Documented History (by the NGS)
|01/01/1934 by CGS (MONUMENTED)
|DESCRIBED BY COAST AND GEODETIC SURVEY 1934
12.3 MI W FROM CAMERON. ABOUT 12.3 MILES WEST ALONG STATE HIGHWAY 64 FROM CAMERON, COCONINO COUNTY, ABOUT 75 FEET EAST OF A 2-FOOT GALVANIZED-IRON CULVERT, 71 FEET NORTHEAST OF THE CENTER LINE OF THE HIGHWAY, IN THE TOP OF A SANDSTONE BOULDER, AND ABOUT 1 FOOT ABOVE GROUND. A STANDARD DISK, STAMPED R 62 1934.

|RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1977 (TT)
THE STATION IS ABOUT 50 MILES EAST NORTHEAST OF FLAGSTAFF, 10 MILES WEST NORTHWEST OF CAMERON, ON THE NORTHEAST SIDE OF ARIZONA HWY. 64.
THE STATION IS AN USC AND GS BENCH MARK STAMPED R 62 1934 AND IS SET IN A DRILL HOLE IN TOP OF A LARGE SANDSTONE BOULDER WHICH PROJECTS 1 FOOT. THE STATION IS 71 FEET NORTHEAST OF HWY. 64 CENTERLINE AND IS MARKED BY A WITNESS POST AND SIGN 3 FEET TO SOUTH.
REFERENCE MARK 1 IS AN AZDT HWY. DIVISION DISK STAMPED SIDE RM 1 1977 AND IS EPOXIED TO BEDROCK 102 FEET NORTHEAST OF HWY. CENTERLINE.
REFERENCE MARK 2 IS AN AZDT HWY. DIVISION DISK STAMPED SIDE RM 2 1977 EPOXIED TO A ROCK 97 FEET NORTHEAST OF HWY. CENTERLINE.
TO REACH THE STATION FROM CAMERON, TRAVEL SOUTH ON U.S. HWY. 89 TO THE JUNCTION WITH STATE HWY. 64, TURN RIGHT, WEST, AND CONTINUE ON HWY. 64 TO MILE POST 285.66 AND THE STATION ON NORTH SIDE OF HWY.

RECOVERED IN GOOD CONDITION.
- The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in August 1993.
- The orthometric height was determined by differential leveling and adjusted by the National Geodetic Survey in 1992. * This is a POSTED BENCH MARK height. Code A indicates a distribution rate of 0.0 thru 1.0 mm/km.
- The Laplace correction was computed from DEFLEC99 derived deflections.
- The geoid height was determined by GEOID99.
- 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.
