HIGH SCHOOL, IN WHICH IS U.S.C. AND G.S. STATION
 LX3919'CHESTER.  BY COMPUTING BOTH LINES AND COMPARING THE RESULTS WE
 LX3919'WERE ABLE TO COMPUTE THE APPROXIMATE LOCATION OF U.S.C. AND
 LX3919'G.S. STATION ROUND HILL.  UPON DIGGING AT THIS POINT OYSTER
 LX3919'SHELLS WERE FOUND AT A DEPTH OF ABOUT 12 INCHES BELOW THE
 LX3919'SURFACE AND AT ABOUT 18 INCHES BELOW THE SURFACE A CAST IRON
 LX3919'HOLLOW CIRCULAR TRUNCATED CONE WAS UNCOVERED.  THE DIMENSIONS OF
 LX3919'THE CONE ARE HEIGHT, 5 INCHES.  TOP INSIDE DIAMETER, 5-1/4
 LX3919'INCHES.  BOTTOM INSIDE DIAMETER, 4-1/4 INCHES.  OUTSIDE DIAMETER
 LX3919'AT TOP INCLUDING FLANGE, 8-1/2 INCHES.  THICKNESS OF MATERIAL, 3/8
 LX3919'INCH.  THIS CONE WAS INSIDE A PIECE OF 15-INCH TILE
 LX3919'PIPE WITH NO BELL AND WAS FILLED WITH OYSTER SHELLS.  THERE WAS
 LX3919'NO EVIDENCE OF CEMENT.  THE REMAINS OF A STAKE (2 INCHES LONG
 LX3919'AND 1/2 INCH IN DIAMETER) WITH A TACK WERE FOUND FIRMLY EMBEDDED
 LX3919'IN THE OYSTER SHELLS.  BEFORE REMOVING THESE THE LOCATION OF
 LX3919'THE TACK WAS CROSS REFERENCED AND BOTH AN UNDERGROUND STATION
 LX3919'MARK 7A AND A SURFACE STATION MARK 1A WERE SET.  THE DISK WAS
 LX3919'MARKED ROUND HILL - 1866 - 1936.  AS FURTHER EVIDENCE THAT
 LX3919'THIS WAS THE ORIGINAL ROUND HILL THE REMAINS OF THE WALLS,
 LX3919'MENTIONED IN THE DESCRIPTION OF 1882, WERE FOUND AND THE
 LX3919'DISTANCES MEASURED FROM THEM TO THE STATION CHECKED
 LX3919'SUBSTANTIALLY WITH THOSE OF THE DESCRIPTION.  FURTHERMORE
 LX3919'TWO DIFFERENT TRAVERSES WERE RUN FROM THIS STATION TO STATION
 LX3919'ZIEGLER AND THEY BOTH CHECKED WITH AN ERROR IN POSITION OF
 LX3919'ABOUT 1 IN 15,000.  THE TOP OF THE HILL IS NOW COVERED WITH
 LX3919'GRASS AND MAY BE REACHED WITH AN AUTOMOBILE FROM JOHN
 LX3919'STREET AT ABOUT 1/4 MILE W OF THE INTERSECTION OF JOHN
 LX3919'STREET, AND ROUND HILL ROAD, THE MAIN ROAD FROM GREENWICH.

 LX3922'FROM THE OLD STATION ON THE HIGHEST PART OF THE GENTLY ROUNDED HILL
 LX3922'UPON WHICH THIS STATION WAS ORIGINALLY LOCATED, A SPOT 101 FEET
 LX3922'ALMOST DUE W (87 DEG 46 MIN TRUE) WAS SELECTED AS BEING FAR ENOUGH
 LX3922'REMOVED TO BE CLEAR OF CONSTRUCTION WORK NOW UNDER WAY BY THE
 LX3922'OWNER OF THE PROPERTY, DR. CHARLES V. PATERNO OF GREENWICH,
 LX3922'CONNECTICUT.  OLD STATION WILL BE UNDER POSITION OF LARGE
 LX3922'FIREPLACE IN HOUSE TO BE ERECTED, NEW STATION WILL BE IN YARD
 LX3922'BEYOND W WING OF HOUSE AND WITHIN CIRCULAR WALLED ENCLOSURE
 LX3922'AROUND HOUSE WHICH WILL HAVE AN APPROXIMATE RADIUS OF SOME 200
 LX3922'FEET.
 LX3922'
 LX3922'STATION IS A STANDARD DISK MARKED ROUND HILL 2 1937 SET FLUSH
 LX3922'IN TOP OF CONCRETE MONUMENT ROUNDED SOMEWHAT ON TOP AND EVEN WITH
 LX3922'LEVEL OF GROUND.  THIS MONUMENT TAKES THE FORM OF THE GROUND IN A
 LX3922'HOLE DUG ABOUT 30 INCHES DEEP AND 12 TO 15 INCHES IN DIAMETER.  A
 LX3922'SUB-SURFACE MARK SIMILAR TO THE STATION MARK WAS SET IN A PADDY
 LX3922'OF CEMENT BELOW, AND SEPARATED FROM THE STATION MONUMENT.
 LX3922'
 LX3922'THE MARK OF THE U.S. ENGINEERS (FIRE CONTROL) LOCATED 14.83
 LX3922'FEET FROM THE OLD STATION IS IN LINE OF EXCAVATION AND WILL BE
 LX3922'DESTROYED.
 LX3922'
 LX3922'TWO REFERENCE MARKS WERE SET, SIMILAR IN SIZE AND CHARACTER TO
 LX3922'THE STATION, WITH ARROWS POINTING TO THE STATION AND STAMPED ROUND
 LX3922'HILL 2 1937, NO.1 AND NO.2 RESPECTIVELY.  DISTANCES USED ARE
 LX3922'COMPUTED ONES (CHECKED CLOSELY BY ACTUAL TAPING) OBTAINED BY
 LX3922'TRIANGULATING BETWEEN THE MARKS.  DISTANCE BETWEEN ROUND HILL 2
 LX3922'AND REFERENCE MARK NO.1 USED AS BASE, AS SAME ARE OF EQUAL
 LX3922'ELEVATION.
 LX3922'
 LX3922'REFERENCE MARK NO.1 IS SET SXE FROM THE STATION, ALSO WITHIN
 LX3922'THE WALLED ENCLOSURE AND IN GROUND OF ABOUT THE SAME ELEVATION.

 LX7610
 LX7610.The horizontal coordinates were established by GPS observations
 LX7610.and adjusted by the National Geodetic Survey in June 2012.
 LX7610
 LX7610.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 LX7610.been affixed to the stable North American tectonic plate. See 
 LX7610.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 LX7610
 LX7610.The horizontal coordinates are valid at the epoch date displayed above
 LX7610.which is a decimal equivalence of Year/Month/Day.
 LX7610
 LX7610.The orthometric height was determined by GPS observations and a
 LX7610.high-resolution geoid model.
 LX7610
 LX7610.GPS derived orthometric heights for airport stations designated as
 LX7610.PACS or SACS are published to 2 decimal places.  This maintains
 LX7610.centimeter relative accuracy between the PACS and SACS.  It does
 LX7610.not indicate centimeter accuracy relative to other marks which are
 LX7610.part of the published vertical control network.
 LX7610
 LX7610.Significant digits in the geoid height do not necessarily reflect accuracy.
 LX7610.GEOID18 height accuracy estimate available here.

