 HR2847.The horizontal coordinates were established by classical geodetic methods
 HR2847.and adjusted by the National Geodetic Survey in March 1994.
 HR2847.The horizontal coordinates are valid at the epoch date displayed above.
 HR2847.The epoch date for horizontal control is a decimal equivalence
 HR2847.of Year/Month/Day.
 HR2847
 HR2847.The NAVD 88 height was computed by applying the VERTCON shift value to
 HR2847.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
 HR2847
 HR2847.The Laplace correction was computed from DEFLEC99 derived deflections.
 HR2847
 HR2847.The geoid height was determined by GEOID99.

 HR2847'NORTH ON WELL MARKED TRAIL FOR ABOUT 1-1/2 MILES TO MAY
 HR2847'LAKE.  THEN PACK WEST ACROSS THE SOUTH END OF THE LAKE
 HR2847'PASSING TO THE LEFT OF A WOODEN WATER TANK.  HERE TAKE THE
 HR2847'MT. HOFFMANN TRAIL AND PACK SOUTHWEST THRU A CANYON AND
 HR2847'TO THE SOUTHWEST END OF A SMALL MEADOW.  THEN FOLLOW THE
 HR2847'TRAIL, WHICH IS WELL MARKED BY DUCKS, WEST-NORTHWEST TO THE
 HR2847'HIGHEST PART OF MT.  HOFFMANN AND THE STATION AND
 HR2847'REFERENCE MARKS AS DESCRIBED.
 HR2847'
 HR2847'LENGTH OF PACK ABOUT THREE HOURS.
 HR2847'
 HR2847'TO REACH THE AZIMUTH MARK FROM THE STATION PACK EAST FOR ABOUT
 HR2847'0.35 MILE TO THE HIGH PART OF A PROMINENT ROCK RIDGE AND THE
 HR2847'AZIMUTH MARK.
