 BG2536.an estimated accuracy of +/- 6 seconds.
 BG2536
 BG2536.** This station is in an area of known vertical motion.  Due to the
 BG2536.** variability of land subsidence, uplift, and crustal motion, NGS has,
 BG2536.** determined the orthometric heights for marks in these suspect
 BG2536.** subsidence areas should be considered valid only at the epoch date
 BG2536.** associated with the orthometric height.  These heights must always
 BG2536.** be validated when used as control.  All previously superseded
 BG2536.** orthometric heights are now considered suspect and are available
 BG2536.** in the superseded section.  NGS does not recommend using suspect
 BG2536.** or superseded heights as control.
 BG2536
 BG2536.The orthometric height was determined by differential leveling and
 BG2536.adjusted by the NATIONAL GEODETIC SURVEY
 BG2536.in July 2012.

 AB4076.** This station is in an area of known vertical motion.  Due to the
 AB4076.** variability of land subsidence, uplift, and crustal motion, NGS has,
 AB4076.** determined the orthometric heights for marks in these suspect
 AB4076.** subsidence areas should be considered valid only at the epoch date
 AB4076.** associated with the orthometric height.  These heights must always
 AB4076.** be validated when used as control.  All previously superseded
 AB4076.** orthometric heights are now considered suspect and are available
 AB4076.** in the superseded section.  NGS does not recommend using suspect
 AB4076.** or superseded heights as control.

 BG5016.** This station is in an area of known vertical motion.  Due to the
 BG5016.** variability of land subsidence, uplift, and crustal motion, NGS has,
 BG5016.** determined the orthometric heights for marks in these suspect
 BG5016.** subsidence areas should be considered valid only at the epoch date
 BG5016.** associated with the orthometric height.  These heights must always
 BG5016.** be validated when used as control.  All previously superseded
 BG5016.** orthometric heights are now considered suspect and are available
 BG5016.** in the superseded section.  NGS does not recommend using suspect
 BG5016.** or superseded heights as control.
 BG5016
 BG5016.The orthometric height was determined by differential leveling and

 BG5018.** This station is in an area of known vertical motion.  Due to the
 BG5018.** variability of land subsidence, uplift, and crustal motion, NGS has,
 BG5018.** determined the orthometric heights for marks in these suspect

 BG5018.** associated with the orthometric height.  These heights must always
 BG5018.** be validated when used as control.  All previously superseded
 BG5018.** orthometric heights are now considered suspect and are available
 BG5018.** in the superseded section.  NGS does not recommend using suspect
 BG5018.** or superseded heights as control.

 BG5020.The horizontal coordinates were established by GPS observations
 BG5020.and adjusted by the National Geodetic Survey in June 2012.
 BG5020
 BG5020.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 BG5020.been affixed to the stable North American tectonic plate. See 
 BG5020.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 BG5020
 BG5020.The horizontal coordinates are valid at the epoch date displayed above
 BG5020.which is a decimal equivalence of Year/Month/Day.
 BG5020
 BG5020.** This station is in an area of known vertical motion.  Due to the
 BG5020.** variability of land subsidence, uplift, and crustal motion, NGS has,
 BG5020.** determined the orthometric heights for marks in these suspect
 BG5020.** subsidence areas should be considered valid only at the epoch date
 BG5020.** associated with the orthometric height.  These heights must always
 BG5020.** be validated when used as control.  All previously superseded
 BG5020.** orthometric heights are now considered suspect and are available
 BG5020.** in the superseded section.  NGS does not recommend using suspect
 BG5020.** or superseded heights as control.
 BG5020
 BG5020.The orthometric height was determined by differential leveling and
 BG5020.adjusted by the NATIONAL GEODETIC SURVEY
 BG5020.in August 2012.
 BG5020
 BG5020.No vertical observational check was made to the station.
 BG5020
 BG5020.Significant digits in the geoid height do not necessarily reflect accuracy.
 BG5020.GEOID18 height accuracy estimate available here.

 BG5020.Click photographs - Photos may exist for this station.
 BG5020
 BG5020.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 BG5020
 BG5020.The Laplace correction was computed from DEFLEC18 derived deflections.
 BG5020
 BG5020.The ellipsoidal height was determined by GPS observations
 BG5020.and is referenced to NAD 83.
 BG5020
 BG5020.The dynamic height is computed by dividing the NAVD 88
 BG5020.geopotential number by the normal gravity value computed on the
 BG5020.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 BG5020.degrees latitude (g = 980.6199 gals.).

 AA2157
 AA2157.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 AA2157.been affixed to the stable North American tectonic plate. See 
 AA2157.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 AA2157
 AA2157.The horizontal coordinates are valid at the epoch date displayed above
 AA2157.which is a decimal equivalence of Year/Month/Day.
 AA2157
 AA2157.** This station is in an area of known vertical motion.  Due to the
 AA2157.** variability of land subsidence, uplift, and crustal motion, NGS has,
 AA2157.** determined the orthometric heights for marks in these suspect

 AA2157.** associated with the orthometric height.  These heights must always
 AA2157.** be validated when used as control.  All previously superseded
 AA2157.** orthometric heights are now considered suspect and are available
 AA2157.** in the superseded section.  NGS does not recommend using suspect
 AA2157.** or superseded heights as control.
 AA2157
 AA2157.The orthometric height was determined by differential leveling and
 AA2157.adjusted by the NATIONAL GEODETIC SURVEY
 AA2157.in July 2012.
 AA2157
 AA2157.No vertical observational check was made to the station.

 AA2157
 AA2157.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 AA2157
 AA2157.The Laplace correction was computed from DEFLEC18 derived deflections.
 AA2157
 AA2157.The ellipsoidal height was determined by GPS observations
 AA2157.and is referenced to NAD 83.
 AA2157
 AA2157.The dynamic height is computed by dividing the NAVD 88
 AA2157.geopotential number by the normal gravity value computed on the
 AA2157.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 AA2157.degrees latitude (g = 980.6199 gals.).

 AA2175.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 AA2175.been affixed to the stable North American tectonic plate. See 
 AA2175.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 AA2175
 AA2175.The horizontal coordinates are valid at the epoch date displayed above
 AA2175.which is a decimal equivalence of Year/Month/Day.
 AA2175
 AA2175.** This station is in an area of known vertical motion.  Due to the
 AA2175.** variability of land subsidence, uplift, and crustal motion, NGS has,
 AA2175.** determined the orthometric heights for marks in these suspect
 AA2175.** subsidence areas should be considered valid only at the epoch date
 AA2175.** associated with the orthometric height.  These heights must always
 AA2175.** be validated when used as control.  All previously superseded
 AA2175.** orthometric heights are now considered suspect and are available
 AA2175.** in the superseded section.  NGS does not recommend using suspect
 AA2175.** or superseded heights as control.
 AA2175
 AA2175.The orthometric height was determined by differential leveling and
 AA2175.adjusted by the NATIONAL GEODETIC SURVEY
 AA2175.in July 2012.
 AA2175
 AA2175.No vertical observational check was made to the station.

 AA2175.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 AA2175
 AA2175.The Laplace correction was computed from DEFLEC18 derived deflections.
 AA2175
 AA2175.The ellipsoidal height was determined by GPS observations
 AA2175.and is referenced to NAD 83.
 AA2175
 AA2175.The dynamic height is computed by dividing the NAVD 88
 AA2175.geopotential number by the normal gravity value computed on the
 AA2175.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 AA2175.degrees latitude (g = 980.6199 gals.).
 AA2175
 AA2175.The modeled gravity was interpolated from observed gravity values.