 LX7610.Click photographs - Photos may exist for this station.
 LX7610
 LX7610.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 LX7610
 LX7610.The Laplace correction was computed from DEFLEC18 derived deflections.
 LX7610
 LX7610.The ellipsoidal height was determined by GPS observations
 LX7610.and is referenced to NAD 83.

 LX3772'A NEW DESCRIPTION IS RECOMMENDED AS FOLLOWS--STATION LOCATED ON
 LX3772'SHERWOOD POINT ABOUT 2 MILES E OF TOWN OF SAUGATUCK, AT THE WEST
 LX3772'END OF ALVORD BEACH.  THE STATION IS SET ABOUT IN THE CENTER OF
 LX3772'A CONCAVE TOP BOULDER, ABOUT 10X6 FEET IN SIZE, AND IS ABOUT
 LX3772'2 FEET ABOVE HIGH WATER AND ABOUT 100 FEET N OF THE H.W.L.
 LX3772'STATION MARK IS THE CENTER OF THE SHANK OF A STANDARD BRONZE DISK
 LX3772'WEDGED IN A DRILL HOLE IN BOULDER.  CIRCULAR TOP OF DISK
 LX3772'IS GONE.  TOP OF SHANK IS ABOUT 1/2 INCH ABOVE BOULDER AND
 LX3772'IS COVERED WITH A CIRCLE OF RED PAINT, WITH 361 PAINTED IN RED ON
 LX3772'EAST FACE OF BOULDER.  A PROMINENT BOULDER ABOUT 100 FEET OFFSHORE
 LX3772'IS A GUIDE IN FINDING STATION MARK.  IT IS ABOUT 90 FEET SSE OF A
 LX3772'WILD CHERRY TREE AT THE GRASS AND SAND LINE AT SOUTHERN
 LX3772'EXTREMITY OF SHERWOOD POINT.  THE ENTIRE AREA IS NOW KNOWN AS
 LX3772'SHERWOOD ISLAND STATE PARK AND IS EASILY REACHED AND WELL MARKED
 LX3772'FROM THE NEW CONNECTICUT TURNPIKE.
 LX3772'
 LX3772'R.M. 1 IS NOT RECOVERED.  DUG DOWN 4 OR 5 INCHES BUT COULD NOT
 LX3772'FIND.  BOULDERS ARE UNDER BEACH SAND.  R.M. 2 IS RECOVERED IN FAIR
 LX3772'CONDITION AS IF BADLY WORN BY HEAVY ROCKS IN STORMS.  BOTTOM OF
 LX3772'DISK IS ABOUT 1/4 INCH ABOVE TOP OF ITS BOULDER.  DISTANCES AND
 LX3772'DIRECTION CHECKS FROM STATION.

 LX3772'HAVING HEARD THAT THERE WAS EXTENSIVE CONSTRUCTION GOING ON, IN
 LX3772'THIS AREA, I VISITED HERE TODAY.  A LARGE MODERN PAVILLION, ABOUT
 LX3772'100 YDS N OF SHERWOOD PT., IS NEARLY COMPLETED.  EXTENSIVE GRADING,
 LX3772'BULLDOZING, NEW ROADS, AND SO ON, ARE UNDER CONSTRUCTION.  I WAS
 LX3772'AFRAID THE STATION MIGHT BE DISTURBED.  SAW AN ENGINEER
 LX3772'LEVELING.  BUT STATION IS O.K.  RED CIRCLE IN 1959 IS NOW A
 LX3772'YELLOW CIRCLE (INDICATING USE).  ALSO 361 IS GONE, PROBABLY FROM
 LX3772'HEAVY STORMS.  R.M. 2 IS BEAT UP, TOP 1/3RD OF DISK, TOWARD
 LX3772'STATION IS GONE, BUT ARROW IS VISIBLE.
 LX3772'
 LX3772'R.M. 1 IS I BELIEVE, GONE.
 LX3772'
 LX3772'DISTANCE FROM STATION TO 2-PRONG WILD CHERRY TREE TO NW IS ABOUT
 LX3772'115 FT. -- NOT 90 FT. AS REPORTED IN MY 1/29/59 REPORT.  NO CHANGE
 LX3772'IN LOCATION OF STATION OR TREE.  I MUST HAVE ESTIMATED ABOUT 90
 LX3772'FT. IN 1959.  TODAY, WITHOUT TAPE, I CAREFULLY PACED THIS
 LX3772'DISTANCE, WHICH MEANS IT IS STILL ONLY AN APPROXIMATE DISTANCE.

 LX7047
 LX7047'DESCRIBED BY COAST AND GEODETIC SURVEY 1891 (WCH)
 LX7047'ON A BARE HILL IN ROCKY HILL CENTER, 8 MILES FROM HARTFORD.  THE
 LX7047'HILL IS KNOWN AS SHIPMANS HILL AND IS THE PROPERTY OF THE WIDOW
 LX7047'AND CHILDREN OF SAMUEL SHIPMAN.  THE STATION IS ABOUT 1/4 MILE
 LX7047'FROM THE RIVER AND 1/2 MILE N OF THE CONNECTICUT VALLEY
 LX7047'RAILROAD STATION.  SHIPMANS HOUSE IS ON THE TURNPIKE AT THE
 LX7047'FOOT OF THE HILL, W OF THE STATION.  AFTER DIGGING 1 FOOT
 LX7047'BENEATH THE STATION A LEDGE WAS STRUCK.  THE ROCK WAS HARD AND
 LX7047'WHEN DRILLED BROKE IRREGULARLY.  A RATHER SCRAGGY HOLE 1-1/2
 LX7047'INCHES DEEP WAS SECURED AND THIS MARKS THE STATION.  FROM THE
 LX7047'STATION TO A TRIANGLE ON A LARGE ROCK TO E IS 16 FEET.  TO
 LX7047'LARGE ROCK NW, 2 FEET 10-1/2 INCHES.  IN 1891 THE STATION
 LX7047'WAS RECOVERED WITH SOME DIFFICULTY, AND A LARGE PILE OF
 LX7047'STONES WAS LEFT OVER IT TO AID IN FUTURE RECOVERIES.

