 PC0853.The horizontal coordinates were established by classical geodetic methods
 PC0853.and adjusted by the National Geodetic Survey in October 1991.
 PC0853
 PC0853.The NAVD 88 height was computed by applying the VERTCON shift value to
 PC0853.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
 PC0853.The vertical order pertains to the NGVD 29 superseded value.
 PC0853
 PC0853.The Laplace correction was computed from DEFLEC09 derived deflections.
 PC0853
 PC0853.The geoid height was determined by GEOID09.

 PC0853'THE STATION IS LOCATED ABOUT 7 MILES NORTHEAST OF THE QUARTZ GUARD
 PC0853'STATION, ON THE HIGHEST POINT OF TWIN LAKES MTN., WHICH IS
 PC0853'OCCUPIED BY A U.S. FOREST SERVICE LOOKOUT TOWER.
 PC0853'