 BU2002.The horizontal coordinates were established by GPS observations
 BU2002.and adjusted by the National Geodetic Survey in June 2012.
 BU2002
 BU2002.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 BU2002.been affixed to the stable North American tectonic plate. See 
 BU2002.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 BU2002
 BU2002.The horizontal coordinates are valid at the epoch date displayed above
 BU2002.which is a decimal equivalence of Year/Month/Day.
 BU2002
 BU2002.The orthometric height was determined by differential leveling
 BU2002.and adjusted by the NATIONAL GEODETIC SURVEY in September 1998.
 BU2002
 BU2002.The height was determined by precise leveling from only one NSRS
 BU2002.bench mark.  This was not adequate 'tie leveling' to NSRS and was
 BU2002.allowed ONLY to validate the GPS-derived height.
 BU2002
 BU2002.Significant digits in the geoid height do not necessarily reflect accuracy.
 BU2002.GEOID18 height accuracy estimate available here.

 BU2002.Click photographs - Photos may exist for this station.
 BU2002
 BU2002.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 BU2002
 BU2002.The Laplace correction was computed from DEFLEC18 derived deflections.
 BU2002
 BU2002.The ellipsoidal height was determined by GPS observations
 BU2002.and is referenced to NAD 83.
 BU2002
 BU2002.The dynamic height is computed by dividing the NAVD 88
 BU2002.geopotential number by the normal gravity value computed on the
 BU2002.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 BU2002.degrees latitude (g = 980.6199 gals.).
 BU2002
 BU2002.The modeled gravity was interpolated from observed gravity values.

 BU2183'RECOVERY NOTE BY TROY STATE UNIVERSITY 2022 (NWH)
 BU2183'THE MARK WAS NOT FOUND.  THE MEASURED LOCATION OF THE MARK (FROM THE
 BU2183'ROAD CENTERLINE) PLACES THE MARK UNDER THE EDGE OF A PINE PLANTATION.
 BU2183'THE MEASURED LOCATION IS ALSO ON THE EDGE OF THE ROAD WORK FOR THE
 BU2183'ROADSIDE DRAIN, SO MAY HAVE BEEN AFFECTED BY THE ROPAD WORK, OR IT MAY
 BU2183'HAVE BEEN RIPPED OUT DURING THE PREPARATION FOR PLANTING THE PINE
 BU2183'PLANTATION.  THE WITNESS POST IS GONE.  THE SEARCH FOR THE MARK
 BU2183'STOPPED WHEN IT WAS CLEAR THAT THE MARK WAS UNDER THE EDGE OF THE
 BU2183'PLANTATION AND WAS PROBABLY REMOVED BY EARTH WORK IN THE PAST.

 EE2320.The orthometric height was determined by differential leveling
 EE2320.and adjusted by the NATIONAL GEODETIC SURVEY in September 1998.
 EE2320
 EE2320.The height was determined by precise leveling from only one NSRS

 CN3328.and adjusted by the NATIONAL GEODETIC SURVEY in July 1998.
 CN3328
 CN3328.The height was determined by precise leveling from only one NSRS
 CN3328.bench mark.  This was not adequate 'tie leveling' to NSRS and was
 CN3328.allowed ONLY to validate the GPS-derived height.
 CN3328
 CN3328.Significant digits in the geoid height do not necessarily reflect accuracy.
 CN3328.GEOID18 height accuracy estimate available here.

 CN3328.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 CN3328
 CN3328.The Laplace correction was computed from DEFLEC18 derived deflections.
 CN3328
 CN3328.The ellipsoidal height was determined by GPS observations
 CN3328.and is referenced to NAD 83.
 CN3328
 CN3328.The dynamic height is computed by dividing the NAVD 88
 CN3328.geopotential number by the normal gravity value computed on the
 CN3328.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 CN3328.degrees latitude (g = 980.6199 gals.).
 CN3328
 CN3328.The modeled gravity was interpolated from observed gravity values.

 BT2236.The horizontal coordinates were established by GPS observations
 BT2236.and adjusted by the National Geodetic Survey in June 2012.
 BT2236
 BT2236.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 BT2236.been affixed to the stable North American tectonic plate. See 
 BT2236.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 BT2236
 BT2236.The horizontal coordinates are valid at the epoch date displayed above
 BT2236.which is a decimal equivalence of Year/Month/Day.
 BT2236
 BT2236.The orthometric height was determined by differential leveling
 BT2236.and adjusted by the NATIONAL GEODETIC SURVEY in September 1998.
 BT2236
 BT2236.The height was determined by precise leveling from only one NSRS
 BT2236.bench mark.  This was not adequate 'tie leveling' to NSRS and was
 BT2236.allowed ONLY to validate the GPS-derived height.
 BT2236
 BT2236.Significant digits in the geoid height do not necessarily reflect accuracy.

 BT2236.The Laplace correction was computed from DEFLEC18 derived deflections.
 BT2236
 BT2236.The ellipsoidal height was determined by GPS observations
 BT2236.and is referenced to NAD 83.
 BT2236
 BT2236.The dynamic height is computed by dividing the NAVD 88
 BT2236.geopotential number by the normal gravity value computed on the
 BT2236.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 BT2236.degrees latitude (g = 980.6199 gals.).

 DH2742
 DH2742.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 DH2742.been affixed to the stable North American tectonic plate. See 
 DH2742.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 DH2742
 DH2742.The horizontal coordinates are valid at the epoch date displayed above
 DH2742.which is a decimal equivalence of Year/Month/Day.
 DH2742
 DH2742.The orthometric height was determined by differential leveling
 DH2742.and adjusted by the NATIONAL GEODETIC SURVEY in September 1998.
 DH2742
 DH2742.The height was determined by precise leveling from only one NSRS
 DH2742.bench mark.  This was not adequate 'tie leveling' to NSRS and was
 DH2742.allowed ONLY to validate the GPS-derived height.
 DH2742
 DH2742.Significant digits in the geoid height do not necessarily reflect accuracy.

 DH2742.The Laplace correction was computed from DEFLEC18 derived deflections.
 DH2742
 DH2742.The ellipsoidal height was determined by GPS observations
 DH2742.and is referenced to NAD 83.
 DH2742
 DH2742.The dynamic height is computed by dividing the NAVD 88
 DH2742.geopotential number by the normal gravity value computed on the
 DH2742.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 DH2742.degrees latitude (g = 980.6199 gals.).

 DH2780.The horizontal coordinates were established by GPS observations
 DH2780.and adjusted by the National Geodetic Survey in June 2012.
 DH2780
 DH2780.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 DH2780.been affixed to the stable North American tectonic plate. See 
 DH2780.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 DH2780
 DH2780.The horizontal coordinates are valid at the epoch date displayed above
 DH2780.which is a decimal equivalence of Year/Month/Day.
 DH2780
 DH2780.The orthometric height was determined by differential leveling
 DH2780.and adjusted by the NATIONAL GEODETIC SURVEY in September 1998.
 DH2780
 DH2780.The height was determined by precise leveling from only one NSRS
 DH2780.bench mark.  This was not adequate 'tie leveling' to NSRS and was
 DH2780.allowed ONLY to validate the GPS-derived height.
 DH2780
 DH2780.Significant digits in the geoid height do not necessarily reflect accuracy.
 DH2780.GEOID18 height accuracy estimate available here.

