 AA9293.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 AA9293.been affixed to the stable North American tectonic plate. See 
 AA9293.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 AA9293
 AA9293.The horizontal coordinates are valid at the epoch date displayed above
 AA9293.which is a decimal equivalence of Year/Month/Day.
 AA9293
 AA9293.The orthometric height was determined by GPS observations and a
 AA9293.high-resolution geoid model.
 AA9293
 AA9293.GPS derived orthometric heights for airport stations designated as
 AA9293.PACS or SACS are published to 2 decimal places.  This maintains
 AA9293.centimeter relative accuracy between the PACS and SACS.  It does
 AA9293.not indicate centimeter accuracy relative to other marks which are
 AA9293.part of the published vertical control network.

 HW1336'RECOVERY NOTE BY GEOCACHING 2005 (LWB)
 HW1336'DESCRIPTION AND COORDINATES ARE WHERE COBBLESTONE LANE CROSSES THE
 HW1336'NORFOLK AND WESTERN RAILWAY LINE.  NO HOUSES ARE VISABLE FROM THAT
 HW1336'LOCATION.  TALKED TO THREE LOCALS, NONE OF WHICH COULD MAKE SENSE OF
 HW1336'THE DESCRIPTION.  TWO KNEW THE LUCAS NAME, BUT NONE LESTER LUCAS.
 HW1336'TWO REPORTED THE LUCAS FARMHOUSE HAD BURNED, AND THE LOCATION HAD BEEN
 HW1336'BULLDOZED FOR A NEW DRIVEWAY.  REPORTED LOCATION WAS ABOUT 0.2 MILES
 HW1336'FROM THE INTERSECTION OF COBBLESTONE AND THE RAILROAD.

 GA3629.This mark is at Virginia Highland Airport (VJI)
 GA3629
 GA3629.The horizontal coordinates were established by GPS observations
 GA3629.and adjusted by the National Geodetic Survey in June 2012.
 GA3629
 GA3629.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 GA3629.been affixed to the stable North American tectonic plate. See 
 GA3629.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 GA3629
 GA3629.The horizontal coordinates are valid at the epoch date displayed above
 GA3629.which is a decimal equivalence of Year/Month/Day.
 GA3629
 GA3629.The orthometric height was determined by GPS observations and a
 GA3629.high-resolution geoid model.
 GA3629
 GA3629.GPS derived orthometric heights for airport stations designated as
 GA3629.PACS or SACS are published to 2 decimal places.  This maintains
 GA3629.centimeter relative accuracy between the PACS and SACS.  It does
 GA3629.not indicate centimeter accuracy relative to other marks which are
 GA3629.part of the published vertical control network.
 GA3629
 GA3629.Significant digits in the geoid height do not necessarily reflect accuracy.
 GA3629.GEOID18 height accuracy estimate available here.

 GA3629
 GA3629.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 GA3629
 GA3629.The Laplace correction was computed from DEFLEC18 derived deflections.
 GA3629
 GA3629.The ellipsoidal height was determined by GPS observations
 GA3629.and is referenced to NAD 83.

 GV5076'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1943 (RLS)
 GV5076'DISCREPANCIES--THE 1919 DESCRIPTION IS INADEQUATE.  THE
 GV5076'STATION RECOVERED WAS A SECTION OF 1-INCH GALVANIZED PIPE
 GV5076'AND NOT A 4 BY 4 SCANTLING AS MENTIONED IN THE ORIGINAL
 GV5076'DESCRIPTION.  THEREFORE, IT MIGHT BE DOUBTFUL THAT THE FOLLOWING
 GV5076'DESCRIPTION CAN BE APPLIED TO THE STATION ACCACEEK.  HOWEVER,
 GV5076'THERE IS ONLY ONE SUCH POINT ON THE END OF THE MARSH, AS
 GV5076'HAS BEEN DESCRIBED IN 1919.  BECAUSE OF THE AGREEMENT IN
 GV5076'THE LOCATION OF THE GALVANIZED PIPE TO THE LOCATION AS SET
 GV5076'FORTH IN THE ORIGINAL DESCRIPTION, IT SEEMS REASONABLE TO
 GV5076'ASSUME THAT THE STATION RECOVERED IS THE STATION PREVIOUSLY
 GV5076'DESCRIBED.
 GV5076'
 GV5076'NEW DESCRIPTION--THIS STATION IS LOCATED 9 MILES S OF WARSAW,
 GV5076'ON THE POINT OF LAND CALLED ACCACEEK POINT ON THE E SHORE
 GV5076'OF THE RAPPAHANNOCK RIVER.  IT IS ON THE EXTREME POINT OF
 GV5076'LAND BEING ONLY TEN FEET FROM THE WATERS EDGE.  IT IS ABOUT
 GV5076'40 FEET S OF A SMALL INDENTATION IN THE SHORELINE AND ABOUT
 GV5076'235 FEET NW OF A RATHER SHARP INDENTATION IN THE SHORELINE.
 GV5076'IT IS ON MARSHY GROUND ABOUT 800 FEET W OF HARD GROUND.  THE

 GV4609
 GV4609'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1938 (HEF)
 GV4609'THIS IS A COMPLETE DESCRIPTION FOR THIS STATION, USING ALL
 GV4609'PERTINENT FACTS OF THE OLD DESCRIPTIONS AND RECOVERY NOTES.
 GV4609'
 GV4609'THE STATION IS ON THE NORTH SHORE OF THE JAMES RIVER ABOUT
 GV4609'4,000 FEET SOUTHWEST BY SOUTH OF THE MOUTH OF COLLEGE CREEK,
 GV4609'ON A HIGH CLAY BLUFF.  THE HIGH BLUFF ON WHICH THE STATION IS
 GV4609'LOCATED IS BROKEN BY A STRIP OF MARSH, WHICH RUNS INTO THE
 GV4609'BLUFF ABOUT 500 FEET WEST OF THE STATION.  THE STATION IS ON THE
 GV4609'SUMMIT OF OLD CONFEDERATE EARTHWORK FORTIFICATIONS.  IN FORMER
 GV4609'YEARS THESE EARTHWORKS SAT BACK A CONSIDERABLE DISTANCE FROM
 GV4609'THE EDGE OF THE BLUFF, BUT THE BLUFF, WHICH IS ABOUT 25 FEET
 GV4609'HIGH, HAS ERODED BACK TO THE OLD EARTHWORKS, AND THE STATION
 GV4609'IS NOW ONLY 7 FEET FROM THE EDGE OF THE BLUFF.  THE GROUND
 GV4609'IMMEDIATELY INSHORE FROM THE STATION IS LOWER THAN THE
 GV4609'EARTHWORKS ON WHICH THE STATION IS LOCATED, IT BEING THE INNER
 GV4609'PART OF THE FORTIFICATIONS.  THE EARTHEN WALL ON WHICH THE
 GV4609'STATION IS LOCATED EXTENDS ALONG THE EDGE OF THE BLUFF FOR A
 GV4609'HUNDRED METERS OR MORE.  THE STATION IS MARKED BY A NAIL IN THE
 GV4609'CENTER OF A TRIANGLE IMPRESSED IN THE TOP OF A CONCRETE
 GV4609'POST.  1909 AND CGS ARE ALSO IMPRESSED IN THE SURFACE.
 GV4609'THIS POST PROJECTS ABOUT 4 INCHES ABOVE A MASS OF
 GV4609'CONCRETE 20 INCHES IN DIAMETER IN WHICH THE POST IS SET.
 GV4609'FROM THE STATION THE OBSERVATION TOWER NEAR STATION
 GV4609'CRAWFORD SHOWS ABOUT 1/2 DEG LEFT OF THE EAST TANGENT OF
 GV4609'HOG ISLAND AND ABOUT 1 DEG RIGHT OF DEEP WATER SHOALS
 GV4609'LIGHTHOUSE.
 GV4609'
 GV4609'THE REFERENCE MARKS ARE STANDARD COAST AND GEODETIC SURVEY
 GV4609'DISKS IN CONCRETE POSTS.  THEY ARE SET TO THE NORTHWARD FROM
 GV4609'THE STATION, INSIDE THE OLD EARTHWORK FORTIFICATION AND
 GV4609'ABOUT 5 FEET BELOW THE STATION MARK.  THE DISTANCE BETWEEN THE
 GV4609'REFERENCE MARKS IS 14.350 METERS.  THEY ARE PROJECTING ABOVE
 GV4609'THE GROUND ABOUT 3 INCHES.
 GV4609'
 GV4609'THIS STATION IS USED AT FREQUENT INTERVALS BY THE UNITED
 GV4609'STATES ENGINEERS AND THEY KEEP THE IMMEDIATE VICINITY OF THE
 GV4609'STATION CLEARED OF SMALL BRUSH.  TREES AND BUSHES OVERHANG THE
 GV4609'ERODING BLUFF.

