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

The orthometric height was determined by GPS observations.

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.

STATION DESCRIPTION

DESCRIBED BY COAST AND GEODETIC SURVEY 1949 (DHK) THE STATION IS LOCATED ON THE SOUTH EDGE OF A LOW, BARE POINT OF RIDGE WHICH EXTENDS TO THE EAST FROM A HIGHER, TIMBERED RIDGE. ABOUT 2.5 MILES AIR LINE SOUTHEAST OF THE MOUNTAIN HOME SERVICE STATION. ABOUT 1.0 MILE AIR LINE SOUTH OF THE WYOMING-COLORADO STATE LINE AND 4 FEET NORTH OF A WHITE WITNESS POST WEDGED IN A LARGE ROCK OUTCROP. THE STATION MARK IS DEPRESSED 10 INCHES AND STAMPED, ROACH 1949. REFERENCE MARK NO. 1 IS APPROXIMATELY 3 FEET LOWER THAN THE STATION MARK, PROJECTS 6 INCHES AND STAMPED, ROACH NO 1 1949. REFERENCE MARK NO. 2 IS APPROXIMATELY 18 INCHES LOWER THAN THE STATION MARK, PROJECTS 18 INCHES AND STAMPED, ROACH NO 2 1949. REFERENCE MARK IS A U.S. DEPARTMENT OF AGRICULTURE, FOREST SERVICE BRONZE DISK SET IN A 10 X 10 INCH CONCRETE POST APPROXIMATELY 6 INCHES LOWER THAN THE STATION MARK. IT PROJECTS 4 INCHES AND IS STAMPED, RAS P 36 1937. THE AZIMUTH MARK IS 50 FEET EAST OF THE EDGE OF TIMBER, 30 FEET NORTH OF THE CENTER LINE OF ROAD AND 2 FEET SOUTH OF A WHITE WITNESS POST. IT PROJECTS 4 INCHES AND IS STAMPED, ROACH 1949. TO REACH FROM THE POST OFFICE IN LARAMIE, GO NORTH ONE BLOCK. TURN LEFT, WEST, AND FOLLOW STATE HIGHWAY 230 AND 130 FOR 2.0 MILES TO JUNCTION. TAKE LEFT FORK, STATE HIGHWAY 230, FOR 38.6 MILES TO THE MOUNTAIN HOME SERVICE STATION ON THE RIGHT. CONTINUE ON HIGHWAY 0.1 MILE TO A SIDE ROAD LEFT AND SIGN OX YOKE RANCH. TURN LEFT, SOUTH, FOR 0.3 MILE TO FORK JUST AFTER CROSSING RAILROAD TRACK. TURN LEFT, EAST, FOR 2.9 MILES TO FORK AND SIGN, OLD ROACH 10. TAKE RIGHT FORK, PASSING THROUGH POLE GATE, AND GO 0.3 MILE TO POLE GATE. PASS THROUGH GATE AND GO 0.8 MILE (TO REACH AZIMUTH MARK FROM THIS POINT, CONTINUE ON ROAD FOR 0.2 MILE TO MARK ON THE RIGHT).