 DH2780.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 DH2780
 DH2780.The Laplace correction was computed from DEFLEC18 derived deflections.
 DH2780
 DH2780.The ellipsoidal height was determined by GPS observations
 DH2780.and is referenced to NAD 83.
 DH2780
 DH2780.The dynamic height is computed by dividing the NAVD 88
 DH2780.geopotential number by the normal gravity value computed on the
 DH2780.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 DH2780.degrees latitude (g = 980.6199 gals.).

 EF0691'RECOVERY NOTE BY TROY STATE UNIVERSITY 2022 (NWH)
 EF0691'THE MARK WAS NOT FOUND.  THE STATION IS GONE AND THE AREA WHERE THE
 EF0691'RAIL LINE USED TO BE IS MOSTLY PLOWED UP OR UNDER A ROADWAY.  A
 EF0691'SECTION OF THE RAIL EMBANKMENT AT AROUND THE LATITUDE AND LONGITUDE
 EF0691'LOCATION IS STILL THERE AND A WIDE CULVERT WAS FOUND THAT WOULD HAVE
 EF0691'BEEN UNDER A SECTION OF DOUBLE TRACK, AS WAS IN THE AREA AT THE TIME.
 EF0691'THERE IS AN AREA OF TREES AROUND THE REMAINS OF THIS EMBANKMENT, BUT
 EF0691'IT IS NOT AT ALL APPARENT WHERE THE STATION MAY HAVE BEEN.  NO STEEL
 EF0691'FENCE POST WAS FOUND AND THE MARK WAS NOT SEEN.  THE DESCRIPTION DOES
 EF0691'NOT MENTION WHICH SIDE OF THE TRACKS THE MARK IS LOCATED, ALTHOUGH AN
 EF0691'OLD TOPOGRAPHIC MAP SUGGESTS THE WEST SIDE.  THERE ARE NO OTHER
 EF0691'APPARENT REFERENCE MARKS.  IF THE MARK IS NORTH OF THE ROAD THAT HEADS
 EF0691'DOWN TO THE RIVER (BILL MATTHEWS ROAD ON MAPS), IT WILL BE UNDER
 EF0691'TREES.

 EF1776.The horizontal coordinates were established by GPS observations
 EF1776.and adjusted by the National Geodetic Survey in June 2012.
 EF1776
 EF1776.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 EF1776.been affixed to the stable North American tectonic plate. See 
 EF1776.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 EF1776
 EF1776.The horizontal coordinates are valid at the epoch date displayed above
 EF1776.which is a decimal equivalence of Year/Month/Day.
 EF1776
 EF1776.The orthometric height was determined by differential leveling and
 EF1776.adjusted by the NATIONAL GEODETIC SURVEY
 EF1776.in February 2008.

 EF1776.The Laplace correction was computed from DEFLEC18 derived deflections.
 EF1776
 EF1776.The ellipsoidal height was determined by GPS observations
 EF1776.and is referenced to NAD 83.
 EF1776
 EF1776.The dynamic height is computed by dividing the NAVD 88
 EF1776.geopotential number by the normal gravity value computed on the
 EF1776.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45

 AA2425'RECOVERY NOTE BY TROY STATE UNIVERSITY 2022 (NWH)
 AA2425'THE MARK WAS FOUND IN GOOD CONDITION, AS PREVIOUSLY DESCRIBED.  THE
 AA2425'CARBONITE WITNESS POST IS GONE, BUT THERE IS A WITNESS PLATE ATTACHED
 AA2425'TO THE ADJACENT POWER POLE.  THE MARK IS 1.4 FT (0.4 M) SOUTHWEST OF A
 AA2425'RECENT WOODEN POLE WITH A SINGLE GUY, THAT IS CARRYING PHONE AND CABLE
 AA2425'LINES AND HAS A ROUND WHITE PVC CABLE CONNECTION CONTAINER ON ITS
 AA2425'SOUTHERN SIDE.  THE MARK HAS HAD GPS MEASUREMENTS IN THE PAST, BUT AT
 AA2425'THAT TIME THE POLE WAS NOT SO CLOSE.  SO THERE MAY BE SOME QUESTION
 AA2425'OVER THE QUALITY OF GPS OBSERVATIONS IN THE FUTURE.

 AA2260.** This station is in an area of known vertical motion.  Due to the
 AA2260.** variability of land subsidence, uplift, and crustal motion, NGS has,
 AA2260.** determined the orthometric heights for marks in these suspect

 AA2272
 AA2272.The horizontal coordinates are valid at the epoch date displayed above
 AA2272.which is a decimal equivalence of Year/Month/Day.
 AA2272
 AA2272.** This station is in an area of known vertical motion.  Due to the
 AA2272.** variability of land subsidence, uplift, and crustal motion, NGS has,
 AA2272.** determined the orthometric heights for marks in these suspect
 AA2272.** subsidence areas should be considered valid only at the epoch date
 AA2272.** associated with the orthometric height.  These heights must always
 AA2272.** be validated when used as control.  All previously superseded
 AA2272.** orthometric heights are now considered suspect and are available
 AA2272.** in the superseded section.  NGS does not recommend using suspect
 AA2272.** or superseded heights as control.
 AA2272
 AA2272.The orthometric height was determined by differential leveling and
 AA2272.adjusted by the NATIONAL GEODETIC SURVEY
 AA2272.in July 2012.
 AA2272
 AA2272.No vertical observational check was made to the station.

 EF0706'RECOVERY NOTE BY TROY STATE UNIVERSITY 2022 (NWH)
 EF0706'THE MARK WAS NOT FOUND.  A SYCAMORE TREE WAS FOUND, POSSIBLY OLD
 EF0706'ENOUGH TO BE THE ONE CITED, BUT IT WAS LEANING INTO THE RIVER AS THE
 EF0706'BANK HAD COLLAPSED BENEATH IT.  THERE WAS NO SIGN OF CONCRETE TO THE
 EF0706'NORTH OF THE TREE.  THE BANK IS ERODED ALONG THIS SECTION AND IT IS 5
 EF0706'TO 10 FT (3.0 M) FROM THE WATER TO THE CREST OF THE BANK.  THERE IS A
 EF0706'LOT OF RIP-RAP ALONG THE BANK.  THE MARK MAY HAVE ERODED INTO THE
 EF0706'RIVER.  MORE EXPERIENCED PEOPLE ALONG THE RIVER SUGGEST THAT THE MARK
 EF0706'IS GONE.

 DH2810.The horizontal coordinates were established by GPS observations
 DH2810.and adjusted by the National Geodetic Survey in June 2012.
 DH2810
 DH2810.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 DH2810.been affixed to the stable North American tectonic plate. See 
 DH2810.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 DH2810
 DH2810.The horizontal coordinates are valid at the epoch date displayed above
 DH2810.which is a decimal equivalence of Year/Month/Day.
 DH2810
 DH2810.The orthometric height was determined by differential leveling
 DH2810.and adjusted by the NATIONAL GEODETIC SURVEY in February 1996.
 DH2810
 DH2810.The height was determined by precise leveling from only one NSRS
 DH2810.bench mark.  This was not adequate 'tie leveling' to NSRS and was
 DH2810.allowed ONLY to validate the GPS-derived height.

