DESCRIBED BY US GEOLOGICAL SURVEY 1967 24.9 MI NE FROM KINGMAN. TO REACH FROM THE ATCHISON TOPEKA AND SANTA FE RAILROAD DEPOT IN KINGMAN, ARIZONA GO EAST ON US HIGHWAY 66 FOR 21.5 MILES TO PIERCE FERRY ROAD AT ANTARES. TURN LEFT, (NORTH) ON PIERCE FERRY ROAD AND GO 3.4 MILES. BENCH MARK IS 75 FT EAST OF ROAD AND 20 FT EAST OF A NORTH-SOUTH FENCE. A STANDARD DISK SET IN CONCRETE POST PROJECTING 0.8 FT.

Control Text

  • The horizontal coordinates were scaled from a topographic map and have an estimated accuracy of +/- 6 seconds.
  • 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 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.
