GS0827.The horizontal coordinates are valid at the epoch date displayed above. GS0827.The epoch date for horizontal control is a decimal equivalence GS0827.of Year/Month/Day. GS0827 GS0827.The NAVD 88 height was computed by applying the VERTCON shift value to GS0827.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)

IT IS GS0827'LOCATED ABOUT 20 MILES NORTH NORTHEAST OF DARWIN, ABOUT 20 GS0827'MILES EAST NORTHEAST OF KEELER AND ABOUT 1 MILE NORTH OF GS0827'JACKASS SPRING ON A HIGH POINT OF THE MOUNTAIN THAT IS LOCALLY GS0827'KNOWN AS HUNTER MOUNTAIN. THE DISK IS SET IN A DRILL HOLE GS0827'IN THE TOP OF A LARGE BOULDER WHICH TOPS THE PEAK. IT IS GS0827'STAMPED JACKASS 1948. THE OBSERVATIONS WERE ON A TARGET GS0827'PLACED OVER THE MARK.