 DJ2136.The horizontal coordinates were established by GPS observations
 DJ2136.and adjusted by the National Geodetic Survey in June 2012.
 DJ2136
 DJ2136.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 DJ2136.been affixed to the stable North American tectonic plate. See 
 DJ2136.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 DJ2136
 DJ2136.The horizontal coordinates are valid at the epoch date displayed above
 DJ2136.which is a decimal equivalence of Year/Month/Day.
 DJ2136
 DJ2136.The orthometric height was determined by differential leveling
 DJ2136.and adjusted by the NATIONAL GEODETIC SURVEY in February 1996.
 DJ2136
 DJ2136.The height was determined by precise leveling from only one NSRS
 DJ2136.bench mark.  This was not adequate 'tie leveling' to NSRS and was
 DJ2136.allowed ONLY to validate the GPS-derived height.
 DJ2136
 DJ2136.Significant digits in the geoid height do not necessarily reflect accuracy.
 DJ2136.GEOID18 height accuracy estimate available here.

 DJ2136.Click photographs - Photos may exist for this station.
 DJ2136
 DJ2136.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 DJ2136
 DJ2136.The Laplace correction was computed from DEFLEC18 derived deflections.
 DJ2136
 DJ2136.The ellipsoidal height was determined by GPS observations
 DJ2136.and is referenced to NAD 83.
 DJ2136
 DJ2136.The dynamic height is computed by dividing the NAVD 88
 DJ2136.geopotential number by the normal gravity value computed on the
 DJ2136.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 DJ2136.degrees latitude (g = 980.6199 gals.).
 DJ2136
 DJ2136.The modeled gravity was interpolated from observed gravity values.

 CO1602.The horizontal coordinates were established by GPS observations
 CO1602.and adjusted by the National Geodetic Survey in June 2012.
 CO1602
 CO1602.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 CO1602.been affixed to the stable North American tectonic plate. See 
 CO1602.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 CO1602
 CO1602.The horizontal coordinates are valid at the epoch date displayed above
 CO1602.which is a decimal equivalence of Year/Month/Day.
 CO1602
 CO1602.The orthometric height was determined by differential leveling
 CO1602.and adjusted by the NATIONAL GEODETIC SURVEY in February 1996.
 CO1602
 CO1602.The height was determined by precise leveling from only one NSRS
 CO1602.bench mark.  This was not adequate 'tie leveling' to NSRS and was
 CO1602.allowed ONLY to validate the GPS-derived height.
 CO1602
 CO1602.Significant digits in the geoid height do not necessarily reflect accuracy.
 CO1602.GEOID18 height accuracy estimate available here.

 CO1602.The Laplace correction was computed from DEFLEC18 derived deflections.
 CO1602
 CO1602.The ellipsoidal height was determined by GPS observations
 CO1602.and is referenced to NAD 83.
 CO1602
 CO1602.The dynamic height is computed by dividing the NAVD 88
 CO1602.geopotential number by the normal gravity value computed on the
 CO1602.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 CO1602.degrees latitude (g = 980.6199 gals.).

 CM2482'RECOVERY NOTE BY TROY STATE UNIVERSITY 2022 (NWH)
 CM2482'THE MARK WAS FOUND IN GOOD CONDITION, AS PREVIOUSLY DESCRIBED.  THE
 CM2482'WITNESS POST IS GONE AND THE AREA AROUND THE MARK IS NICELY KEPT LAWN
 CM2482'IN FRONT OF A GROVE OF PECAN TREES.  THE PAVED COUNTY ROAD PASSING BY
 CM2482'THE MARK IS SOUTH TALLASSEE DRIVE, ALSO TALLAPOOSA COUNTY ROAD 4.  THE
 CM2482'MARK HAS A STRONG MAGNETIC SIGNAL AND THERE DOES NOT APPEAR TO BE
 CM2482'ANYTHING AS STRONG NEAR IT, MAKING IT EASY TO FIND WITH A MAGNETIC
 CM2482'DETECTOR.  THE MARK IS WELL CLEAR OF NEARBY TREES GIVING IT A GOOD SKY
 CM2482'VIEW FOR GPS OBSERVATIONS.

 DH2760.The horizontal coordinates were established by GPS observations
 DH2760.and adjusted by the National Geodetic Survey in June 2012.
 DH2760
 DH2760.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 DH2760.been affixed to the stable North American tectonic plate. See 
 DH2760.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 DH2760
 DH2760.The horizontal coordinates are valid at the epoch date displayed above
 DH2760.which is a decimal equivalence of Year/Month/Day.
 DH2760
 DH2760.The orthometric height was determined by differential leveling
 DH2760.and adjusted by the NATIONAL GEODETIC SURVEY in September 1998.
 DH2760
 DH2760.The height was determined by precise leveling from only one NSRS
 DH2760.bench mark.  This was not adequate 'tie leveling' to NSRS and was
 DH2760.allowed ONLY to validate the GPS-derived height.

 DH2760
 DH2760.The ellipsoidal height was determined by GPS observations
 DH2760.and is referenced to NAD 83.
 DH2760
 DH2760.The dynamic height is computed by dividing the NAVD 88
 DH2760.geopotential number by the normal gravity value computed on the
 DH2760.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45

 BV1860.** This station is in an area of known vertical motion.  Due to the
 BV1860.** variability of land subsidence, uplift, and crustal motion, NGS has,
 BV1860.** determined the orthometric heights for marks in these suspect
 BV1860.** subsidence areas should be considered valid only at the epoch date
 BV1860.** associated with the orthometric height.  These heights must always
 BV1860.** be validated when used as control.  All previously superseded
 BV1860.** orthometric heights are now considered suspect and are available
 BV1860.** in the superseded section.  NGS does not recommend using suspect
 BV1860.** or superseded heights as control.
 BV1860
 BV1860.** The orthometric height was determined with a Vertical Time-dependent
 BV1860.** Positioning (VTDP) model and has been validated through GNSS
 BV1860.** observations for the epoch indicated.  For additional

 AA8496.The horizontal coordinates were established by GPS observations
 AA8496.and adjusted by the National Geodetic Survey in June 2012.
 AA8496
 AA8496.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 AA8496.been affixed to the stable North American tectonic plate. See 
 AA8496.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 AA8496
 AA8496.The horizontal coordinates are valid at the epoch date displayed above
 AA8496.which is a decimal equivalence of Year/Month/Day.
 AA8496
 AA8496.The orthometric height was determined by differential leveling and
 AA8496.adjusted by the NATIONAL GEODETIC SURVEY
 AA8496.in July 2008.
 AA8496
 AA8496.No vertical observational check was made to the station.
 AA8496
 AA8496.Significant digits in the geoid height do not necessarily reflect accuracy.
 AA8496.GEOID18 height accuracy estimate available here.
 AA8496
 AA8496.Click photographs - Photos may exist for this station.
 AA8496
 AA8496.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 AA8496
 AA8496.The Laplace correction was computed from DEFLEC18 derived deflections.
 AA8496
 AA8496.The ellipsoidal height was determined by GPS observations
 AA8496.and is referenced to NAD 83.
 AA8496
 AA8496.The dynamic height is computed by dividing the NAVD 88
 AA8496.geopotential number by the normal gravity value computed on the
 AA8496.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 AA8496.degrees latitude (g = 980.6199 gals.).
 AA8496
 AA8496.The modeled gravity was interpolated from observed gravity values.

 BU2104.The orthometric height was determined by differential leveling
 BU2104.and adjusted by the NATIONAL GEODETIC SURVEY in February 1996.
 BU2104
 BU2104.The height was determined by precise leveling from only one NSRS
 BU2104.bench mark.  This was not adequate 'tie leveling' to NSRS and was
 BU2104.allowed ONLY to validate the GPS-derived height.