 GV4609'THIS STATION IS LOST.  BOTH REFERENCE MARKS WERE RECOVERED IN
 GV4609'GOOD CONDITION.  THE U.S. ENGINEERS HAVE ESTABLISHED A NEW
 GV4609'STATION IN THIS VICINITY, STAMPED ECC A-SHARPE (U.S.E. 1944).
 GV4609'IT IS A SMALL SQUARE CONCRETE BLOCK ABOUT 4 INCHES IN DIAMETER
 GV4609'AND PROJECTING ABOUT 8 INCHES ABOVE THE GROUND.  THE GEOGRAPHIC
 GV4609'POSITION OF THIS NEW STATION IS NOT KNOWN.
 GV4609'
 GV4609'SIGNAL TWIN WAS ESTABLISHED IN THIS VICINITY AND LOCATED BY

 HV3124
 HV3124.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 HV3124.been affixed to the stable North American tectonic plate. See 
 HV3124.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 HV3124
 HV3124.The horizontal coordinates are valid at the epoch date displayed above
 HV3124.which is a decimal equivalence of Year/Month/Day.

 FW1187'THIS STATION WAS INSPECTED AND OLD STATION MARKS SEARCHED FOR
 FW1187'BY ASST. FORNEY, MARCH 14, 1910, BUT NOTHING COULD BE FOUND.
 FW1187'A NEW SITE WAS SELECTED ABOUT WHERE FARLEYS STATION WAS
 FW1187'SUPPOSED TO BE, ON A POINT ABOUT 1/2 MILE TO THE NORTHWARD
 FW1187'OF A CLUBHOUSE, ON THE BRUSH FARM, ON THE NORTHERN END OF
 FW1187'UPSHERS NECK AND ABOUT 2 MILES TO THE SOUTHWARD OF QUINBY AND
 FW1187'ON THE S SIDE OF THE CREEK THAT DIVIDES BRADFORDS AND UPSHERS
 FW1187'NECKS.  IT IS ABOUT 100 METERS S OF THE MOUTH OF THIS CREEK,
 FW1187'ON THE MAINLAND JUST 8 METERS FROM HIGH-WATER MARK ON A
 FW1187'NARROW SAND RIDGE WITH MARSH ON THE W SIDE AND MUD FLATS ON
 FW1187'THE EASTERN SIDE.  THIS STATION CAN ONLY BE APPROACHED
 FW1187'IN A SKIFF AT HALF-HIGH TIDE.  MIDDLE RUN HAS ABOUT 5 FEET
 FW1187'AT LOW WATER.
 FW1187'
 FW1187'YOU CAN ANCHOR ABOUT 1-1/2 MILES FROM THE STATION, GO TO IT
 FW1187'IN A SMALL BOAT AND GET BACK TO THE LAUNCH ON THE NEXT HALF
 FW1187'HIGH-WATER TIDE.  THIS HAS TO BE DONE WHEN YOU HAVE SEVERAL
 FW1187'HOURS WORK AT THE STATION.  IT CAN ALSO BE REACHED FROM
 FW1187'WACHAPREAGUE BY DRIVING 10 MILES.  THIS IS BY FAR THE BEST
 FW1187'WAY TO GET TO THE STATION WHEN OBSERVATIONS ARE TO BE MADE.
 FW1187'
 FW1187'ASST. FORNEY ERECTED AN OBSERVING TRIPOD, 17 FEET HIGH, AND
 FW1187'A SCAFFOLD AROUND IT FROM WHICH TO OBSERVE.  THIS WAS DONE
 FW1187'IN ORDER TO SEE FOWLING 2 AND HAULOVER 2.
 FW1187'

 GV0472.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 GV0472.been affixed to the stable North American tectonic plate. See 
 GV0472.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 GV0472
 GV0472.The horizontal coordinates are valid at the epoch date displayed above
 GV0472.which is a decimal equivalence of Year/Month/Day.

 HV9589.The horizontal coordinates were established by GPS observations
 HV9589.and adjusted by the National Geodetic Survey in June 2012.
 HV9589
 HV9589.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 HV9589.been affixed to the stable North American tectonic plate. See 
 HV9589.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 HV9589
 HV9589.The horizontal coordinates are valid at the epoch date displayed above
 HV9589.which is a decimal equivalence of Year/Month/Day.
 HV9589
 HV9589.The orthometric height was determined by differential leveling and
 HV9589.adjusted by the NATIONAL GEODETIC SURVEY
 HV9589.in September 2004.
 HV9589
 HV9589.Significant digits in the geoid height do not necessarily reflect accuracy.

 HV9589
 HV9589.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 HV9589
 HV9589.The Laplace correction was computed from DEFLEC18 derived deflections.
 HV9589
 HV9589.The ellipsoidal height was determined by GPS observations
 HV9589.and is referenced to NAD 83.
 HV9589
 HV9589.The dynamic height is computed by dividing the NAVD 88
 HV9589.geopotential number by the normal gravity value computed on the
 HV9589.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 HV9589.degrees latitude (g = 980.6199 gals.).
 HV9589
 HV9589.The modeled gravity was interpolated from observed gravity values.

 GV4610'DESCRIBED BY COAST AND GEODETIC SURVEY 1938 (HEF)
 GV4610'THIS STATION IS ON THE NORTH SHORE OF THE JAMES RIVER,
 GV4610'NORTH-NORTHEAST OF HOG POINT, ABOUT 1 MILE EAST OF THE MOUTH OF
 GV4610'COLLEGE CREEK, AND ABOUT 100 METERS EAST OF THE FIRST PROMINENT
 GV4610'RAVINE EAST OF COLLEGE CREEK.  A STEEP-TO BLUFF DIVIDES THE
 GV4610'PROMINENT RAVINE FROM A VALLEY TO THE EASTWARD, UP WHICH AN
 GV4610'ABANDONED ROAD, ALMOST OBLITERATED BY VINES, LEADS AWAY FROM
 GV4610'THE REMAINS OF TWO OLD ABANDONED WHARFS.  THE STATION IS AT
 GV4610'THE FOOT OF THE EASTERN SLOPE OF THE ABOVE-MENTIONED BLUFF
 GV4610'AND ABOUT MIDWAY BETWEEN THE EXTENSIONS OF THE LINES OF THE
 GV4610'PILING OF THE WHARVES.  THE MARK IS 6-1/2 METERS FROM HIGH
 GV4610'WATER LINE, 3.4 METERS SOUTH OF AN OLD SHACK, ABOUT 30
 GV4610'METERS WEST OF A SMALL SLOUGH.  THE STATION IS MARKED BY A
 GV4610'STANDARD MARK SET IN THE SURFACE OF A CONCRETE POST WHICH
 GV4610'WAS POURED TO A DEPTH OF 33 INCHES AROUND A 3- BY 3-INCH PINE
 GV4610'POST DRIVEN 6 FEET INTO THE GROUND.  THE MONUMENT PROJECTS
 GV4610'3 INCHES ABOVE THE SURFACE OF THE GROUND.

 GV4486
 GV4486'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1947 (RRM)
 GV4486'THIS STATION WAS SEARCHED FOR BUT NOT FOUND.  SINCE THE STATION
 GV4486'WAS ESTABLISHED IN 1932, A ROAD WAS BUILT PRACTICALLY ON TOP OF
 GV4486'THE MARK AND THE MARK WAS EITHER DESTROYED OR COVERED WITH
 GV4486'ABOUT 5 FEET OF EARTH.  A NEW STATION BIGLER 4 WAS ESTABLISHED
 GV4486'IN APPROXIMATELY THE SAME POSITION.
 GV4486'
 GV4486'REFERENCE MARK 1, THE PINE TREE, IS GONE.  IT WAS PROBABLY CUT
 GV4486'DOWN WHEN THE ROAD WAS ESTABLISHED.
 GV4486'
 GV4486'REFERENCE MARK 2, THE CEMENT POST, WAS SEARCHED FOR BUT NOT
 GV4486'FOUND.  IT IS BELIEVED TO BE GONE.
 GV4486'
 GV4486'REFERENCE MARK 3, NAIL IN TRIANGLE BLAZE ON CEDAR TREE, WAS FOUND.
 GV4486'THE TRIANGLE BLAZE COULD NOT BE IDENTIFIED FOR CERTAIN BUT
 GV4486'IS BELIEVED TO BE THE TREE REFERRED TO IN THE DESCRIPTION OF
 GV4486'BIGLER 2 AND BIGLER 3.  THE OLD BLAZE FOUND ON THIS TREE WAS
 GV4486'USED AS A WITNESS MARK FOR THE NEW STATION BIGLER 4.

