 DX4944.The horizontal coordinates were established by classical geodetic methods
 DX4944.and adjusted by the National Geodetic Survey in June 1996.
 DX4944.The horizontal coordinates are valid at the epoch date displayed above.
 DX4944.The epoch date for horizontal control is a decimal equivalence
 DX4944.of Year/Month/Day.
 DX4944
 DX4944.The NAVD 88 height was computed by applying the VERTCON shift value to
 DX4944.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
 DX4944
 DX4944.The Laplace correction was computed from DEFLEC99 derived deflections.
 DX4944
 DX4944.The geoid height was determined by GEOID99.

 DX4944'DESCRIBED BY US ENGINEERS 1940
 DX4944'STATION IS A STANDARD DISK CEMENTED IN A HUGE ROCK.
 DX4944'
 DX4944'IT IS LOCATED ABOUT 3.5 MILES EAST OF RANCHITA POST OFFICE IN
 DX4944'MONTEZUMA VALLEY, ON HIGH VERY PROMINENT, ROCKY POINT.  TO REACH
 DX4944'FROM RANCHITA POST OFFICE TAKE DIRT ROAD EAST 0.8 MILE TO A CATTLE
 DX4944'GUARD, CONTINUE STRAIGHT AHEAD 0.4 MILE TO FORK, TAKE RIGHT FORK
 DX4944'AND FOLLOW MAIN TRAVELED ROAD 0.75 MILE TO OLD SHACK.  TURN LEFT
 DX4944'THROUGH FIELD 0.3 MILE.  LEAVE TRUCK AND CLIMB TO TOP OF
 DX4944'NEAREST HILL.  FROM THIS POINT A HIGH, ROCKY POINT CAN BE SEEN