 BU2025.The orthometric height was determined by differential leveling
 BU2025.and adjusted by the NATIONAL GEODETIC SURVEY in September 1998.
 BU2025
 BU2025.The height was determined by precise leveling from only one NSRS
 BU2025.bench mark.  This was not adequate 'tie leveling' to NSRS and was
 BU2025.allowed ONLY to validate the GPS-derived height.

 EF1154'THE MARK WAS NOT FOUND AND PRESUMED DESTROYED.   THE BRIDGE IS GONE
 EF1154'AND THERE IS A DEEP BODY OF WATER REMAINING.  AT AROUND 115 YDS (105.2
 EF1154'M) WEST OF THE SITE OF THE OLD BRIDGE IS A ROCK OUTCROP OVER WHICH THE
 EF1154'ROAD IS LOCATED AND TO THE NORTHEAST THE GROUND IS MUCH LOWER, SO THE

 DL8943.** This station is in an area of known vertical motion.  Due to the
 DL8943.** variability of land subsidence, uplift, and crustal motion, NGS has,
 DL8943.** determined the orthometric heights for marks in these suspect
 DL8943.** subsidence areas should be considered valid only at the epoch date
 DL8943.** associated with the orthometric height.  These heights must always
 DL8943.** be validated when used as control.  All previously superseded
 DL8943.** orthometric heights are now considered suspect and are available
 DL8943.** in the superseded section.  NGS does not recommend using suspect
 DL8943.** or superseded heights as control.
 DL8943
 DL8943.The orthometric height was determined by differential leveling and
 DL8943.adjusted by the NATIONAL GEODETIC SURVEY
 DL8943.in July 2012.

 DN4791.** This station is in an area of known vertical motion.  Due to the
 DN4791.** variability of land subsidence, uplift, and crustal motion, NGS has,

 DN4791.** subsidence areas should be considered valid only at the epoch date
 DN4791.** associated with the orthometric height.  These heights must always
 DN4791.** be validated when used as control.  All previously superseded

 DM3977.Formal positional accuracy estimates are not available for this CORS
 DM3977.because its coordinates were determined in part using modeled velocities.
 DM3977.A time-series residual plot is available that shows daily coordinate
 DM3977.variations relative to the published coordinates and modeled velocities.
 DM3977.Large residuals may indicate a potential error in the modeled velocities.

 DM3977.NGS completed the third reprocessing of daily RINEX data from 1996 to 2022
 DM3977.for all stations in the NOAA CORS Network (NCN).  The reprocessed solution,
 DM3977.known as the Multi-Year CORS Solution 3 (MYCS3), is aligned with the
 DM3977.ITFR2020 global frame, epoch 2020.00.  The resulting MYCS3 coordinates
 DM3977.were then transformed to NAD83(2011/MA11/PA11), maintaining the currently
 DM3977.published epoch of 2010.00.

 DI3826
 DI3826.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 DI3826.been affixed to the stable North American Tectonic Plate. 
 DI3826
 DI3826.The coordinates are valid at the epoch date displayed above
 DI3826.which is a decimal equivalence of Year/Month/Day.
 DI3826
 DI3826.NGS completed the third reprocessing of daily RINEX data from 1996 to 2022
 DI3826.for all stations in the NOAA CORS Network (NCN).  The reprocessed solution,
 DI3826.known as the Multi-Year CORS Solution 3 (MYCS3), is aligned with the
 DI3826.ITFR2020 global frame, epoch 2020.00.  The resulting MYCS3 coordinates
 DI3826.were then transformed to NAD83(2011/MA11/PA11), maintaining the currently
 DI3826.published epoch of 2010.00.

 DI3826.** This station is in an area of known vertical motion.  Due to the
 DI3826.** variability of land subsidence, uplift, and crustal motion, NGS has,
 DI3826.** determined the orthometric heights for marks in these suspect
 DI3826.** subsidence areas should be considered valid only at the epoch date
 DI3826.** associated with the orthometric height.  These heights must always
 DI3826.** be validated when used as control.  All previously superseded
 DI3826.** orthometric heights are now considered suspect and are available
 DI3826.** in the superseded section.  NGS does not recommend using suspect
 DI3826.** or superseded heights as control.
 DI3826
 DI3826.The orthometric height was determined by differential leveling and
 DI3826.adjusted by the NATIONAL GEODETIC SURVEY
 DI3826.in July 2012.

 DG3888.and adjusted by the National Geodetic Survey in June 2012.
 DG3888
 DG3888.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 DG3888.been affixed to the stable North American tectonic plate. See 
 DG3888.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 DG3888
 DG3888.The horizontal coordinates are valid at the epoch date displayed above
 DG3888.which is a decimal equivalence of Year/Month/Day.
 DG3888
 DG3888.The orthometric height was determined by differential leveling and
 DG3888.adjusted by the NATIONAL GEODETIC SURVEY
 DG3888.in March 2008.

 BT0945'THE ROAD, IN THE TOP OF A CONCRETE POST PROJECTING 6 IN., AND
 BT0945'STAMPED ARMSTRONG NO 2 1943.
 BT0945'
 BT0945'AZIMUTH MARK IS ABOUT 0.5 MI. SW OF THE STATION MARK, IN THE SE
 BT0945'EDGE OF A CULTIVATED FIELD, 31-1/2 FT. NW OF THE CENTERLINE OF THE
 BT0945'BLACK-TOP ROAD, 110 YARDS. NE OF THE CENTER OF A DRIVE SE TO A

 BT0945'
 BT0945'TO REACH THE STATION FROM TUMBLETON, PROCEED FOR ABOUT 0.95 MI. NE
 BT0945'ALONG A BLACK-TOP ROAD LEADING TO BROWN CROSSROAD FROM ITS JUNCTION

 BT0945'FOR ABOUT 0.5 MI. NE ALONG THE BLACK-TOP ROAD TO THE JUNCTION OF
 BT0945'A GRADED ROAD LEADING NW AND THE STATION MARK ON THE LEFT.
 BT0945'
 BT0945'BOTH REFERENCE MARK 1 AND THE AZIMUTH MARK WERE FOUND PUSHED OVER
 BT0945'BY ROAD EQUIPMENT OR FARMING OPERATIONS.  THEY WERE OF NO VALUE AS
 BT0945'THEY WERE, SO THEY WERE STRAIGHTENED UP BY OUR BENCH-MARK PARTY,
 BT0945'AND CONCRETE WAS ADDED TO THEIR BASES TO IMPROVE THEIR STABILITY.
 BT0945'THE AZIMUTH MARK APPEARED TO HAVE BEEN PUSHED OVER DIRECTLY ON
 BT0945'LINE WITH THE STATION AND WAS MOVED BACK IN THE OPPOSITE
 BT0945'DIRECTION.  IT SEEMS UNLIKELY THAT THIS DISTURBED ITS VALUE AS AN
 BT0945'AZIMUTH VERY MUCH, BUT THIS IS ONLY A GUESS.