 HV6532'DESCRIBED BY COAST AND GEODETIC SURVEY 1929 (EBL)
 HV6532'THE MARK WAS PLACED ON THE NORTHERNMOST POINT OF HOG ISLAND,
 HV6532'ON THE HIGHEST GROUND IN THE VICINITY, WHICH IS JUST BACK
 HV6532'OF SEVERAL, SMALL SALT BUSHES, ABOUT 20 YARDS FROM THE END
 HV6532'OF THE POINT.  MARK IS THE STANDARD MARK OF THE VIRGINIA-MARYLAND
 HV6532'BOUNDARY COMMISSION (SEE DESCRIPTION OF BOUNDARY MARK NO. 1
 HV6532'FOR THE STANDARD MARK).  THERE IS NO REFERENCE MARK.  THE
 HV6532'PROXIMITY OF STATION HOG MINIMIZES ITS VALUE AS A TRIANGULATION
 HV6532'STATION.

 HV6532
 HV6532'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1942 (TMP)
 HV6532'RECOVERED.  THE SHORE HAS BUILT UP SINCE 1941 AT THIS PLACE,
 HV6532'SO THAT THE MARK IS NOT IN AS MUCH DANGER AS A YEAR AGO
 HV6532'OF BEING WASHED OUT.  THE SHORELINE IS SUBJECT TO FREQUENT
 HV6532'LARGE CHANGES.  AT THE PRESENT TIME HOG ISLAND IS CONNECTED
 HV6532'BY A SAND BEACH AND MARSH LAND TO THE MAINLAND.  THE STATION
 HV6532'WAS REACHED BY DRIVING TO STATION NAVY, 1941 AND WALKING
 HV6532'ALONG THE BEACH DOWNSTREAM TO THE EXTREME NE POINT OF THE
 HV6532'FORMER HOG ISLAND.

 HV6532'THE STATION WAS RECOVERED.  IT WAS FOUND TO BE IN POOR CONDITION.
 HV6532'THE ORIGINAL DESCRIPTION IS ADEQUATE, EXCEPT THAT THE POINT
 HV6532'IS WASHING BADLY, LEAVING THE ENTIRE CONCRETE POST AND ABOUT
 HV6532'1 FOOT OF THE BARREL BASE ABOVE THE SAND.  THE STATION WILL
 HV6532'PROBABLY WASH AWAY DURING THE WINTER MONTHS, AS THIS POINT
 HV6532'IS UNPROTECTED FROM STORMY WEATHER.

 HV6878
 HV6878'DESCRIBED BY MARYLAND-VIRGINIA BOUNDARY COMMISSION 1929 (EBL)
 HV6878'THE MARK WAS PLACED ON THICKET POINT, THE POINT THAT MAKES OUT
 HV6878'INSIDE THE YEOCOMICO AND WHICH IS ABOUT 150 YARDS W OF THE
 HV6878'PRINCIPAL PART OF THE POINT.  IT IS IN A SMALL CLUMP OF CEDARS, TO
 HV6878'THE WESTWARD OF THE MARSHY GROUND THAT EXTENDS WESTWARD FROM THE
 HV6878'TREES THAT GROW ON THE END OF THE POINT. IT IS ABOUT 12 YARDS
 HV6878'INSIDE THE HIGH-WATER LINE AND ABOUT 4 FEET ABOVE THE HIGH-WATER MARK.
 HV6878'
 HV6878'MARK IS THE STANDARD MARK OF THE VIRGINIA-MARYLAND BOUNDARY
 HV6878'COMMISSION (SEE DESCRIPTION OF BOUNDARY MARK NO. 1 FOR THE
 HV6878'STANDARD MARK).  THERE IS NO REFERENCE MARK.  THE POINT IS OF NO
 HV6878'VALUE AS A TRIANGULATION STATION.
 HV6878'
 HV6878'HEIGHT OF SIGNAL ABOVE STATION MARK - 20 METERS.

 GV3818
 GV3818'DESCRIBED BY MARYLAND-VIRGINIA BOUNDARY COMMISSION 1929 (EBL)
 GV3818'THE STATION IS LOCATED ON THE S SHORE OF THE POTOMAC RIVER,
 GV3818'APPROXIMATELY 3/8 MILE DOWNSTREAM FROM PRESLEY CREEK, ON GROUND
 GV3818'ABOUT 4 FEET HIGH, AND ON PROPERTY BELONGING TO MRS. HORNER.
 GV3818'THE MARK IS IN THE BARNYARD, AND THERE IS A LARGE, OLD CHERRY
 GV3818'TREE ABOUT 15 YARDS NORTHWESTERLY OF THE STATION.
 GV3818'
 GV3818'THE MARK IS 30 YARDS FROM THE EDGE OF A BANK ABOUT 4 FEET
 GV3818'HIGH AND THERE HAVE BEEN DRIVEN INTO THE BEACH AT A POINT
 GV3818'JUST OFFSHORE FROM THE MARK, A NUMBER OF SMALL PILES, OR
 GV3818'TRAP STAKES, WHICH WILL AID IN THE RECOVERY OF THE STATION.
 GV3818'THIS POINT IS NOT WELL LOCATED AS A TRIANGULATION STATION,
 GV3818'AS IT WILL NOT SEE POINTS ON THE VIRGINIA SIDE OF THE RIVER,
 GV3818'BUT MAY BE OF VALUE AS TOPOGRAPHIC OR HYDROGRAPHIC CONTROL.
 GV3818'THE MARK IS THE STANDARD MARK OF THE VIRGINIA-MARYLAND
 GV3818'BOUNDARY COMMISSION (SEE DESCRIPTION OF BOUNDARY MARK NO. 1
 GV3818'FOR THE STANDARD MARK).
 GV3818'
 GV3818'THERE IS NO REFERENCE MARK.

 FW0943'STATION BUTLER WAS TAKEN TO BE A LARGE WHITE PINE SCANTLING STAKE,
 FW0943'STANDING 10 FEET BACK FROM TOP ANGLE OF BANK 45 TO 50 FEET
 FW0943'HIGH AND IN ALL RESPECTS VERY MUCH LIKE THE INDEFINITE DESCRIPTION
 FW0943'FURNISHED.  TWO OF THE OLD CEDAR BEARING MARKS WERE FOUND.  THE
 FW0943'UPRIVER ONE, ABOUT 10 INCHES DIAMETER (NOW DEAD) SHOWING THE OLD
 FW0943'BLAZE AND MARK, SECOND MARK ON THE SMALL 7-INCH BRANCH, OF
 FW0943'DOUBLE CEDAR (NOW DEAD) BUT SHOWING MARK AND NAILS WELL, ALSO
 FW0943'FOUND A 4-INCH TILE SET BACK IN WOODS IN SAND AND NOT FILLED
 FW0943'WITH ANYTHING, NOW FILLED WITH AND SUPPORTED IN BED OF
 FW0943'CEMENT.  THE DISTANCES GIVEN DO NOT AGREE AND ARE ONLY TO
 FW0943'EVEN FEET AND MANY HAVE BEEN GUESSED.
 FW0943'
 FW0943'REFERENCE MARK NO. 1 IS OLD BLAZE ON 10-INCH CEDAR 4-1/2 FEET

 FW0943
 FW0943'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1934 (JCT)
 FW0943'NO TRACE OF STATION OR REFERENCE MARKS COULD BE FOUND.  THE BLUFF
 FW0943'IN THIS VICINITY SHOWS SIGNS OF EROSION AND IT IS PROBABLE THAT
 FW0943'THE MARKS HAVE BEEN DESTROYED IN YEARS PAST.  THE RECOVERY OF THE
 FW0943'EXACT LOCATION OF THE STATION WAS VERY UNCERTAIN DUE TO THE
 FW0943'INDEFINITE DESCRIPTION, BUT SINCE THE MARK WAS ONLY 10 FEET BACK
 FW0943'FROM THE EDGE OF THE HIGH BLUFF, IT HAS ALMOST CERTAINLY BEEN
 FW0943'WASHED OUT.