 LX6775'STATION IS ON A BARE HILL KNOWN AS CHESTNUT HILL, IN S
 LX6775'GLASTONBURY.  IT COMMANDS A FINE VIEW OF THE RIVER AND ADJACENT
 LX6775'TERRITORY.  HILL MAY BE IDENTIFIED BY A SINGLE ROW OF APPLE TREES
 LX6775'ON ITS VERY TOP, RUNNING N AND S.  IT IS THE PROPERTY OF FRANK
 LX6775'TAYLOR WHOSE RESIDENCE IS ON THE TURNPIKE A SHORT DISTANCE ABOVE
 LX6775'S GLASTONBURY.  MARKED BY A DRILL HOLE IN A ROCK BURIED ABOUT 2
 LX6775'FEET BELOW SURFACE OF GROUND.  DISTANCE FROM STATION TO STUB
 LX6775'WITH COPPER TACK, NE 65 FEET 1 INCH.  TO ANOTHER STUB WITH
 LX6775'COPPER TACK, W 87 FEET 4 INCHES.  IN 1891 THE STATION WAS
 LX6775'RECOVERED ONLY AFTER A LONG SEARCH.  THE HILL AND THE APPROXIMATE
 LX6775'LOCATION OF THE STATION WERE EASILY IDENTIFIED, BUT THE REFERENCE
 LX6775'STUBS HAD DISAPPEARED, AND THE DIGGING WAS DIFFICULT.  TO
 LX6775'FACILITATE THE FUTURE RECOVERY OF THE STATION THE FOLLOWING
 LX6775'REFERENCES WERE MADE TO APPLE TREES IN A SINGLE ROW RUNNING N AND
 LX6775'S AND PASSING JUST E OF THE STATION.  TO NAIL IN TENTH APPLE TREE
 LX6775'FROM S END, 64.23 FEET.  TO NAIL IN NINTH APPLE TREE, 39.83 FEET.
 LX6775'TO NAIL IN EIGHTH APPLE TREE, 33.9 FEET.  TO NAIL IN
 LX6775'SEVENTH APPLE TREE, 55.0 FEET.  DISTANCE TO CHESTNUT TREE ON
 LX6775'W SLOPE OF HILL, 188.35 FEET, TO FENCE IN LINE TO CHESTNUT TREE,
 LX6775'89.0 FEET.  TO N END OF FIELD, 472.5 FEET.  TO S END OF FIELD,
 LX6775'294.3 FEET.  A MOUND OF EARTH WAS THROWN UP OVER THE CENTER
 LX6775'MARK.  THE LAND AT THE STATION BELONGED IN 1891 TO NOEL H.

 LX3823'RECOVERED STATION AND TWO R.M.S, AS DESCRIBED, IN VERY GOOD CONDITION,
 LX3823'WITH THE FOLLOWING COMMENTS--IMPORTANT.  STATION IS ON THE HIGHEST
 LX3823'ELEVATION WHICH IS NEAR THE SW PORTION OF THE TIMBERED HILLTOP.
 LX3823'CENTRAL PART OF TOP OF THE NEARLY-LEVEL, SUMMIT AREA IS ABOUT 4 FT.
 LX3823'LOWER THAN THE STATION ELEVATION.
 LX3823'
 LX3823'SAW NO 10 IN MAPLE TREE, TRIANGULAR-BLAZED, 13 FT. E OF STATION BRONZE
 LX3823'DISK.  INSTEAD, AT 12.5 FT. E OF STATION, THERE ARE TWO DEAD, VERTICAL
 LX3823'TREES TOUCHING EACH OTHER AT GROUND LEVEL.  THE LEFT HAND (NLY) TREE
 LX3823'IS ABOUT 20 FT. HIGH, AND HAS FOUR OLD DRILLED (OR WOODPECKER) 3/8
 LX3823'INCH DIAM. HOLES FACING THE STATION.  THE RIGHT HAND (SLY) TREE, SAME
 LX3823'DIAMETER, IS ONLY A ROTTED STUMP, 3 FT. HIGH, AND HAS TWO SIMILAR
 LX3823'HOLES, FACING THE STATION.  NO OTHER TREES WITH DRILL HOLES SEEN IN
 LX3823'THIS VICINITY.  NOR WAS ANY BLAZED TREE SEEN IN THE STATION AREA.

 LX3823'YEARS LEAVES, BUT A 1 IN. TO 3 IN. UNDERLAYER OF OLDER, DECAYED, DAMP
 LX3823'LEAVES.
 LX3823'
 LX3823'BY BEARING AND DISTANCE FROM R.M.2, FOUND STATION.  AND THEN, R.M.1.
 LX3823'
 LX3823'STONE NESTS NOTED ABOVE, ARE COVERED WITH LEAF DEPOSITS, AND WERE NOT
 LX3823'PERCEIVED UNTIL R.M.2 AND STATION WERE FOUND.
 LX3823'
 LX3823'I LEFT ALL THREE SUMMIT DISKS UNCOVERED AND SWEPT CLEAN.  NO SIGNS OF
 LX3823'ANY PREVIOUS VANDALISM.  IM SURE NO PERSON HAS BEEN HERE FOR YEARS.
 LX3823'NOR WAS THERE ANY TRACE OF DEER PATHS OR ANIMAL TRAILS.
 LX3823'
 LX3823'ALTHOUGH AZ. MARK WAS NOT SPOT-CHECKED, 4/5/65, I STOPPED AT POLE GATE
 LX3823'ON RIGHT, 0.3 MILE S OF SHINGLED HOUSE, LOOKED 63 FT. NW ACROSS

 LX6484
 LX6484'DESCRIBED BY COAST AND GEODETIC SURVEY 1921 (IW)
 LX6484'THIS STATION WAS ESTABLISHED IN MAY, 1921, TO TAKE THE PLACE OF
 LX6484'WEST ROCK 2, WHICH THE PARK IMPROVEMENT WILL DESTROY.  IT IS
 LX6484'SITUATED IN WEST ROCK PARK, NEW HAVEN, CLOSE TO THE ALMOST
 LX6484'PERPENDICULAR FACE OF WEST ROCK, JUST OUTSIDE THE WALL AROUND
 LX6484'THE PLAZA AT THE TOP OF THE ROCK OUTSIDE THE DRIVEWAY.  IT IS
 LX6484'ON A BARE LEDGE OF TRAP ROCK AND IS MARKED BY A STANDARD
 LX6484'TRIANGULATION MARK WEDGED IN AN INCH HOLE DRILLED IN THE ROCK.
 LX6484'A STANDARD REFERENCE MARK WAS WEDGED IN AN INCH HOLE IN ANOTHER
 LX6484'BARE LEDGE ABOUT 3 FEET LOWER AND 25 FEET DISTANT FROM THE
 LX6484'STATION.  THE STATION CAN BE REACHED BY FOLLOWING THE
 LX6484'DRIVEWAY TO WEST ROCK PARK AND THENCE THROUGH THE PARK TO THE
 LX6484'TOP OF WEST ROCK.