 EF1419
 EF1419'DESCRIBED BY COAST AND GEODETIC SURVEY 1886
 EF1419'ON THE HIGHEST PART OF SAND MOUNTAIN AT THE HEAD OF BRISTOES COVE,
 EF1419'ABOUT 1 MILE EAST OF WHERE THE MAIN ROAD FROM GADSDEN TO
 EF1419'GUNTERSVILLE REACHES THE SUMMIT OF THE MOUNTAIN AND ABOUT 15 MILES
 EF1419'FROM ATTALLA, ALABAMA, ON THE ALABAMA GREAT SOUTHERN RAILROAD.
 EF1419'AURORA, WITH RURAL FREE DELIVERY FROM BOAZ, IS ABOUT 3 MILES
 EF1419'DISTANT.  THERE IS A SPRING ABOUT ONE-HALF MILE NORTHEAST OF THE
 EF1419'STATION.  THE SURFACE MARK IS A CROSS CUT ON A GRANITE POST 5 BY 5
 EF1419'INCHES SQUARE, BURIED WITH THE TOP COVERED WITH EARTH AND ROCK.  THE
 EF1419'LETTERS U.S.C.S. ARE ALSO CUT ON THE POST.  THE REFERENCE MARKS ARE
 EF1419'FOUR SIMILAR GRANITE POSTS WITH LINES CUT DIAGONALLY, THE
 EF1419'INTERSECTION OF WHICH IS 6 FEET FROM THE CENTER.  ARROWHEADS ARE
 EF1419'ALSO CUT ON ONE LINE OF EACH POST AND POINT TO THE CENTER AND
 EF1419'ARE DUE NORTH, SOUTH, EAST AND WEST OF THE STATION.  THE
 EF1419'UNDERGROUND MARK IS A GLASS BOTTLE FILLED WITH ASHES, BURIED NECK
 EF1419'DOWNWARD TO A DEPTH OF ABOUT 3 FEET.  IN 1886 THE EAST STONE WAS
 EF1419'FOUND LYING ON THE GROUND.  THE OTHER THREE STONES WERE FOUND IN
 EF1419'PLACE BUT THEIR TOPS HAD BEEN BROKEN OFF SO AS TO DESTROY ALL THE
 EF1419'DIAGONAL LINES AND LETTERS.  THE EAST STONE WAS RESTORED TO ITS
 EF1419'FORMER PLACE.

 EF1419
 EF1419'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1934 (MAH)
 EF1419'ON THE HIGHEST PART OF SAND MOUNTAIN, AT THE HEAD OF BRISTOES COVE,
 EF1419'ABOUT 4 MILES A LITTLE WEST OF SOUTH BOAZ, ALABAMA.  THE STATION WAS
 EF1419'A 5 BY 5 INCH SQUARE GRANITE POST SET OVER A GLASS BOTTLE FILLED WITH
 EF1419'ASHES.  THE REFERENCE MARKS WERE SIMILAR POSTS SET NORTH, EAST,
 EF1419'SOUTH AND WEST OF STATION AND 6 FEET DISTANT.  THE PROPERTY OWNER
 EF1419'REPORTS THAT IN 1932 TWO OF THE REFERENCE MARKS WERE PULLED OUT
 EF1419'AND USED AS GRAVE STONES.  IN 1933 THE OWNER WISHING TO BUILD A
 EF1419'CABIN, PULLED OUT THE STATION MARK AND REMAINING TWO REFERENCE MARKS
 EF1419'AND BUILT A LOG CABIN OVER THE STATION SITE.  IN 1934 C.W.A.
 EF1419'ENGINEERS DUG AND FOUND THE UNDERGROUND MARK, ALTHOUGH THE BOTTLE
 EF1419'WAS BROKEN IN DIGGING FOR IT, IT WAS LEFT IN PLACE AND THE
 EF1419'ORIGINAL STATION MARK-GRANITE POST WAS RESET OVER THE BOTTLE.
 EF1419'THIS POST IS NOW LOCATED UNDER THE REAR PORCH OF THE LOG CABIN.  A
 EF1419'NEW STATION WAS ESTABLISHED.  SEE DESCRIPTION ON AURORA ECC.

 EF0972'IT IS DIFFICULT TO KNOW THE ALIGNMENT OF THE ROAD HERE IN 1946, BUT IF
 EF0972'IT WAS THE SAME AS IT IS TODAY, THEN THE MARK IS UNDER FILL FROM
 EF0972'BUILDING THE ROAD, AS THE CURRENT ROAD IS SIGNIFICANTLY HIGHER THAN

 EE1101'OF THE MARK IS GONE AND THE ROAD HAS BEEN IMPROVED, SMOOTHING OUT THE

 EE1101'UPGRADED).  THE TELEPHONE POLE IS GONE AND IS THE DRIVEWAY.  ASSUMING
 EE1101'THE CULVERT IS THE SAME ONE FROM 1959 TO THE WEST OF THE MARK, THE
 EE1101'DRAINAGE ALONG THE ROAD HAS BEEN CHANGED.  THE MEASURED LOCATION OF
 EE1101'THE MARK IS WITHIN THE EXCAVATED AREA FOR THE ROADSIDE DRAIN AND AS IT
 EE1101'WAS PROJECTING WOULD BE EASILY REMOVED DURING THE ROAD RECONSTRUCTION
 EE1101'WORK, OR DURING DRAIN CONSTRUCTION.  THE MARK HAS PROBABLY BEEN
 EE1101'DESTROYED.  THE MEASURED AREA IS VERY CLOSE TO TREES ALONG THE NORTH
 EE1101'SIDE OF THE DRAIN AREA AND THIS LIMITS SKY VISIBILITY.  THE PHOTOS

 BH0073.** This station is in an area of known vertical motion.  Due to the
 BH0073.** variability of land subsidence, uplift, and crustal motion, NGS has,
 BH0073.** determined the orthometric heights for marks in these suspect
 BH0073.** subsidence areas should be considered valid only at the epoch date
 BH0073.** associated with the orthometric height.  These heights must always
 BH0073.** be validated when used as control.  All previously superseded

 BH0073.** or superseded heights as control.

 BU1019'THE ORIGINAL DESCRIPTION OF 1944 IS ADEQUATE EXCEPT FOR THE FOLLOWING
 BU1019'CHANGES AND ADDITIONS-
 BU1019'
 BU1019'THE ORIGINAL DESCRIPTION INCORRECTLY STATES THAT THE CEMETERY AND
 BU1019'THE STATION ARE TO THE LEFT WHEN TRAVELING FROM BELLEVILLE,
 BU1019'ALABAMA.  IT SHOULD HAVE BEEN RIGHT OR NORTH.  THE STATION IS LEFT
 BU1019'OR NORTH WHEN TRAVELING FROM BURNT CORN, ALABAMA AND IS IN THE
 BU1019'REAR OF A DWELLING HOUSE ON THE CREST OF A SLOPE IN A PINE
 BU1019'GROVE.  A METAL WITNESS POST AND SIGN ARE NEARBY AND THE STATION
 BU1019'IS 27 FEET SSW OF A TRIANGULAR BLAZED 12 INCH PINE TREE IN