 HW1220.The horizontal coordinates were established by GPS observations
 HW1220.and adjusted by the National Geodetic Survey in June 2012.
 HW1220
 HW1220.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 HW1220.been affixed to the stable North American tectonic plate. See 
 HW1220.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 HW1220
 HW1220.The horizontal coordinates are valid at the epoch date displayed above
 HW1220.which is a decimal equivalence of Year/Month/Day.
 HW1220
 HW1220.The orthometric height was determined by differential leveling and
 HW1220.adjusted by the NATIONAL GEODETIC SURVEY
 HW1220.in June 1991.
 HW1220
 HW1220.Significant digits in the geoid height do not necessarily reflect accuracy.
 HW1220.GEOID18 height accuracy estimate available here.
 HW1220
 HW1220.Click photographs - Photos may exist for this station.
 HW1220
 HW1220.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 HW1220
 HW1220.The Laplace correction was computed from DEFLEC18 derived deflections.
 HW1220
 HW1220.The ellipsoidal height was determined by GPS observations
 HW1220.and is referenced to NAD 83.
 HW1220
 HW1220.The dynamic height is computed by dividing the NAVD 88
 HW1220.geopotential number by the normal gravity value computed on the
 HW1220.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 HW1220.degrees latitude (g = 980.6199 gals.).
 HW1220
 HW1220.The modeled gravity was interpolated from observed gravity values.
 HW1220
 HW1220. The following values were computed from the NAD 83(2011) position.

 GV4566                          STATION DESCRIPTION
 GV4566
 GV4566'DESCRIBED BY VIRGINIA COMMISSION OF FISHERIES 1938 (HEF)
 GV4566'THIS STATION WAS ESTABLISHED BY THE VIRGINIA COMMISSION OF
 GV4566'FISHERIES ON A PROMINENT BLUFF WEST-NORTHWEST OF PAGAN RIVER
 GV4566'ABOUT 1/2 MILE ABOVE DAYS POINT.  STATION IS ABOUT 335 METERS
 GV4566'EAST BY SOUTH OF A PROMINENT DRAW OR RAVINE INDENTING THE
 GV4566'BLUFF AND LEADING UP PAST AND ON THE WEST SIDE OF THE BUILDINGS
 GV4566'OF UPTONS FARM, THE BARN OF WHICH IS A LARGE GRAY CORRUGATED
 GV4566'METAL BUILDING AND PROMINENT ALONG THE RIVER.
 GV4566'
 GV4566'STATION IS ON THE FENCE LINE AT THE NORTHEAST CORNER
 GV4566'OF AN OPEN FIELD NOW USED AS PASTURE LAND.  THERE ARE NUMEROUS
 GV4566'SCATTERED SMALL CEDAR TREES IN THE FIELD.  THE APPROXIMATE
 GV4566'LOCATION OF THE STATION IS EASILY LOCATED BY A LARGE LONE CEDAR
 GV4566'TREE ON THE EDGE OF THE BLUFF THAT IS PROMINENT FROM THE RIVER.
 GV4566'THIS TREE IS 5.33 METERS FROM THE STATION AND ABOUT ON LINE
 GV4566'BETWEEN THE STATION AND MULBERRY POINT.  THIS TREE PROBABLY
 GV4566'WILL NOT LAST MANY YEARS SINCE IT IS NOW ON THE VERY EDGE OF
 GV4566'THE STEEP-TO CLAY BLUFF.
 GV4566'
 GV4566'THE STATION WAS ORIGINALLY MARKED BY A 2-INCH GALVANIZED IRON
 GV4566'PIPE EXTENDING ABOUT 1 FOOT ABOVE GROUND.  THE STATION WAS
 GV4566'RE-MARKED AS FOLLOWS--PIPE WAS DRIVEN DOWN SO THAT THE PIPE
 GV4566'TOP PROTRUDED ABOUT 3 INCHES ABOVE SURFACE OF GROUND.  A
 GV4566'CONCRETE POST 10 INCHES ON A SIDE WAS POURED AROUND THE PIPE.
 GV4566'THE PIPE WAS FILLED WITH CONCRETE AND A STANDARD COAST AND
 GV4566'GEODETIC SURVEY STATION MARK WAS CEMENTED IN THE CENTER OF THE
 GV4566'TOP OF THE PIPE.  THE MARK IS 3.3 METERS BACK FROM EDGE OF
 GV4566'BLUFF.
 GV4566'
 GV4566'SURFACE AND REFERENCE MARKS ARE STANDARD BRONZE DISKS SET
 GV4566'IN CONCRETE.
 GV4566'
 GV4566'REFERENCE MARK NO. 1 IS IN THE FENCE LINE 17.9 METERS FROM THE
 GV4566'EDGE OF THE BLUFF.
 GV4566'
 GV4566'REFERENCE MARK NO. 2 IS 16.5 METERS FROM THE EDGE OF THE BLUFF,
 GV4566'AND FROM THE REFERENCE MARK THE STATION AND WHITE SHOAL
 GV4566'LIGHTHOUSE ARE ON LINE.
 GV4566'
 GV4566'A 6-FOOT STAND WAS USED HERE TO CLEAR THE BRUSH AND GRASS
 GV4566'ALONG THE BLUFF ON THE LINE TO POINT OF SHOALS.
 GV4566
 GV4566                          STATION RECOVERY (1942)
 GV4566
 GV4566'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1942 (LWS)
 GV4566'1938 DESCRIPTION ADEQUATE.
 GV4566'
 GV4566'NOTE--THE CEDAR MENTIONED IN THE DESCRIPTION IS NOW DEAD AND
 GV4566'ON EDGE OF BLUFF.  NONE OF THE DISKS ARE STAMPED.
 GV4566
 GV4566                          STATION RECOVERY (1947)
 GV4566
 GV4566'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1947 (RRM)
 GV4566'STATION FOUND AS DESCRIBED.  THE LARGE LONE CEDAR HAS FALLEN
 GV4566'OVER THE BLUFF AND DISAPPEARED ENTIRELY.  THE STATION IS NOW
 GV4566'OUTSIDE THE FENCE LINE AND ABOUT 3 FEET FROM THE EDGE OF THE
 GV4566'BLUFF.  AS THE BLUFF IS UNDERCUT ALONG THIS STRETCH IT IS
 GV4566'DOUBTFUL WHETHER THE STATION WILL LAST MUCH LONGER.

 JV6140.This mark is at Leesburg Mun/godfrey Fld Airport (JYO)
 JV6140
 JV6140.The horizontal coordinates were established by GPS observations
 JV6140.and adjusted by the National Geodetic Survey in June 2012.
 JV6140
 JV6140.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 JV6140.been affixed to the stable North American tectonic plate. See 
 JV6140.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 JV6140
 JV6140.The horizontal coordinates are valid at the epoch date displayed above
 JV6140.which is a decimal equivalence of Year/Month/Day.
 JV6140
 JV6140.The orthometric height was determined by GPS observations and a
 JV6140.high-resolution geoid model.
 JV6140
 JV6140.GPS derived orthometric heights for airport stations designated as
 JV6140.PACS or SACS are published to 2 decimal places.  This maintains
 JV6140.centimeter relative accuracy between the PACS and SACS.  It does
 JV6140.not indicate centimeter accuracy relative to other marks which are
 JV6140.part of the published vertical control network.
 JV6140
 JV6140.Significant digits in the geoid height do not necessarily reflect accuracy.

