THE STATION IS A US GEOLOGICAL SURVEY BENCH MARK DISK SET AT THE HIGHEST POINT OF THE GRANITE BEDROCK, ABOUT 150 FT (45.7 M) SOUTH-SOUTHWEST OF AND ABOUT 21 FT (6.4 M) HIGHER THAN BENCH MARK UU 836, 53 FT (16.2 M) NORTH-NORTHEAST OF A METAL SIGN POST SET IN CONCRETE (NO SIGN ATTACHED) , 23.5 FT (7.2 M) EAST OF THE CENTER OF THE WEATHER STATION FOUNDATION, 22 FT (6.7 M) SOUTH OF A PINE TREE GROWING IN A CREVICE IN THE GRANITE, 6 FT (1.8 M) WEST OF THE EAST EDGE OF THE GRANITE BEDROCK AND ABOUT 4 FT (1.2 M) HIGHER THAN THE FOUNDATION. THE STATION WAS OCCUPIED AS PART OF THE STATE OF NEVADA HIGH ACCURACY REFERENCE NETWORK (HARN) SURVEY. <p> <h2>STATION RECOVERY (1996) </h2> <p>RECOVERY NOTE BY CALTRANS 1996 (PTD) RECOVERED AS DESCRIBED.
