Yorkville E GPS Control Station Disk - U.S. Benchmarks on Waymarking.com

Saw the Witness Posts for this benchmark while driving on Hwy 11 late yesterday. Went back to investigate today. Found the Benchmark inside the 3 Witness Posts.

DF9483.The horizontal coordinates were established by GPS observations
DF9483.and adjusted by the National Geodetic Survey in February 2007.
DF9483
DF9483.The datum tag of NAD 83(2007) is equivalent to NAD 83(NSRS2007).
DF9483.See www.ngs.noaa.gov/NationalReadjustment for more information.
DF9483.The horizontal coordinates are valid at the epoch date displayed above.
DF9483.The epoch date for horizontal control is a decimal equivalence
DF9483.of Year/Month/Day.
DF9483
DF9483.The orthometric height was determined by differential leveling
DF9483.and adjusted in April 2007.
DF9483
DF9483.The X, Y, and Z were computed from the position and the ellipsoidal ht.
DF9483
DF9483.The Laplace correction was computed from DEFLEC99 derived deflections.
DF9483
DF9483.The ellipsoidal height was determined by GPS observations
DF9483.and is referenced to NAD 83.
DF9483
DF9483.The geoid height was determined by GEOID03.
DF9483
DF9483.The dynamic height is computed by dividing the NAVD 88
DF9483.geopotential number by the normal gravity value computed on the
DF9483.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
DF9483.degrees latitude (g = 980.6199 gals.).
DF9483
DF9483.The modeled gravity was interpolated from observed gravity values.