 GV5314'AND RECOVERY NOTES.
 GV5314'
 GV5314'STATION IS ON THE NORTH SHORE OF THE JAMES RIVER, IN THE
 GV5314'SOUTHWEST CORNER OF THE OLD MILTON ESTATE, ON THE FIRST
 GV5314'HIGH GROUND BELOW (NORTHEAST) THE MOUTH OF KITTEWAN CREEK.
 GV5314'IT IS ON TOP OF AND 20 METERS BACK FROM THE EDGE OF A
 GV5314'35-FOOT BLUFF, THAT IS HEAVILY WOODED WITH 60-FOOT TREES,
 GV5314'MOSTLY DECIDUOUS.  THE MARK IS 1.85 METERS FROM THE TALLEST
 GV5314'CEDAR TREE ON THE BLUFF, 14.7 METERS WEST OF A TREE WITH OLD
 GV5314'TRIANGULAR BLAZE AND 16.6 METERS FROM A LARGE OAK WITH
 GV5314'TRIANGULAR BLAZE THAT STANDS AT THE EDGE OF THE BLUFF.  THE MARK
 GV5314'IS 27 METERS FROM THE EDGE OF THE BLUFF AT A POINT
 GV5314'DIRECTLY ABOVE AN 18-INCH DIAMETER OAK TREE THAT IS
 GV5314'GROWING ON THE SLOPE OF THE BLUFF ABOUT MIDWAY BETWEEN
 GV5314'THE WATER AND THE TOP OF THE BLUFF.  DOWNSTREAM FROM
 GV5314'THIS OAK TREE THE BLUFF IS SHEER AND BARE.  UPSTREAM IT
 GV5314'IS SLOPING AND WOODED.  THE UPSTREAM END OF THE BLUFF IS
 GV5314'ABOUT 100 METERS ABOVE THIS TREE, AND A FAINT TRAIL
 GV5314'LEADS UP ITS WESTERLY SLOPE FROM THE REMAINS OF A SMALL
 GV5314'BOAT WHARF IN A TINY BIGHT AT THE POINT OF THE BLUFF.
 GV5314'THE STATION IS MARKED WITH A NAIL CENTERED IN CONCRETE IN A
 GV5314'2-INCH IRON PIPE WHICH IS CENTERED AND CEMENTED IN A 4-INCH
 GV5314'DRAIN TILE, WHICH IN TURN IS SET IN A MASS OF CONCRETE
 GV5314'ABOUT 12 INCHES IN DIAMETER.  THE MARK PROJECTS 4
 GV5314'INCHES.  THERE IS NO SUB-SURFACE MARK.  THE REFERENCE MARKS
 GV5314'ARE STANDARD DISKS IN CONCRETE POST.  A 70-FOOT TOWER WAS
 GV5314'NEEDED TO CLEAR ALL LOCAL TREES.  CLEARING IS NECESSARY TO
 GV5314'SEE BRIAR OR JDA FROM GROUND.  THE BLUFF HERE IS NOT ERODING.

 GV5315
 GV5315'DESCRIBED BY COAST AND GEODETIC SURVEY 1938 (HEF)
 GV5315'STATION IS ON THE NORTHEAST SHORE OF THE JAMES RIVER, EAST
 GV5315'BY NORTH FROM WINDMILL POINT, ABOUT 3/4 MILES DOWNSTREAM
 GV5315'(SOUTH BY EAST) FROM THE MOUTH OF QUEENS CREEK, ON THE MOST
 GV5315'PROMINENT BLUFF IN THE VICINITY, ON A POINT OF THE BLUFF
 GV5315'FORMED BY A DEEP RAVINE RUNNING INTO THE BLUFF TO THE NORTHEAST.
 GV5315'THIS RAVINE CAN BE LOCATED READILY FROM THE RIVER BY THE
 GV5315'COTTAGE AT ITS MOUTH NEAR THE BANK OF THE RIVER AND THE POINT
 GV5315'OF THE BLUFF.  THE STATION IS ON THE NORTH SIDE OF THE RAVINE,
 GV5315'36 FEET INSHORE FROM THE EDGE OF THE RIVER BLUFF, MEASURED
 GV5315'IN THE DIRECTION OF WINDMILL POINT, 44 FEET FROM THE POINT
 GV5315'OF BLUFF AT STAIRWAY LEADING DOWN POINT OF BLUFF TO COTTAGE
 GV5315'AT RIVER, AND 55 FEET FROM A 24-INCH OAK WITH TRIANGULAR
 GV5315'BLAZE ON NORTHWEST EDGE OF RAVINE.  THIS TREE IS THE
 GV5315'LARGEST ONE OF MANY TREES ON THE NORTHWEST SIDE OF THE
 GV5315'RAVINE.  THE STATION IS ON THE PROPERTY OF MR. COPELAND,
 GV5315'ON THE EDGE OF HIS CULTIVATED FIELD AND AT THE END OF A ROAD
 GV5315'LEADING IN FROM THE HIGHWAY TO THE COTTAGE AT THE FOOT OF
 GV5315'THE BLUFF.  THE STATION MARK PROJECTS ABOUT 3 INCHES
 GV5315'ABOVE THE SURFACE OF THE GROUND.
 GV5315'
 GV5315'SURFACE, UNDERGROUND AND REFERENCE MARKS ARE STANDARD BRONZE
 GV5315'DISKS IN CONCRETE, NOTES 1A, 7A AND 11A.
 GV5315'
 GV5315'REFERENCE MARK NO. 1 IS AMONG THE TREES BETWEEN THE ROAD
 GV5315'AND THE HEAD OF THE RAVINE.  REFERENCE MARK NO. 2 IS 5 METERS
 GV5315'EAST OF THE EDGE OF THE RIVER BLUFF BETWEEN THE CULTIVATED
 GV5315'GROUND AND THE FRINGLE OF TREES THAT GROW ALONG THE EDGE OF
 GV5315'THE BLUFF.
 GV5315'
 GV5315'A 100-FOOT TOWER WAS NECESSARY HERE TO SEE THE GROUND AT
 GV5315'STATION DUNN.  A 60-FOOT TOWER IS NECESSARY TO CLEAR THE
 GV5315'LOCAL TREES TO SOUTH AND EAST.  THE FRINGE OF TREES ALONG THE
 GV5315'EDGE OF THE BLUFF COULD BE CLEARED READILY, MAKING WINDMILL
 GV5315'POINT AND THE NORTH SHORE OF THE RIVER IN THE VICINITY OF
 GV5315'WILLCOX WHARF VISIBLE FROM THE GROUND AT THE STATION.

 GV3893
 GV3893'DESCRIBED BY COAST AND GEODETIC SURVEY 1913 (OWF)
 GV3893'STATION COSTIN IS ON A WIDE SANDY BELT, 910 METERS BELOW POINT
 GV3893'ELLIOTT, WHERE HIGH POINT OF SAND RIDGE COMES TO BEACH AND ABOUT
 GV3893'1300 METERS ABOVE LOWER END OF THIS LOW SANDY AND GRASSY BEND,
 GV3893'15 METERS BACK FROM GRASS LINE OF BEACH, AND 100 METERS IN FRONT
 GV3893'OF PINE WOOD LINE AND ON TOP OF A RELATIVELY HIGH KNOLL OF SAND,
 GV3893'ABOUT 7 FEET IN ELEVATION ABOVE MEAN TIDE.  STATION IS MARKED BY
 GV3893'A 8- BY 8- BY 24-INCH CEMENT BLOCK, SET WITH TOP 4 INCHES ABOVE
 GV3893'SURFACE IN A BED OF CEMENT, BEARING THE REGULATION DISK,
 GV3893'REINFORCED IN TOP AND CENTER.  SUBSURFACE MARK IS THE NOZZLE OF A
 GV3893'PINT BEER BOTTLE.
 GV3893'
 GV3893'REFERENCE MARK IS ON VERY SHARP AND PROMINENT GRASSY MOUND 30
 GV3893'METERS IN FRONT OF WOOD LINE, AN 8- BY 8- BY 24-INCH CEMENT BLOCK
 GV3893'BEARING THE BRASS DISK WITH ARROW IN TOP AND CENTER, STANDING
 GV3893'3 INCHES ABOVE SURFACE, DISTANCE 101.491 METERS ON LINE 288 DEG

 GV3893
 GV3893'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1934 (JCT)
 GV3893'THE STATION MARK COULD NOT BE FOUND AFTER A THOROUGH SEARCH IN
 GV3893'THE VICINITY.  THE REFERENCE MARK WAS RECOVERED IN GOOD CONDITION
 GV3893'AND APPARENTLY IN PLACE.  FROM MEASUREMENTS MADE FROM THE REFERENCE
 GV3893'MARK IT WAS ASCERTAINED THAT THE STATION MARK CAME VERY NEAR THE
 GV3893'EDGE OF THE LOW SAND BLUFF ALONG CHESAPEAKE BAY AND HAS EITHER
 GV3893'BEEN WASHED OUT OR COVERED WITH SAND.  THERE IS EVIDENCE THAT THE
 GV3893'SHORE LINE HAS WASHED BADLY IN THIS VICINITY.
 GV3893'
 GV3893'THE FIRST-ORDER TRIANGULATION STATION WILLIS, 1932, IS LOCATED
 GV3893'ABOUT 250 METERS TO N OF THE RECOVERED REFERENCE MARK FOR COSTIN.
 GV3893'IT IS BELIEVED THAT THIS REFERENCE MARK IS ALSO THE REFERENCE
 GV3893'MARK NO. 3 FOR STATION WILLIS, 1932 AS MENTIONED IN THE
 GV3893'DESCRIPTION FOR THAT STATION.