 LX6484
 LX6484'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1933 (GCM)
 LX6484'THIS STATION IS LOCATED ON THE SOUTHEASTERLY EXTREMITY OF WEST
 LX6484'ROCK, A PART OF THE PARK SYSTEM OF THE CITY OF NEW HAVEN.
 LX6484'
 LX6484'STATION AND REFERENCE MARKS ARE STANDARD BRONZE DISK SET IN
 LX6484'OUTCROPPING BEDROCK AS DESCRIBED IN NOTES 2, AND 12A.
 LX6484'
 LX6484'TO APPROACH FROM NEW HAVEN--GO W ON WHALLEY AVENUE TO BLAKE
 LX6484'STREET.  TURN RIGHT AND GO 0.7 MILE TO SPRINGSIDE AVENUE, TURN
 LX6484'RIGHT AND GO 1.4 MILES TO A POINT JUST BEYOND THE CITY
 LX6484'ALMSHOUSE.  THIS POINT MARKS THE BEGINNING OF THE AUTOMOBILE
 LX6484'ROAD TO THE SUMMIT.  TURN LEFT AND GO 1.5 MILES TO THE PARKING
 LX6484'PLACE OF THE S SUMMIT.
 LX6484'
 LX6484'THE STATION IS ON THE OUTCROPPING LEDGE A LITTLE BELOW THE
 LX6484'WALL SURROUNDING THE PARKING PLACE AND 5.3 METERS FROM THIS
 LX6484'WALL.  IT IS ABOUT 10 METERS BACK FROM THE VERTICAL FACE OF THE
 LX6484'CLIFF.  STATION IS 25.6 METERS FROM THE EASTERLY STEPS THROUGH
 LX6484'THE WALL, THE LOWER END OF THE STEPS BEARING N 55 DEG E
 LX6484'(MAGNETIC).
 LX6484'
 LX6484'REFERENCE MARK IS IN A CONTINUATION OF THE LEDGE BEARING THE
 LX6484'STATION.  IT BEARS S 50 DEG E (MAGNETIC) AND IS 7.76 METERS
 LX6484'DISTANT.
 LX6484'
 LX6484'BOTH CENTER AND REFERENCE MARKS REMAIN AS ESTABLISHED IN 1921.

 LX6484                          STATION RECOVERY (1967)
 LX6484
 LX6484'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1967 (CHO)
 LX6484'RECOVERED STATION, R. M., AND LOWER END OF STEPS, AS DESCRIBED
 LX6484'BY G.C.M. 33.  ALL IN GOOD CONDITION.  TOP OF STATION DISK
 LX6484'HAS A FEW SLIGHT SURFACE DENTS, BUT IS ENTIRELY IN USEFUL
 LX6484'CONDITION.  SURROUNDING, AND TOUCHING, THIS DISK, IS A ONE INCH,
 LX6484'CIRCULAR BAND OF WHITE PAINT, ON THE LEDGE.  EXTENDING OUTWARD
 LX6484'FROM THE WHITE CIRCLE, ARE FOUR WHITE-PAINT LINES, 2 FT. LONG
 LX6484'AND 2 INCHES WIDE, 90 DEGREES APART.  SEEN FROM ABOVE, THIS IS
 LX6484'A PROMINENT WHITE CROSS.
 LX6484'
 LX6484'BECAUSE OF CHANGES IN STREET NAMES, SOME RENUMBERING, AND
 LX6484'EXTENSION OF OLDER STREETS, G.C.M.S 1933 TO APPROACH IS NO
 LX6484'LONGER CORRECT.  CHANGE HIS THIRD PARAGRAPH TO READ--TO APPROACH
 LX6484'FROM NEW HAVEN, GO WNW ON WHALLEY AVENUE TO BLAKE STREET.  TURN
 LX6484'RIGHT (E) AND GO 0.3 MILE TO SPRINGSIDE AVENUE (4TH STREET E
 LX6484'FROM WHALLEY) (AT 37 BLAKE).  TURN LEFT AND GO NLY ON SPRINGSIDE
 LX6484'FOR 1.10 MILE TO LARGE, NEW, BRICK BUILDING, WITH TWO TALL
 LX6484'FLAGPOLES, AND A SIGN, NEW HAVEN REGIONAL CENTER, STATE
 LX6484'DEPARTMENT OF HEALTH, AT CORNER OF SPRINGSIDE AND WINTERGREEN
 LX6484'AVENUES.  CONTINUE NLY 0.15 MILE TO BRUCE RITTER MAIL
 LX6484'BOX AND BROWN COTTAGE AT 1138 SPRINGSIDE AVENUE.
 LX6484'
 LX6484'DISTANCE FROM BLAKE ST. TO RITTERS IS 1.25 MILE
 LX6484'
 LX6484'OPPOSITE RITTERS IS THE BEGINNING OF AUTOMOBILE ROAD TO THE
 LX6484'SUMMIT.
 LX6484'
 LX6484'TAKE LEFT FORK AT RITTERS AND GO NW FOR 0.1 MILE.  HERE, TAKE
 LX6484'HAIRPIN LEFT TURN, WHICH SHORTLY CURVES TO THE RIGHT, AND WINDS
 LX6484'ITS WAY SLY TO THE SUMMIT.  DISTANCE FROM RITTERS TO SUMMIT
 LX6484'IS 1.45 MILE.  SUMMIT ROAD NEEDS SOME BLACK-TOP PATCHING, BUT
 LX6484'IS FAIRLY GOOD.
 LX6484'
 LX6484'REMAINING PARAGRAPHS OF G.C.M. 1933 REPORT WERE CAREFULLY
 LX6484'CHECKED.  SKETCH IS VERY GOOD.
 LX6484'
 LX6484'NOTE--G.C.M.S ALMSHOUSE NOT SEEN 5/5/67.  VISITED NEW HAVEN
 LX6484'CITY ENGINEERS OFFICES, 5/11/67.  ASSISTANT ENGINEER CY BAYUK
 LX6484'SHOWED ME LARGE MAP OF PRESENT STREETS IN WEST ROCK AREA.  LATER, I
 LX6484'RECHECKED TO APPROACH DISTANCES, GIVEN ABOVE.  AND ALSO FOUND
 LX6484'THE ALMSHOUSE, ON ITS ORIGINAL FOUNDATION.
 LX6484'
 LX6484'IT IS NOW PARTLY HIDDEN BY TREES, AND IS ON NE SIDE OF
 LX6484'WINTERGREEN AVENUE, 0.1 MILE SE OF CORNER OF SPRINGSIDE AND
 LX6484'WINTERGREEN.
 LX6484'
 LX6484'G.C.M.S TO A POINT JUST BEYOND THE CITY ALMSHOUSE WAS CORRECT
 LX6484'AND HELPFUL, BEFORE STREET CHANGES, AND TREE CAMOUFLAGE.  NOW THE
 LX6484'FLAG-FLYING HEALTH CENTER (NOTED ABOVE) IS A BETTER CHECK-POINT.
 LX6484'
 LX6484'5/5/67, AFTER RECOVERING STATION, I RETURNED TO RITTERS, 1138
 LX6484'SPRINGSIDE AVENUE.  THEN, AGAIN TOOK SUMMIT ROAD 0.1 MILE TO
 LX6484'START OF HAIRPIN LEFT TURN.  BUT, THIS TIME, I TURNED RIGHT ON
 LX6484'A GOOD, WIDE BLACK-TOP ROAD (NO NAME-SIGN) WHICH LEADS N OVER
 LX6484'THE WILBUR CROSS PARKWAY TUNNEL AND CONTINUES NLY ALONG THE
 LX6484'WOODED RIDGE -- AWAY FROM THE STATION.  I HOPED TO SEE A
 LX6484'FOOTPATH SIGN, TO JUDGES CAVE (A HIDEOUT IN COLONIAL DAYS), BUT
 LX6484'SAW NO SIGN -- ONLY GOOD SCENERY.  CONTINUED NLY FOR FOUR
 LX6484'MILES ALONG WOODED RIDGE.  THEN, TURNED BACK TO RITTERS, AND
 LX6484'TO NEW HAVEN AND DARIEN.
 LX6484'
 LX6484'PERSONAL NOTE (NOT FOR INCLUSION IN THIS 1967 RECOVERY
 LX6484'REPORT).  NATURAL, OR MAN-MADE, CHANGES NECESSITATE CHANGES IN TO
 LX6484'APPROACH DIRECTIONS IN OLDER REPORTS.  NOTHING IN THIS REPORT
 LX6484'SHOULD BE CONSIDERED AS ADVERSE CRITICISM OF GEORGE C. MATTISON
 LX6484'(GCM).  WE FIRST MET IN THE PHILIPPINES, ABOUT 1915.  LATER, AFTER
 LX6484'WORLD WAR I, HE RELIEVED ME OF MY ONE-YEAR COMMAND OF THE
 LX6484'OLD HYDROGRAPHER IN KEY WEST.  WE VE BEEN FRIENDS OVER
 LX6484'THE YEARS -- VISITED HIM IN MOBILE AFTER HIS RETIREMENT.

