The horizontal coordinates were established by GPS observations and adjusted by the National Geodetic Survey in March 1998.

The orthometric height was determined by differential leveling and adjusted by the National Geodetic Survey in June 1991.

The X, Y, and Z were computed from the position and the ellipsoidal ht.

The Laplace correction was computed from DEFLEC96 derived deflections.

The ellipsoidal height was determined by GPS observations and is referenced to NAD 83.

The geoid height was determined by GEOID96.

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

The modeled gravity was interpolated from observed gravity values.

Station Recovery (1997)

RECOVERY NOTE BY NATIONAL GEODETIC SURVEY 1997 (CWS) THE STATION DESCRIPTION IS GOOD. A NEW TO REACH IS GIVEN AT THIS TIME TO HELP GET TO THE STATION FROM FORT COLLINS. IT IS IN THE NORTHWEST 1/4 OF SECTION 33, T 11 N, R 76 W. OWNERSHIP--LARIMER COUNTY ROAD RIGHT-OF-WAY TO REACH THE STATION FROM THE INTERSECTION OF U. S. HIGHWAY 287 AND COLORADO HIGHWAY 14, GO WEST ON COLORADO HIGHWAY 14 FOR 52.0 MI (83.7 KM) TO A SIDE ROAD RIGHT, (AT MILE POST 71.5) LARIMER COUNTY ROAD 103 (LARAMIE RIVER ROAD) . TURN RIGHT, NORTH, ON LARIMER COUNTY ROAD 103 FOR 15.8 MI (25.4 KM) TO THE INTERSECTION OF LARIMER COUNTY ROAD 190. CONTINUE AHEAD, RIGHT, ON LARIMER COUNTY ROAD 103 FOR 5.9 MI (9.5 KM) TO THE INTERSECTION OF LARIMER COUNTY ROAD 80 C. CONTINUE AHEAD, NORTHWESTERLY, ON LARIMER COUNTY ROAD 103 FOR 1.5 MI (2.4 KM) TO THE STATION ON THE LEFT. THE MARK IS A STANDARD DISK SET IN A .3 M (1.0 FT) DIAMETER CONCRETE POST, 0.15 M (0.49 FT) ABOVE GROUND. IT IS 17.5 M (57.4 FT) WEST OF THE CENTERLINE OF LARIMER COUNTY ROAD 103, 2.3 M (7.5 FT) EAST OF THE FENCE, 1.5 M (4.9 FT) SOUTH OF A FIBERGLASS WITNESS POST.