 GW2307'DESCRIBED BY COAST AND GEODETIC SURVEY 1941 (GWL)
 GW2307'THIS IS A TRAVERSE STATION LOCATED BY DISTANCE AND DIRECTION FROM
 GW2307'TRIANGULATION STATION CUMBERLAND.
 GW2307'
 GW2307'THE STATION IS IN THE TOWN OF CUMBERLAND COURTHOUSE.  IT IS 9.5
 GW2307'FEET N OF THE COURTHOUSE SIDEWALK AT THE ENTRANCE TO THE COURTHOUSE
 GW2307'GROUNDS.  IT IS 41 FEET WNW OF THE CENTER OF U.S. HIGHWAY 60.  THE
 GW2307'MARK IS A 5- BY 8-INCH CONCRETE POST THAT PROJECTS ABOUT 8
 GW2307'INCHES ABOVE THE SURFACE OF THE GROUND.  THE LETTERS U.S.C. AND
 GW2307'G.S.S.M. ARE STAMPED IN THE TOP.  A DRILL HOLE IN THE CENTER OF
 GW2307'THE TOP MARKS THE STATION.  IT IS 24.860 METERS (81.56 FEET),
 GW2307'HORIZONTAL DISTANCE, NW OF TRIANGULATION STATION CUMBERLAND.

 GV0205.The horizontal coordinates were established by GPS observations
 GV0205.and adjusted by the National Geodetic Survey in June 2012.
 GV0205
 GV0205.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 GV0205.been affixed to the stable North American tectonic plate. See 
 GV0205.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 GV0205
 GV0205.The horizontal coordinates are valid at the epoch date displayed above
 GV0205.which is a decimal equivalence of Year/Month/Day.
 GV0205
 GV0205.No horizontal observational check was made to the station.
 GV0205
 GV0205.The orthometric height was determined by differential leveling and
 GV0205.adjusted by the NATIONAL GEODETIC SURVEY
 GV0205.in June 1991.
 GV0205
 GV0205.Significant digits in the geoid height do not necessarily reflect accuracy.

 GV0205.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 GV0205
 GV0205.The Laplace correction was computed from DEFLEC18 derived deflections.
 GV0205
 GV0205.The ellipsoidal height was determined by GPS observations
 GV0205.and is referenced to NAD 83.
 GV0205
 GV0205.The dynamic height is computed by dividing the NAVD 88
 GV0205.geopotential number by the normal gravity value computed on the
 GV0205.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 GV0205.degrees latitude (g = 980.6199 gals.).
 GV0205
 GV0205.The modeled gravity was interpolated from observed gravity values.

 GV4638'DESCRIBED BY COAST SURVEY (CGS) 1870 (REH)
 GV4638'THIS STATION IS ON THE SOUTH SIDE OF THE JAMES RIVER A LITTLE
 GV4638'WEST OF OPPOSITE TO JAMESTOWN RUINS, AND IS LOCATED ON SWANS
 GV4638'POINT WHICH IS THE NORTHEAST PORTION OF THE LANDS NOW OWNED
 GV4638'BY A. ALDRIDGE.  IT IS BETWEEN JONES STATION ON THE EAST
 GV4638'AND ALDRIDGE STATION ON THE WEST.
 GV4638'
 GV4638'THE STATION IS MARKED BY A BROKEN GLASS BOTTLE 4-1/2 FEET

 GV4638
 GV4638'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1938 (HEF)
 GV4638'THIS STATION IS ON THE SOUTH SHORE OF THE JAMES RIVER, EAST
 GV4638'OF A SMALL ISLAND OF MADE LAND THAT WAS CREATED BY DREDGING
 GV4638'OPERATIONS, ON THE NORTHERLY AND CENTRAL OF THREE DISTINCT
 GV4638'POINTS THAT FORM A PART OF SWAN POINT.  IT IS 3.9 METERS
 GV4638'OUTSIDE THE HIGH WATER LINE, ON FIRM GROUND THAT IS BARE
 GV4638'AT LOW WATER, 0.6 METER EAST OF WEST EDGE OF GRASS LINE,
 GV4638'1.8 METERS WEST OF EAST GRASS LINE, AND 1.5 METERS SOUTH
 GV4638'OF NORTHERLY TIP ALONG GRASS LINE.  THE STATION IS MARKED
 GV4638'BY A CONCRETE POST THAT IS 6 INCHES SQUARE AT THE TOP.  THE
 GV4638'CENTER IS A NAIL SET IN THE CENTER OF A TRIANGLE THAT IS
 GV4638'IMPRESSED IN THE SURFACE OF THE CONCRETE.  1910 AND CGS
 GV4638'ARE ALSO IMPRESSED IN THE SURFACE OF THE MARK.
 GV4638'
 GV4638'TWO STANDARD REFERENCE MARKS IN CONCRETE POSTS WERE ESTABLISHED
 GV4638'INSHORE FROM THE STATION, ON THE SAND STRIP THAT HAS WASHED
 GV4638'UP AMONG THE CYPRESS TREES ON THE POINT.
 GV4638'
 GV4638'THE WITNESS MARKS ARE ALL NAILS IN THE CENTER OF TRIANGULAR
 GV4638'BLAZES ON TREES.  NO. 1 IS ON THE LARGE DEAD CYPRESS, DIRECTLY
 GV4638'OFFSHORE FROM THE STATION, THE MOST NORTHERLY TREE ON THE
 GV4638'POINT.
 GV4638'
 GV4638'SWAN (U.S.E.), A STATION THAT WAS ESTABLISHED ON THE FIRST
 GV4638'POINT, 259.6 METERS WEST OF THE STATION, AND CONNECTED
 GV4638'TO THE STATION BY TRAVERSE IN 1910, WAS SEARCHED FOR BUT
 GV4638'NOT FOUND.  THE POINT ON WHICH IT WAS LOCATED SHOWS EVIDENCE
 GV4638'OF EXTENSIVE EROSION AND IT IS BELIEVED THAT THIS MARK HAS
 GV4638'BEEN CARRIED AWAY.
 GV4638'
 GV4638'THE ABOVE IS A COMPLETE REVISED DESCRIPTION OF THIS STATION,
 GV4638'USING ALL PERTINENT INFORMATION FROM FORMER DESCRIPTIONS.

 GV4638'BOTH REFERENCE MARKS RECOVERED.  THE REFERENCE MARKS ARE
 GV4638'WELL WITHIN THE BRUSH AND NEAR INNER EDGE OF SANDSPIT BETWEEN
 GV4638'MARSH AND RIVER.  STATION MARK WAS FOUND ON ITS SIDE ABOUT
 GV4638'8 METERS OUTSIDE THE HIGH-WATER LINE.  NO SITE FOR RE-MARKING
 GV4638'THAT OFFERS BETTER PROTECTION FROM EROSION THAN THOSE OCCUPIED
 GV4638'BY REFERENCE MARKS.  BOTH REFERENCE MARKS ARE APPROXIMATELY
 GV4638'6 METERS INSIDE THE HIGH-WATER LINE.  POINT IS NOW A DOUBLE
 GV4638'POINT HAVING TWO PROJECTIONS.  REFERENCE MARKS ARE NEAR
 GV4638'THE W ONE OF THESE POINTS.

