 DX4972.The horizontal coordinates were established by classical geodetic methods
 DX4972.and adjusted by the National Geodetic Survey in June 1996.
 DX4972.The horizontal coordinates are valid at the epoch date displayed above.
 DX4972.The epoch date for horizontal control is a decimal equivalence
 DX4972.of Year/Month/Day.
 DX4972
 DX4972.The NAVD 88 height was computed by applying the VERTCON shift value to
 DX4972.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
 DX4972
 DX4972.The Laplace correction was computed from DEFLEC99 derived deflections.
 DX4972
 DX4972.The geoid height was determined by GEOID99.

 DX4972'DESCRIBED BY US ENGINEERS 1941
 DX4972'STATION IS A SPIKE DRIVEN IN ROCK IN A GROUP OF ROCKS ON HIGHEST
 DX4972'POINT OF HILL.
 DX4972'
 DX4972'IT IS LOCATED ABOUT 7 MILES (AIRLINE) EAST-NORTHEAST OF WARNER
 DX4972'SPRINGS ON TOP OF A BRUSHY HILL ON THE NORTH SIDE OF A DRY WASH THAT
 DX4972'BECOMES A CANYON WINDING IN AN EASTERLY DIRECTION TO JOIN PALM
 DX4972'CANYON NEAR THE BORREGO DESERT.