 LX6484
 LX6484'RECOVERY NOTE BY US POWER SQUADRON 1984 (DJP)
 LX6484'THE SURVEY MARK WAS RECOVERED IN GOOD CONDITION WITH A FEW SURFACE
 LX6484'DENTS, BUT USEABLE.  THE DESCRIPTION IS ADEQUATE, BUT THE PARK IS
 LX6484'NO LONGER PART OF THE NEW HAVEN PARK SYSTEM.  IT IS CONTROLLED BY
 LX6484'THE STATE OF CONN. AND THE ENTRANCE IS CLOSED OFF DUE TO VANDALISM.
 LX6484'THE KEY FOR THE GATE MAY BE OBTAINED FROM THE PARK RANGER WHO IS
 LX6484'LOCATED AT THE NATURE CENTER ON WINTERGREEN AVE.

 LX3817
 LX3817'DESCRIBED BY COAST SURVEY (CGS) 1864 (ADB)
 LX3817'ON THE SUMMIT OF WOOSTER MOUNTAIN, A WOODED SUMMIT LOCALLY KNOW AS
 LX3817'PINE HILL, LYING IN THE NORTHEASTERN PART OF THE TOWN OF RIDGEFIELD,
 LX3817'3-1/2 MILES SOUTHWESTERLY FROM DANBURY (CENTER)  AND 2 MILES SE OF
 LX3817'RIDGEBURY VILLAGE.  IT MAY BE REACHED FROM A SCHOOLHOUSE IN A FORK IN
 LX3817'THE ROAD 1.2 MILES DUE N OF STATION, BY FOLLOWING THE DANBURY ROAD
 LX3817'SOUTHEASTERLY 400 FEET, THENCE SW AND SE PASSING F.  WEINDOOFS
 LX3817'FARMHOUSE AND FOLLOWING A LANE ABOUT 100 FEET THEN TURNING SOUTHERLY
 LX3817'OUT OF THE LANE, FOLLOW A WOODS ROAD ABOUT 1 MILE TO A POINT 150 FEET
 LX3817'E OF THE STATION.  THERE IS A FAIR VIEW TO THE W, BUT TREES OBSTRUCT
 LX3817'IN OTHER DIRECTIONS.  STATION MARK IS A COPPER BOLT WITH CROSS CUT IN
 LX3817'TOP SET FLUSH IN A DRILL HOLE MADE IN A CREVICE IN THE LEDGE 11-1/2
 LX3817'FEET S 65 DEG E (MAGNETIC) FROM AND ABOUT 1-1/4 FEET BELOW THE HIGHEST
 LX3817'POINT OF A PROMINENT OUTCROP WHICH ITSELF FORMS THE EXACT SUMMIT OF
 LX3817'THE HILL.

 LX3817'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1932 (JRC)
 LX3817'FIRST PARAGRAPH STILL GOOD.
 LX3817'
 LX3817'IT MAY BE REACHED FROM THE STATE ARMORY IN DANBURY BY PROCEEDING
 LX3817'TOWARDS RIDGEBURY 3.5 MILES TO NORRIS CORNER AT THE DANBURY RIDGEFIELD
 LX3817'LINE.  TURN S AND FOLLOW AN UNIMPROVED ROAD 0.9 MILE TO A STONE HOUSE
 LX3817'FROM WHICH POINT THE STATION IS S 60 DEG E ABOUT 1000 YARDS AND
 LX3817'REACHED BY FOLLOWING A WOODS ROAD LEADING TOWARDS THE CONSPICUOUS PINE
 LX3817'MOUNTAIN.
 LX3817'
 LX3817'DURING 1932 A 20-FOOT TOWER AND A BARREL AT A STILL FURTHER HEIGHT OF
 LX3817'10 FEET WERE PLACED BY NATIONAL GUARD OFFICERS.