 GV4638
 GV4638'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1956 (ELJ)
 GV4638'THE STATION IS LOST.  WITNESS MARKS NO. 3 AND NO. 4 WERE
 GV4638'RECOVERED AS DESCRIBED.  REFERENCE MARK NO. 2 WAS FOUND
 GV4638'BUT THE SAND IN WHICH IT WAS SET HAS WASHED AWAY LEAVING
 GV4638'THE MONUMENT PROJECTING ABOUT 16 INCHES AND IN A LOOSE CONDITION.
 GV4638'REFERENCE MARK NO. 1 WAS COMPLETELY WASHED OUT AND THE MONUMENT
 GV4638'WAS FOUND LYING ON ITS SIDE.  THE MARK WAS DESTROYED.  THE
 GV4638'POSITION OF THE STATION MARK WAS RECONSTRUCTED BY MEASUREMENTS
 GV4638'AND SEXTANT ANGLES FROM THE RECOVERED WITNESS MARKS AND
 GV4638'REFERENCE MARK NO. 2.  A LARGE SOLID OBJECT WHICH IS BELIEVED
 GV4638'TO BE THE STATION MONUMENT LYING ON ITS SIDE WAS FOUND BY
 GV4638'PROBING ABOUT 2 METERS OFFSHORE FROM THE RECONSTRUCTED
 GV4638'LOCATION IN ABOUT 30 INCHES OF WATER.

 AH8544.This mark is at Danville Airport (DAN)
 AH8544
 AH8544.The horizontal coordinates were established by GPS observations
 AH8544.and adjusted by the THE THRASHER GROUP, INC in October 2016.
 AH8544
 AH8544.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 AH8544.been affixed to the stable North American tectonic plate. See 
 AH8544.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 AH8544
 AH8544.The horizontal coordinates are valid at the epoch date displayed above
 AH8544.which is a decimal equivalence of Year/Month/Day.
 AH8544
 AH8544.The orthometric height was determined by GPS observations and a
 AH8544.high-resolution geoid model.
 AH8544
 AH8544.GPS derived orthometric heights for airport stations designated as
 AH8544.PACS or SACS are published to 2 decimal places.  This maintains
 AH8544.centimeter relative accuracy between the PACS and SACS.  It does
 AH8544.not indicate centimeter accuracy relative to other marks which are
 AH8544.part of the published vertical control network.
 AH8544
 AH8544.Significant digits in the geoid height do not necessarily reflect accuracy.
 AH8544.GEOID18 height accuracy estimate available here.

 AH8544
 AH8544.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 AH8544
 AH8544.The Laplace correction was computed from DEFLEC18 derived deflections.
 AH8544
 AH8544.The ellipsoidal height was determined by GPS observations
 AH8544.and is referenced to NAD 83.

 GV4613'THIS STATION IS ON THE WEST BANK OF THE JAMES RIVER, ABOUT 1/2
 GV4613'MILE SOUTH OF THE NORTHEAST TANGENT OF LAWNS POINT, ON TOP
 GV4613'OF AND ABOUT 15 FEET INSHORE FROM THE EDGE OF A 25-FOOT BLUFF,
 GV4613'AND ABOUT 200 METERS SOUTH OF THE PROJECTED LINE OF THE FORT
 GV4613'EUSTIS WHARF ACROSS THE RIVER.  THE BLUFF IS WOODED AND THE
 GV4613'STATION SITE WAS SELECTED SO THAT LINES TO GHOST AND HOG 3
 GV4613'COULD BE CLEARED WITHOUT CUTTING LARGE TREES, AND SO THAT
 GV4613'THE LINE TO EUSTIS, A STATION 90 METERS SOUTH OF THE INNER
 GV4613'END OF FORT EUSTIS WHARF, WOULD BE WELL CLEAR OF A LARGE
 GV4613'VESSEL LAID UP AND MOORED TO THE OUTER END OF THE WHARF.

 GV3632'DESCRIBED BY COAST AND GEODETIC SURVEY 1944 (FLG)
 GV3632'THE STATION IS LOCATED ON DYMERS OR GREAT NECK, ON THE W SIDE
 GV3632'OF FLEETS BAY, BETWEEN INDIAN AND DYMERS CREEKS.  THE STATION IS
 GV3632'ON HARD LAND IN A CUT-OVER AREA AND IS LARGELY GROWN UP IN BRUSH.
 GV3632'
 GV3632'THE STATION IS 16.7 METERS W OF THE HIGH-WATER LINE AT A
 GV3632'POINT ABOUT 300 METERS N OF THE HIGH-WATER LINE AT THE S END OF
 GV3632'THE MAIN SECTION OF THE POINT.
 GV3632'
 GV3632'THE STATION MARK IS A BRONZE TRAVERSE DISK STAMPED DIME 1944
 GV3632'AND SET IN CONCRETE.  IT PROJECTS 4 INCHES.
 GV3632'
 GV3632'TO REACH THE STATION FROM KILMARNOCK, GO SW ALONG ROAD TO
 GV3632'WHITESTONE TO GREAT NECK ROAD, TURN LEFT ALONG GREAT NECK ROAD TO
 GV3632'END OF TAR, THEN TAKE DIRT ROAD STRAIGHT AHEAD.  WHEN DIRT ROAD
 GV3632'TURNS LEFT, CONTINUE STRAIGHT PAST ELEVATED WATER TANK.  CONTINUE
 GV3632'ON THIS ROAD UNTIL ROAD ENDS.  STATION IS ON RIGHT AT END OF
 GV3632'ROAD.  THIS METHOD OF REACHING STATION SHOULD NOT BE ATTEMPTED BY
 GV3632'TRUCK IN WET WEATHER.
 GV3632'
 GV3632'REFERENCE MARK 1 IS LOCATED AT THE EDGE OF THE TRAIL MENTIONED
 GV3632'ABOVE, 32.0 METERS W OF HIGH-WATER LINE, AND 3 METERS E OF

 GV3632'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1952 (DFR)
 GV3632'STATION IS LOST.  REFERENCE MARK 1 WAS FOUND IN GOOD CONDITION.
 GV3632'MEASUREMENTS WERE TAKEN TO THE DESCRIBED LOCATION OF DIME 2,
 GV3632'AND THE POSITION FELL SEVERAL METERS INTO THE WATER.  THE BLUFF
 GV3632'IS ERODING VERY RAPIDLY HERE.  AFTER A HALF-HOUR THE SEARCH FOR
 GV3632'REFERENCE MARK 2 WAS GIVEN UP, HOWEVER, THE UNDERBRUSH IS VERY
 GV3632'DENSE AND THE MARK PROBABLY EXISTS.
 GV3632'
 GV3632'ABANDONMENT OF THE DESCRIBED ACCESS ROAD AND THE DEVELOPMENT
 GV3632'OF A NEW ROAD MAKES THE PREVIOUS ACCESS DESCRIPTION INADEQUATE.
 GV3632'
 GV3632'TO REACH STATION FROM KILMARNOCK, GO SE ALONG HIGHWAY 200 TOWARD
 GV3632'WHITESTONE TO FLEETS BAY NECK ROAD, TURN LEFT AND FOLLOW BEYOND

 AI9596.This is a reference station for the DRIVER 1
 AI9596.National Continuously Operating Reference Station (DRV1).
 AI9596
 AI9596.The horizontal coordinates were established by GPS observations
 AI9596.and adjusted by the National Geodetic Survey in June 2012.
 AI9596
 AI9596.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 AI9596.been affixed to the stable North American tectonic plate. See 
 AI9596.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 AI9596
 AI9596.The horizontal coordinates are valid at the epoch date displayed above
 AI9596.which is a decimal equivalence of Year/Month/Day.
 AI9596
 AI9596.The orthometric height was determined by differential leveling and
 AI9596.adjusted by the NATIONAL GEODETIC SURVEY
 AI9596.in July 2002.
 AI9596
 AI9596.No vertical observational check was made to the station.
 AI9596
 AI9596.Significant digits in the geoid height do not necessarily reflect accuracy.
 AI9596.GEOID18 height accuracy estimate available here.
 AI9596
 AI9596.Click photographs - Photos may exist for this station.
 AI9596
 AI9596.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 AI9596
 AI9596.The Laplace correction was computed from DEFLEC18 derived deflections.
 AI9596
 AI9596.The ellipsoidal height was determined by GPS observations
 AI9596.and is referenced to NAD 83.
 AI9596
 AI9596.The dynamic height is computed by dividing the NAVD 88
 AI9596.geopotential number by the normal gravity value computed on the
 AI9596.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 AI9596.degrees latitude (g = 980.6199 gals.).
 AI9596
 AI9596.The modeled gravity was interpolated from observed gravity values.