 BU1019'RECOVERY NOTE BY TROY STATE UNIVERSITY 2023 (NWH)
 BU1019'THE MARK WAS NOT FOUND.  THE AREA AROUND THE JOHN GREEN CEMETERY FENCE
 BU1019'HAS BEEN CLEARED SOME YEARS AGO AND DIRT AND OTHER MATERIAL HAS BEEN
 BU1019'PUSHED OVER THE MEASURED LOCATION OF THE MARK TO A DEPTH OF 1 TO 2
 BU1019'FEET.  THE WITNESS POST WAS FOUND PUSHED OVER AND WITH THE PLATE GONE.
 BU1019'AS THIS MATERIAL HAS BEEN THERE FOR SOME TIME, TREES HAVE GROWN INTO
 BU1019'IT AND THE MARK MAY BE UNDER SIGNIFICANT QUANTITIES OF WOOD AND ROOTS,
 BU1019'NEEDING A MORE VIGOROUS APPROACH TO CLEARING.  A NUMBER OF ROCKS WERE
 BU1019'ENCOUNTERED WHILE SEARCHING FOR THE MARK AND THESE MAY HAVE BEEN
 BU1019'PUSHED ABOVE IT, MAKING RECOVERY DIFFICULT.  THE MEASURED LOCATION IS

 BV0197.** subsidence areas should be considered valid only at the epoch date
 BV0197.** associated with the orthometric height.  These heights must always
 BV0197.** be validated when used as control.  All previously superseded

 BH0008.** This station is in an area of known vertical motion.  Due to the
 BH0008.** variability of land subsidence, uplift, and crustal motion, NGS has,
 BH0008.** determined the orthometric heights for marks in these suspect
 BH0008.** subsidence areas should be considered valid only at the epoch date
 BH0008.** associated with the orthometric height.  These heights must always
 BH0008.** be validated when used as control.  All previously superseded

 BH0008.** in the superseded section.  NGS does not recommend using suspect
 BH0008.** or superseded heights as control.

 EF0974'RECOVERY NOTE BY TROY STATE UNIVERSITY 2022 (NWH)
 EF0974'THE MARK WAS NOT FOUND AT THE MEASURED LOCATION, BASED ON THE CURRENT
 EF0974'ROADS.  HOWEVER, POSSIBLE THAT THE ROAD WAS ABOUT 40 FT (12.2 M) WEST
 EF0974'OF THE CURRENT LOCATION IN 1946, BASED ON THE DISTANCE FROM AN OLD
 EF0974'WOODEN HOUSE, NOW PAINTED WHITE BUT APPARENTLY UNOCCUPIED.  IN THAT
 EF0974'CASE, THE MARK WOULD BE IN THE DRAIN THAT WAS DUG DEEPER IN THAT
 EF0974'GENERAL AREA TO INSTALL A CULVERT UNDER THE MAIN ROAD ON THE NORTH
 EF0974'EDGE OF THE INTERSECTION.  THE MARK IS PROBABLY GONE IN EITHER CASE.

 DH0911'RECOVERY NOTE BY GEOCACHING 2003 (JAJ)
 DH0911'ALTHOUGH THE MARK MAY STILL BE IN THE LOCATION IN WHICH IT WAS
 DH0911'MOMUMENTED, THE MARK COULD NOT BE FOUND AFTER AN INTENSIVE SEARCH.
 DH0911'MOST LIKELY THE MARK IS EITHER DESTROYED OR BURIED DEEP UNDER ALMOST
 DH0911'60 YEARS WORTH OF TREES AND LEAVES WHICH HAVE FALLEN IN THE AREA. THE
 DH0911'DOUBLE 16-INCH CULVERT MENTIONED IN THE ORIGINAL DESCRIPTION WAS
 DH0911'LOCATED, BUT NOT THE ACTUAL MARK.

 EE1233'THE MARK WAS NOT FOUND.  MOST OF THE THINGS CITED IN THE 1947
 EE1233'DESCRIPTION ARE GONE.  THE GRAVEL STREET IS NOW SEALED.  THE REMAINS
 EE1233'OF THE CONCRETE SIDEWALK ARE STILL THERE, BUT A CHAIN LINK FENCE IS
 EE1233'NOW ALONG THE SOUTHWEST EDGE OF THE SIDEWALK.  THE MARK APPEARS TO BE
 EE1233'INSIDE THE NORTH CORNER OF A FENCED YARD AROUND A TRUCK DEPOT.  THIS
 EE1233'AREA HAS HAD DIRT AND GRAVEL DUMPED TO MAKE A FIRM BASE FOR PARKING
 EE1233'TRAILERS, SO THE MARK IS PROBABLY BURIED, IF IT IS STILL THERE.
 EE1233'NOTING THAT THE MARK WAS FOUND IN POOR CONDITION IN 1964, IT MAY WELL

 DG3595'STATION IS ON THE HIGHEST PART OF THE MOUNTAINS AMONG ROCKY
 DG3595'OUTCROPPINGS, ABOUT 9 MILES S OF OXFORD.  THERE IS A PRECIPITOUS
 DG3595'BLUFF ON THE WESTERN SIDE OF THE MOUNTAIN KNOWN AS THE PULPIT.
 DG3595'THE STATION IS ON A TURNING POINT OF THE BOUNDARY LINE BETWEEN
 DG3595'TALLADEGA AND CLAY COUNTIES.
 DG3595'
 DG3595'THE STATION WAS MARKED BY A CROSS CUT ON A STONE BURIED ABOUT
 DG3595'1 FOOT BELOW THE SURFACE IN A CLEFT BETWEEN THE LEDGES.  ANOTHER
 DG3595'STONE WITH A CROSS CUT ON TOP WAS SET OVER THIS AND PROJECTS 1
 DG3595'FOOT ABOVE THE SURFACE.  TO THE EASTWARD AND SOUTHWARD SHALLOW
 DG3595'HOLES WERE DRILLED INTO THE CENTERS OF TRIANGLES CUT INTO
 DG3595'OUTCROPPING ROCKS.  THE S MARK BEARS S 30-1/2 DEG. W AND IS
 DG3595'DISTANT FROM THE CENTER OF THE STATION 4.17 FEET (1.27 METERS).

 DG3595'THE OLD STATION COULD NOT BE RECOVERED BECAUSE A LOOKOUT TOWER
 DG3595'HAS BEEN BUILT OVER THE SITE OF THE STATION.  THE ENGINEER IN
 DG3595'CHARGE OF CONSTRUCTING THE LOOKOUT TOWER WAS CONTACTED AND HE SAID
 DG3595'THAT HE RECOVERED THE OLD SURFACE AND UNDERGROUND MARKS (CROSSES
 DG3595'CUT IN ROCKS) AT THE TIME THE TOWER WAS BUILT AND THAT HE PLUMBED
 DG3595'IN A POINT OVER THE OLD UNDERGROUND MARK AND MARKED IT IN THE
 DG3595'CONCRETE FLOOR OF THE TOWER BY A CROSS.  THE POSITION OF THIS
 DG3595'CROSS WAS COMPUTED AND IT IS BELIEVED THAT IT IS DIRECTLY OVER
 DG3595'THE OLD STATION.
 DG3595'
 DG3595'THE STATION IS NOW MARKED BY A CROSS IN THE CENTER OF THE
 DG3595'CONCRETE FLOOR OF THE LOOKOUT TOWER AT THE GROUND LEVEL.  THE
 DG3595'LOOKOUT TOWER IS OF STONE AND CONCRETE CONSTRUCTION ABOUT 50
 DG3595'FEET HIGH AND HAS A GLASSED-IN OBSERVATION ROOM AT THE TOP.  IT IS
 DG3595'LOCATED ON THE HIGHEST PART OF CHEAHA MOUNTAIN (THE HIGHEST POINT
 DG3595'IN ALABAMA) IN CHEAHA STATE PARK AND IS ABOUT 9 MILES S OF
 DG3595'OXFORD.