 LX3817
 LX3817'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1942 (KBJ)
 LX3817'THE STATION MARK WAS RECOVERED AS DESCRIBED.  IT IS MARKED BY A CROSS
 LX3817'AT THE TOP OF A COPPER BOLT.  THE BOLT HAS BEEN GIVEN PROTECTION BY
 LX3817'CONCRETE WHICH SURROUNDS IT LEAVING A SPACE SO THAT IT IS STILL
 LX3817'VISIBLE.  THIS CONCRETE PROJECTS ABOUT 3 INCHES ABOVE THE TOP OF THE
 LX3817'BOLT.
 LX3817'
 LX3817'THREE REFERENCE MARKS WERE ESTABLISHED IN 1938, AS DESCRIBED BELOW--
 LX3817'
 LX3817'REFERENCE MARK NO.1 IS 41.483 METERS, 136.10 FEET, NNE OF THE STATION.
 LX3817'THE DISK IS SET IN A DRILL HOLE IN A BOULDER AND IS STAMPED WOOSTER
 LX3817'NO.1 1938.  NOTE 12C.
 LX3817'
 LX3817'REFERENCE MARK NO.2 IS 40.332 METERS, 132.32 FEET, E OF THE STATION.
 LX3817'THE DISK IS SET IN A DRILL HOLE IN A BOULDER AND IS STAMPED WOOSTER
 LX3817'NO.2 1938.  NOTE 12C.
 LX3817'
 LX3817'REFERENCE MARK NO.3 IS 43.665 METERS, 143.26 FEET, WNW OF THE STATION.
 LX3817'THE DISK IS SET IN A DRILL HOLE AT THE S END OF A LARGE BOULDER ABOUT
 LX3817'10 FEET HIGH AND 30 FEET IN LENGTH.  THE DISK IS STAMPED WOOSTER NO.3
 LX3817'1938.  NOTE 12C.
 LX3817'
 LX3817'NO SUITABLE SITE WAS AVAILABLE FOR AN AZIMUTH MARK.
 LX3817'
 LX3817'TO REACH THE STATION FROM THE JUNCTION OF U.S. HIGHWAY 6 AND U.S.
 LX3817'HIGHWAY 7 AT THE W EDGE OF DANBURY, GO S FOR 0.1 MILE TO PARK AVENUE,
 LX3817'TURN RIGHT AND FOLLOW PARK AVENUE AND U.S. HIGHWAY 7 W FOR 1.95 MILES
 LX3817'TO A CROSS ROAD JUST AFTER PASSING AN ESSO SERVICE STATION, TURN RIGHT
 LX3817'AND GO 0.25 MILE TO A FORKS, KEEP THE RIGHT FORK AND THEN GO 1.0 MILE
 LX3817'TO ANOTHER FORKS, THEN TAKE THE LEFT FORK AND GO 0.55 MILE TO A SIDE
 LX3817'ROAD LEFT JUST AFTER CROSSING A BRIDGE OVER A SMALL STREAM, TURN LEFT,
 LX3817'S, ON THE GRAVEL AND GO 0.7 MILE TO A FORKS, TAKE THE LEFT FORK AND GO
 LX3817'0.15 MILE TO A STONE HOUSE, PASS AROUND THE HOUSE ON THE LEFT AND GO
 LX3817'UP A STEEP GRADE FOR ABOUT 0.1 MILE TO WHERE THE ROAD BENDS RIGHT AT A
 LX3817'SMALL STREAM.  IN WET WEATHER IT IS NOT ADVISABLE TO CONTINUE BEYOND
 LX3817'THIS POINT BY TRUCK.  FROM THE STREAM FOLLOW THE WOODS ROAD KEEPING
 LX3817'UPGRADE AT SEVERAL DIM FORKS FOR 0.5 MILE TO THE TOP OF THE HILL AND
 LX3817'STATION.
 LX3817
 LX3817                          STATION RECOVERY (1964)
 LX3817
 LX3817'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1964 (CHO)
 LX3817'RECOVERED ESSENTIALLY AS DESCRIBED BY K.B.J., 1942.  CROSS AT TOP OF
 LX3817'THE COPPER BOLT AND THE BOLT ITSELF ARE NO LONGER VISIBLE.  TODAY,
 LX3817'THERE IS AN IRREGULAR CIRCLE OF CONCRETE ABOUT FOUR FEET IN DIAMETER.
 LX3817'IN THE APPROX. CENTER OF THIS IS A PIECE OF QUARTZ WHICH PROTRUDES
 LX3817'ABOUT 1/4 INCH ABOVE THE CONCRETE SURFACE.  I BELIEVE THAT, SINCE
 LX3817'1942, NEWER CONCRETE WAS PLACED HERE, AND THAT, JUST BEFORE IT SET,
 LX3817'THE QUARTZ WAS PLACED OVER THE BOLT, AND SMOOTHED OVER FOR A FINAL
 LX3817'SETTING, AS IT APPEARS TODAY.  K.B.J.S VISIBILITY SPACE IS NO LONGER
 LX3817'HERE.  I TRIED WITH A SHARP KNIFE TO DISLODGE THE SMALL PIECE OF
 LX3817'QUARTZ (ABOUT 3/4 INCH ACROSS) BUT IT WAS HARDER THAN MY BLADE.  I
 LX3817'THINK A SHARP COLD CHISEL COULD REMOVE THE ADJOINING CONCRETE, AND
 LX3817'DISCLOSE THE BOLT UNDERNEATH THE QUARTZ.
 LX3817'
 LX3817'THIS IS NOT THEORY, BECAUSE DIRECTIONS AND SLOPE-DISTANCES TO THE
 LX3817'THREE R.M.S CHECKED VERY CLOSELY.  ALSO THE QUARTZ IS APPROX. MIDWAY
 LX3817'BETWEEN THREE SQUARE, CONCRETE FOUNDATIONS, EACH ABOUT 2-1/2 FT.
 LX3817'SQUARE, AND RANGING IN HEIGHT ABOVE ROCK BASE FROM 20 IN, 29 IN, AND 3
 LX3817'FT 7-1/2 IN.  EACH FOUNDATION HAS FOUR THREADED BOLTS EXTENDING
 LX3817'UPWARD, AND EACH BOLT CARRIES A RUSTY NUT, EXCEPT THAT THE SW
 LX3817'FOUNDATION HAS ONLY 3 NUTS.  DISTANCES BETWEEN CENTERS OF FOUNDATIONS
 LX3817'IS ABOUT 17 FEET.  IN THE TOP OF THE SW FOUNDATION IS F. RAINER AND R
 LX3817'S S WOOSTER AND THE INITIALS JHD AND THE DATE 3-21-1938--ALL DONE WITH
 LX3817'A SHARP INSTRUMENT, BEFORE THE CONCRETE HARDENED.  NOTE-IN MY 6/16/64
 LX3817'LETTER TO THE DIRECTOR, THIRD PARAGRAPH, IS I FOUND FOUR CONCRETE
 LX3817'SUPPORTS.  THE FOUR SHOULD HAVE BEEN THREE.  PRIOR TO MY 6/16/64
 LX3817'LETTER, I COULD FIND NO R.M.S, BUT TODAY I FOUND ALL THREE, AS
 LX3817'FOLLOWS-
 LX3817'
 LX3817'R.M. 1--RECOVERED AS DESCRIBED, IN VERY GOOD CONDITION, EXCEPT THAT
 LX3817'STAMPED DATE IS 1937.  TOP OF DISK IS TILTED SLIGHTLY DOWNWARD TOWARD
 LX3817'STATION, BUT IS SOLIDLY SECURE IN PLACE.
 LX3817'
 LX3817'R.M. 2--RECOVERED AS DESCRIBED, IN VERY GOOD CONDITION, BUT ITS
 LX3817'STAMPED DATE IS ALSO 1937.  ALSO, ITS BEARING FROM THE STATION IS E X
 LX3817'S--NOT E.
 LX3817'
 LX3817'R.M. 3--RECOVERED AS DESCRIBED, IN VERY GOOD CONDITION, BUT ITS
 LX3817'STAMPED DATE IS ALSO 1937.  UNDERSIDE OF DISK ON N TANGENT TO ITS
 LX3817'PERIPHERY HAS NO CEMENT, BUT FITS SNUGLY TO SURFACE OF BOULDER.  DISK
 LX3817'IS SOLIDLY SECURE.
 LX3817'
 LX3817'TOOK THREE COLOR SHOTS, AT THE STATION.  IF THEY ARE GOOD ILL FORWARD
 LX3817'THEM.  ALSO, ILL SEND A REVISED TO REACH DIRECTIONS.  K.B.J.S WAS THE
 LX3817'BEST AVAILABLE, BUT THERE ARE CHANGES IN APPROACH.
 LX3817'
 LX3817'I NEEDED 2 RECONNAISANCE TRIPS PLUS 4 TRIPS CLIMBING WOOSTER MTN. TO
 LX3817'BE SURE ID FOUND THE STATION.  GREATEST HELPS WERE COMPASS, USCGS
 LX3817'POCKET ANEROID, AND TAPE, PLUS A COMPARATIVE LACK OF FOLIAGE ON
 LX3817'DECIDUOUS TREES TODAY.  CLOSELY SPACED TREES ARE 8 IN TO 12 IN IN
 LX3817'DIAMETER, AND TRAILS ARE WINDING AND EXCEPTIONALLY DIM.  REALLY NEEDED
 LX3817'THE ANEROID TO BE SURE I REACHED THE TOP--RATHER RUGGED GOING.
 LX3817'
 LX3817'FROM CENTER OF DANBURY, GO W ON WEST ST., THEN S ON PARK AVE., WHICH
 LX3817'WINDS SWLY AND W TO THE E BOUNDARY OF THE DANBURY FAIR GROUNDS.  HERE,
 LX3817'TURN LEFT (S) ON ROUTE 7, AND CONTINUE S TO THE OVERHEAD TRAFFIC LIGHT
 LX3817'AT MIRY BROOK ROAD.  THIS JUNCTION ADJOINS THE SELY BOUNDARY OF THE
 LX3817'DANBURY AIRPORT.
 LX3817'
 LX3817'AGAIN, FROM NORWALK, OR THE MERRITT PARKWAY, TAKE ROUTE 7, HEADING
 LX3817'NLY, TO THE ABOVE SAME JUNCTION OF ROUTE 7 AND MIRY BROOK ROAD.
 LX3817'
 LX3817'HERE, TURN WLY ON MIRY BROOK ROAD, WHICH SKIRTS THE SN BOUNDARY OF THE
 LX3817'AIRPORT, AND CONTINUES SW, W, AND AGAIN SW.  USING THE ABOVE ROUTE 7
 LX3817'JUNCTION AS 0.0, PASS SUGAR HOLLOW RD. ON LEFT, AT 0.3.  PASS SPRUCE
 LX3817'MTN. RD. ON LEFT AT 0.6.  PASS BACKUS RD. ON RIGHT, AT 1.3.  PASS
 LX3817'WOOSTER SCHOOL ENTRANCE ON RIGHT, AT 1.4.  CROSS BRIDGE AND TURN LEFT
 LX3817'ON PINE MTN. RD., AT 1.80 ALL DISTANCES, STATUTE MILES, WLY FROM ROUTE
 LX3817'7.
 LX3817'
 LX3817'GO S ON PINE MTN. RD., 0.4 MILE TO RALPH MARSHS RED (FORMERLY WHITE)
 LX3817'HOUSE ON RIGHT.  ABOUT 8 YEARS AGO, HE CLIMBED PINE MTN., AND SAW
 LX3817'STATION WOOSTER.  HE GAVE ME ADVICE, BUT SOME OF THE APPROACH DETAILS
 LX3817'HAVE CHANGED SINCE HIS TRIP.  FROM MARSHS HOUSE, CONTINUE S FOR 0.3
 LX3817'MILE TO FOUR MAIL BOXES ON THE RIGHT.  HERE, PARK CAR ON E SIDE OF
 LX3817'PINE MTN. RD., EXCEPT IN VERY DRY WEATHER, AND WALK E, SLIGHTLY
 LX3817'UPHILL, FOR 0.16 MILE TO A STONE HOUSE, AT THE END OF POOR, NARROW,
 LX3817'DIRT ROAD.  STONE HOUSE BURNED DOWN PRIOR TO 1960 WHEN I FIRST
 LX3817'SEARCHED FOR IT, BUT HAS BEEN REBUILT ON OLD FOUNDATION SINCE THAT
 LX3817'YEAR.  FIRST STORY IS OF STONE.  2ND STORY, WOOD, PAINTED RED.
 LX3817'CHIMNEY, N SIDE OF HOUSE, IS MADE OF CONCRETE BLOCKS.  NO SIGNS OF
 LX3817'OCCUPANTS, 4/2/64 NOR 10/22/64.
 LX3817'
 LX3817'155 FT. W OF CHIMNEY OF STONE HOUSE IS A PASSABLE BRIDGE (NO SIDE
 LX3817'RAILINGS) OVER A NARROW BROOK.  CROSS BRIDGE AND GO E, PASSING N OF
 LX3817'STONE HOUSE.  335 FT. E, UP A STEEP GRADE, FROM THE STONE HOUSE
 LX3817'CHIMNEY, IS A BREAK OR OPENING IN THE STONE WALL WHICH LINES THE S
 LX3817'SIDE OF THIS VERY NARROW, ROCKY, DIRT ROAD.  (THIS ROAD HAS RECENTLY
 LX3817'BEEN BULLDOZED ELY, BUT BECAUSE OF ROCKS AND LEDGE IS IMPASSABLE FOR
 LX3817'AN ORDINARY CAR).  AT THE ABOVE NOTED STONEWALL OPENING, TURN SHARP
 LX3817'RIGHT AND GO S ABOUT 40 FT., AND CROSS A NARROW BROOK.  CONTINUE S ON
 LX3817'A PASSABLE TRAIL WHICH GRADUALLY TURNS SELY AND BECOMES NARROWER AND
 LX3817'DIMMER, WINDING CONSIDERABLY, WITH FREQUENT DIM SIDE TRAILS.  ALL IN
 LX3817'THICK FOREST FROM THE BROOK TO THE TOP.
 LX3817'
 LX3817'FROM THE STONE HOUSE TO THE STATION, THE COURSE IS N 120 DEG E,
 LX3817'MAGNETIC, AND I ESTIMATE THE DISTANCE TO BE 0.5 STATUTE MILE.  I
 LX3817'SIMPLY HAD TO USE DEAD RECKONING TO FOLLOW THE COURSE, ALLOWING FOR
 LX3817'TRAIL TACKS TO THE RIGHT AND LEFT.
 LX3817'
 LX3817'ABOUT 0.35 MILE FROM THE WALL OPENING IS AN IMPORTANT FORKS.  TAKE THE
 LX3817'RIGHT HAND ONE AND GO ANOTHER 0.15 MILE ON APPROX. N 120 E, AT WHICH
 LX3817'POINT ONE OF THE THREE CONCRETE FOUNDATIONS CAN BE SEEN ELY ACROSS A
 LX3817'RAVINE, AND THEN UP AN ALMOST SHEER ROCK CLIFF.  (I CLIMBED THIS-ITS
 LX3817'RUGGED-DONT DO IT).  FROM THE ABOVE NOTED POINT* CONTINUE N 120 DEG E,
 LX3817'AND ROUND THE S FACE OF THE ROCK CLIFF, GRADUALLY GOING ELY AND NLY TO
 LX3817'THE SE SIDE OF THE ROCKY OUTCROP, WHERE THE CLIMB TO THE STATION IS
 LX3817'MUCH EASIER.  ALL THIS DETAIL IS NEEDED FOR A STRANGER.  I COULD DO IT
 LX3817'AGAIN WITH NO DIRECTIONS.  BUT I FAILED ON 3 CLIMBS BEFORE 10/22/64.