 AI9595.This is a reference station for the DRIVER 1
 AI9595.National Continuously Operating Reference Station (DRV1).
 AI9595
 AI9595.The horizontal coordinates were established by GPS observations
 AI9595.and adjusted by the National Geodetic Survey in June 2012.
 AI9595
 AI9595.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 AI9595.been affixed to the stable North American tectonic plate. See 
 AI9595.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 AI9595
 AI9595.The horizontal coordinates are valid at the epoch date displayed above
 AI9595.which is a decimal equivalence of Year/Month/Day.
 AI9595
 AI9595.The orthometric height was determined by differential leveling and
 AI9595.adjusted by the NATIONAL GEODETIC SURVEY
 AI9595.in July 2002.
 AI9595
 AI9595.No vertical observational check was made to the station.
 AI9595
 AI9595.Significant digits in the geoid height do not necessarily reflect accuracy.
 AI9595.GEOID18 height accuracy estimate available here.
 AI9595
 AI9595.Click photographs - Photos may exist for this station.
 AI9595
 AI9595.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 AI9595
 AI9595.The Laplace correction was computed from DEFLEC18 derived deflections.
 AI9595
 AI9595.The ellipsoidal height was determined by GPS observations
 AI9595.and is referenced to NAD 83.
 AI9595
 AI9595.The dynamic height is computed by dividing the NAVD 88
 AI9595.geopotential number by the normal gravity value computed on the
 AI9595.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 AI9595.degrees latitude (g = 980.6199 gals.).
 AI9595
 AI9595.The modeled gravity was interpolated from observed gravity values.
 AI9595
 AI9595. The following values were computed from the NAD 83(2011) position.

 HV2752'END OF RUNWAY 1L-19R AND 1.0208 FEETWEST OF THE RUNWAY CENTERLINE.
 HV2752'ACCESS IS UNAUTHORIZED WITHOUT CLEARANCE FROM DULLES AIRPORT
 HV2752'OPERATIONS, RUNWAY SHUTDOWN, AND AN ESCORT.  THE MARK IS A STANDARD
 HV2752'CGS TRIANGULATION STATION DISK STAMPED DULLES 36L 1960.  IT IS
 HV2752'CEMENTED IN A DRILL HOLE IN THE CONCRETE RUNWAY.  THIS MONUMENT IS THE
 HV2752'ORIGIN OF THE DULLES AIRPORT COORDINATE SYSTEM (ACS) .  BOTH THE
 HV2752'X-AXIS AND THE Y-AXIS OF THE ACS GRID PASS THROUGH THIS POINT.  THE
 HV2752'ACS Y-COORDINATE OF THIS MONUMENT HAS A FALSE NORTHING OF 100,000.000
 HV2752'FEET, AND THE ACS X-COORDINATE HAS A FALSE EASTING OF 99,998.979 FEET.
 HV2752'THE Y-AXIS OF THE DULLES ACS ALSO PASSES THROUGH MONUMENT DULLES 18R
 HV2752'(AT THE NORTH END OF THE RUNWAY) AND ALSO HAS A FALSE EASTING OF
 HV2752'99,998.979 SO THAT ALL X-COORDINATES OF 100,000 FEET EXACTLY ARE
 HV2752'COINCIDENT WITH THE CENTERLINE OF WITH THE CENTERLINE OF RUNWAY 1L-19R
 HV2752'AND SO THAT DISTANCES EAST/WEST OF THIS RUNWAY CAN BE EASILY
 HV2752'DETERMINED.  THE PROJECTION PLANE IS SECANT TO THE ELLIPSOID SO THAT
 HV2752'THE AVERAGE SCALE FACTOR FOR THE DULLES AIRPORT COORDINATE SYSTEM IS
 HV2752'1.0000000.

 FX3989'ON NANSEMOND RIVER, ON PROPERTY OWNED BY L.J. UPTON AND
 FX3989'OPERATED BY J.U. GREGORY, ON A STEEP 20-FOOT EMBANKMENT,
 FX3989'131 FEET TOWARDS STATION SACK TO THE SHORE OF A 30-FOOT ARM
 FX3989'OF THE NANSEMOND RIVER AND 483 FEET FROM SOUTHWEST CORNER
 FX3989'OF AN L-SHAPED ONE-STORY FRAME HOUSE.
 FX3989'
 FX3989'THE PLACE IS REACHED FROM SUFFOLK BY PROCEEDING ALONG THE
 FX3989'ROAD TOWARD DRIVERS TO A POINT 3-1/2 MILES AFTER PASSING
 FX3989'THROUGH MAGNOLIA.  THERE IS A STRAIGHT DIRT ROAD LEADING LEFT
 FX3989'FROM THIS PLACE, AND AN OAK TREE 4 FEET IN DIAMETER WHERE
 FX3989'THE ROADS JOIN.  FOLLOW THE ROAD ABOUT 0.7 MILE TO THE FARM
 FX3989'BUILDINGS OF MR. GREGORY, AND TURN RIGHT ONTO A LANE JUST
 FX3989'BEFORE REACHING THE BARN.  THIS LANE LEADS TO A HOUSE
 FX3989'FROM WHICH THE MONUMENT IS 150 METERS DISTANT ACROSS A FIELD
 FX3989'TOWARD THE RIVER.
 FX3989'
 FX3989'THE MARK IS A STANDARD DISK EMBEDDED IN CONCRETE WHICH IS
 FX3989'IN TURN EMBEDDED IN A 4-FOOT GUMWOOD STUMP PROTRUDING 3
 FX3989'FEET ABOVE THE GROUND.  THE STUMP IS ABOUT HALF-WAY UP THE
 FX3989'SIDE OF THE EMBANKMENT IN THE HEAVY FRINGE OF TREES.
 FX3989'
 FX3989'REFERENCE MARKS ARE STANDARD BRONZE DISKS SET IN CONCRETE
 FX3989'AS DESCRIBED, BOTH IN A PLOWED FIELD ON THE
 FX3989'EDGE OF BRUSH LAND.

 FX3989'BY TALL TREES WAS VISITED, AND A THOROUGH SEARCH MADE ALL
 FX3989'AROUND THE POINT OF LAND, BOTH IN THE FIELD AND TREES AND
 FX3989'IN THE MARSH.  NO EVIDENC OF A FOUR-FOOT STUMP COULD BE FOUND.
 FX3989'THE FIELD IS OVERGROWN WITH WEEDS AND IT IS POSSIBLE THAT
 FX3989'REFERENCE MARKS COULD BE RECOVERED AT A DIFFERENT SEASON
 FX3989'OF THE YEAR.

 GV4310'DESCRIBED BY COAST AND GEODETIC SURVEY 1906 (WB)
 GV4310'THIS STATION IS LOCATED ON ELLEN ISLAND NEAR THE N SHORE OF THE
 GV4310'YORK RIVER.  THIS ISLAND IS NOW GENERALLY KNOWN AS ALLEN ISLAND,
 GV4310'ALTHOUGH ELLEN IS ITS OLD NAME.  THE ISLAND IS MOSTLY MARSH WITH
 GV4310'SOME SANDY PORTIONS.  ON ONE OF THE LATTER (SANDY PORTIONS)
 GV4310'NEAR THE S SIDE OF THE ISLAND IS A GROVE OF PINE TREES.  THE
 GV4310'STATION IS JUST TO THE S OF THIS GROVE AND ABOUT 15 METERS FROM THE
 GV4310'SHORE.
 GV4310'
 GV4310'THE STATION WAS MARKED BY A TERRA-COTTA PIPE 2 FEET LONG, 4 INCHES
 GV4310'IN DIAMETER, AND WAS CENTERED UNDER STATION WITH TOP ABOUT 23
 GV4310'INCHES BELOW SURFACE OF GROUND.  ABOVE THIS WAS PLACED ABOUT 6
 GV4310'INCHES OF SAND.  UPON THIS WAS CENTERED ANOTHER TERRA-COTTA
 GV4310'PIPE WHICH WAS FILLED WITH CEMENT AND SURROUNDED BY A COLUMN OF
 GV4310'CEMENT ABOUT 20 INCHES IN DIAMETER AND WITH TOP OF COLUMN FLUSH
 GV4310'WITH THE SURFACE OF THE GROUND.  TOP OF PIPE USED FOR SURFACE
 GV4310'MARK EXTENDS 6 INCHES ABOVE GROUND.  THE PIPES WERE PLUMBED
 GV4310'AND THEIR CENTERS MARK STATION.
 GV4310'
 GV4310'THE REFERENCE MARKS ARE TRIANGLES CUT INTO THE BARK OF THREE PINE
 GV4310'TREES.