 CN3113.This mark is at Gragg-Wade Field Airport (02A)
 CN3113
 CN3113.The horizontal coordinates were established by GPS observations
 CN3113.and adjusted by the National Geodetic Survey in June 2012.
 CN3113
 CN3113.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 CN3113.been affixed to the stable North American tectonic plate. See 
 CN3113.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 CN3113
 CN3113.The horizontal coordinates are valid at the epoch date displayed above
 CN3113.which is a decimal equivalence of Year/Month/Day.
 CN3113
 CN3113.The orthometric height was determined by differential leveling and
 CN3113.adjusted by the NATIONAL GEODETIC SURVEY
 CN3113.in May 2024.
 CN3113
 CN3113.Significant digits in the geoid height do not necessarily reflect accuracy.

 CN3113
 CN3113.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 CN3113
 CN3113.The Laplace correction was computed from DEFLEC18 derived deflections.
 CN3113
 CN3113.The ellipsoidal height was determined by GPS observations
 CN3113.and is referenced to NAD 83.
 CN3113
 CN3113.The dynamic height is computed by dividing the NAVD 88
 CN3113.geopotential number by the normal gravity value computed on the
 CN3113.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 CN3113.degrees latitude (g = 980.6199 gals.).
 CN3113
 CN3113.The modeled gravity was interpolated from observed gravity values.

 BG4118
 BG4118'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1940 (HWG)
 BG4118'DUE TO THE CONSTRUCTION OF A HOTEL AT THIS LOCATION IT BECAME
 BG4118'NECESSARY TO LOWER THIS STATION ABOUT TWO FEET IN ORDER TO BRING IT
 BG4118'DOWN TO THEIR GRADE SO IT WOULD NOT BE AN OBSTRUCTION.  THE STATION
 BG4118'WAS THEREFORE LOWERED TO THEIR GRADE SURFACE, AND ITS IDENTICAL
 BG4118'POSITION WAS MAINTAINED.
 BG4118'
 BG4118'THE REFERENCE MARKERS WERE BURIED UNDER DRIFTING SAND DUNES AND ONLY
 BG4118'ONE WAS RECOVERED AND CHECKED.  THE REFERENCE MARKS WILL BE BURIED
 BG4118'BY THEIR GRADING OPERATIONS.  THE ONLY POSSIBLE REFERENCES REMAINING

 BH0275.** This station is in an area of known vertical motion.  Due to the
 BH0275.** variability of land subsidence, uplift, and crustal motion, NGS has,
 BH0275.** determined the orthometric heights for marks in these suspect

 BH0275.** associated with the orthometric height.  These heights must always
 BH0275.** be validated when used as control.  All previously superseded
 BH0275.** orthometric heights are now considered suspect and are available
 BH0275.** in the superseded section.  NGS does not recommend using suspect
 BH0275.** or superseded heights as control.
 BH0275
 BH0275.The orthometric height was determined by differential leveling and
 BH0275.adjusted by the NATIONAL GEODETIC SURVEY
 BH0275.in July 2012.

 BH0064.** This station is in an area of known vertical motion.  Due to the
 BH0064.** variability of land subsidence, uplift, and crustal motion, NGS has,
 BH0064.** determined the orthometric heights for marks in these suspect
 BH0064.** subsidence areas should be considered valid only at the epoch date
 BH0064.** associated with the orthometric height.  These heights must always
 BH0064.** be validated when used as control.  All previously superseded
 BH0064.** orthometric heights are now considered suspect and are available
 BH0064.** in the superseded section.  NGS does not recommend using suspect
 BH0064.** or superseded heights as control.
 BH0064
 BH0064.The orthometric height was determined by differential leveling and
 BH0064.adjusted by the NATIONAL GEODETIC SURVEY
 BH0064.in July 2012.

 BH0064
 BH0064.The Laplace correction was computed from DEFLEC18 derived deflections.
 BH0064
 BH0064.The dynamic height is computed by dividing the NAVD 88
 BH0064.geopotential number by the normal gravity value computed on the
 BH0064.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 BH0064.degrees latitude (g = 980.6199 gals.).
 BH0064
 BH0064.The modeled gravity was interpolated from observed gravity values.

 DM5373.NGS completed the third reprocessing of daily RINEX data from 1996 to 2022
 DM5373.for all stations in the NOAA CORS Network (NCN).  The reprocessed solution,
 DM5373.known as the Multi-Year CORS Solution 3 (MYCS3), is aligned with the
 DM5373.ITFR2020 global frame, epoch 2020.00.  The resulting MYCS3 coordinates

 AA9093.The horizontal coordinates were established by GPS observations
 AA9093.and adjusted by the National Geodetic Survey in June 2012.
 AA9093
 AA9093.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 AA9093.been affixed to the stable North American tectonic plate. See 
 AA9093.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 AA9093
 AA9093.The horizontal coordinates are valid at the epoch date displayed above
 AA9093.which is a decimal equivalence of Year/Month/Day.
 AA9093
 AA9093.The orthometric height was determined by differential leveling
 AA9093.and adjusted by the NATIONAL GEODETIC SURVEY in February 1996.
 AA9093
 AA9093.The height was determined by precise leveling from only one NSRS
 AA9093.bench mark.  This was not adequate 'tie leveling' to NSRS and was
 AA9093.allowed ONLY to validate the GPS-derived height.

 AA9093.The Laplace correction was computed from DEFLEC18 derived deflections.
 AA9093
 AA9093.The ellipsoidal height was determined by GPS observations
 AA9093.and is referenced to NAD 83.
 AA9093
 AA9093.The dynamic height is computed by dividing the NAVD 88
 AA9093.geopotential number by the normal gravity value computed on the
 AA9093.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 AA9093.degrees latitude (g = 980.6199 gals.).

 DM3965.NGS completed the third reprocessing of daily RINEX data from 1996 to 2022
 DM3965.for all stations in the NOAA CORS Network (NCN).  The reprocessed solution,
 DM3965.known as the Multi-Year CORS Solution 3 (MYCS3), is aligned with the
 DM3965.ITFR2020 global frame, epoch 2020.00.  The resulting MYCS3 coordinates
 DM3965.were then transformed to NAD83(2011/MA11/PA11), maintaining the currently
 DM3965.published epoch of 2010.00.

 BU0409'THE MARK WAS NOT FOUND.  THE PURE OIL SERVICE STATION IS NOW A HOME,
 BU0409'BUT THE CONCRETE ISLAND FOR THE PUMPS IS STILL THERE.  THE DRIVEWAY IS
 BU0409'APPARENTLY STILL THERE, BUT EVERYTHING SEEMS TO BE A BIT TO THE SOUTH
 BU0409'OF THE EARLIER DESCRIPTION, I.E., THE FENCE AND THE GATE, OR THE ROAD
 BU0409'HAS BEEN MOVED A LITTLE TO THE NORTH.  THERE IS NO CERTAINTY THAT THE
 BU0409'ROAD IS IN THE SAME PLACE AS IN 1955.  THE BUNGALOW IS GONE OR IS SO
 BU0409'BURIED IN VEGETATION AS TO BE INVISIBLE.  THE ROADSIDE DRAIN HAS BEEN
 BU0409'COMPLETELY CHANGED AND THERE IS NO LONGER A PIPE UNDER THE DRIVEWAY.
 BU0409'THE MEASURED LOCATION, BASED ON THE ROAD CENTERLINE AND AN ESTIMATE OF
 BU0409'THE PIPE LOCATION, PLACES THE MARK CLOSE TO TREES.