 LX3817'RECOVERED IN GOOD CONDITION.  A DIFFERENCE OF THE MARK TO MARK SLOPE
 LX3817'MEASUREMENT TO REFERENCE MARKS NO. 1 AND NO. 3 WAS NOTED AND CHECKED
 LX3817'IN THE FIELD.  A NEW AND COMPLETE DESCRIPTION FOLLOWS.
 LX3817'
 LX3817'THE STATION IS LOCATED ON THE SUMMIT OF WOOSTER MOUNTAIN, ABOUT 3-1/2
 LX3817'MILES SOUTHWEST OF DANBURY, 2 MILES SOUTHEAST OF RIDGEBURY VILLAGE,
 LX3817'1-1/2 MILES SOUTH OF THE DANBURY AIRPORT AND ON THE PROPERTY OF MR.
 LX3817'O.F. LIPPOLT.
 LX3817'
 LX3817'TO REACH THE STATION FROM THE JUNCTION OF U.S. HIGHWAY 7 WITH STATE
 LX3817'HIGHWAY 35 WHICH IS ABOUT 6 MILES SOUTH OF DANBURY, GO NORTH ON U.S.
 LX3817'HIGHWAY 7 FOR 3.5 MILES TO A CROSSROAD AND A TRAFFIC LIGHT.  (CHEVRON
 LX3817'SERVICE STATION IN THE NORTHWEST ANGLE OF THE INTERSECTION) TURN LEFT
 LX3817'AND GO IN A WESTERLY DIRECTION ON MIRY BROOK ROAD FOR 0.25 MILE TO A
 LX3817'FORK.  KEEP RIGHT AND CONTINUE WEST ON MIRY BROOK ROAD FOR 0.9 MILE TO
 LX3817'A CROSSROAD WITH A SMALL TRAFFIC TRIANGLE.  KEEP LEFT AND GO SOUTHWEST
 LX3817'ON BACKUS AVENUE FOR 0.55 MILE TO A SIDE ROAD LEFT.  (JUST AFTER
 LX3817'CROSSING A SMALL BRIDGE) TURN LEFT AND GO SOUTH ON PINE MOUNTAIN ROAD
 LX3817'FOR 0.7 MILE TO A SIDE ROAD LEFT AND FOUR MAIL BOXES AND POWER LINE

 LX3817'THE STATION MARK IS A COPPER BOLT WITH CROSS CUT IN THE TOP SET IN A
 LX3817'DRILLED HOLE ABOUT 2 FEET BELOW THE HIGHEST POINT OF A PROMINENT
 LX3817'OUTCROP WHICH ITSELF FORMS THE EXACT SUMMIT OF THE HILL.  THE BOLT HAS
 LX3817'BEEN GIVEN PROTECTION BY CONCRETE WHICH SURROUNDS IT LEAVING A SPACE
 LX3817'SO THAT IT IS STILL VISIBLE.  THIS CONCRETE PROJECTS ABOUT 3 INCHES
 LX3817'ABOVE THE TOP OF THE BOLT.  IT IS 25 FEET SOUTH-SOUTHWEST OF A 24-INCH
 LX3817'TRIANGULAR BLAZED TREE, 9.1 FEET SOUTH-SOUTHEAST OF THE SOUTH EDGE OF
 LX3817'A CONCRETE FOOTING, 8.9 FEET WEST OF THE WEST EDGE OF A CONCRETE

 LX2642.The horizontal coordinates were established by GPS observations
 LX2642.and adjusted by the National Geodetic Survey in June 2012.
 LX2642
 LX2642.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 LX2642.been affixed to the stable North American tectonic plate. See 
 LX2642.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 LX2642
 LX2642.The horizontal coordinates are valid at the epoch date displayed above
 LX2642.which is a decimal equivalence of Year/Month/Day.
 LX2642
 LX2642.The orthometric height was determined by differential leveling and
 LX2642.adjusted by the NATIONAL GEODETIC SURVEY
 LX2642.in June 1991.
 LX2642
 LX2642.Significant digits in the geoid height do not necessarily reflect accuracy.

 LX2642
 LX2642.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 LX2642
 LX2642.The Laplace correction was computed from DEFLEC18 derived deflections.
 LX2642
 LX2642.The ellipsoidal height was determined by GPS observations
 LX2642.and is referenced to NAD 83.
 LX2642
 LX2642.The dynamic height is computed by dividing the NAVD 88
 LX2642.geopotential number by the normal gravity value computed on the
 LX2642.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 LX2642.degrees latitude (g = 980.6199 gals.).
 LX2642
 LX2642.The modeled gravity was interpolated from observed gravity values.

 LX2643.The horizontal coordinates were established by GPS observations
 LX2643.and adjusted by the National Geodetic Survey in June 2012.
 LX2643
 LX2643.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 LX2643.been affixed to the stable North American tectonic plate. See 
 LX2643.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 LX2643
 LX2643.The horizontal coordinates are valid at the epoch date displayed above
 LX2643.which is a decimal equivalence of Year/Month/Day.
 LX2643
 LX2643.The orthometric height was determined by differential leveling and
 LX2643.adjusted by the NATIONAL GEODETIC SURVEY
 LX2643.in June 1991.

 LX2643.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 LX2643
 LX2643.The Laplace correction was computed from DEFLEC18 derived deflections.
 LX2643
 LX2643.The ellipsoidal height was determined by GPS observations
 LX2643.and is referenced to NAD 83.
 LX2643
 LX2643.The dynamic height is computed by dividing the NAVD 88
 LX2643.geopotential number by the normal gravity value computed on the
 LX2643.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 LX2643.degrees latitude (g = 980.6199 gals.).

 LW0725.The horizontal coordinates were established by autonomous hand held GPS
 LW0725.observations and have an estimated accuracy of +/- 10 meters.
 LW0725
 LW0725.The orthometric height was determined by differential leveling and
 LW0725.adjusted by the NATIONAL GEODETIC SURVEY
 LW0725.in June 1991.

 LW0725.The dynamic height is computed by dividing the NAVD 88
 LW0725.geopotential number by the normal gravity value computed on the
 LW0725.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 LW0725.degrees latitude (g = 980.6199 gals.).
