I recovered this U.S. Coast & Geodetic Survey triangulation station (acting as an Azimuth Mark for BLUE 1931 PID #MW0818) from 1948 in good condition. It is monumented on some large bedrock east of nearby Lookout Tree (PID #MW0821) and amidst a deteriorating wooden survey stand/tower. The NGS datasheet is adequate for station recovery.
NGS datasheet info:
01/01/1948 by CGS (MONUMENTED)
DESCRIBED BY COAST AND GEODETIC SURVEY 1948 (WRH) THE STATION IS ON THE EAST EDGE OF BLUE MOUNTAIN, 30 MILES NORTH NORTHWEST OF ALTURAS. IT IS ON A LARGE ROCK OUTCROPPING 70 FEET SOUTHEAST OF A TREE TOP LOOKOUT. THE STATION MARK, STAMPED BLUE AZ 1948, IS SET IN A LARGE BOULDER PROJECTING ABOUT 2 FEET.
STATION BLUE 1931 WILL SERVE AS THE AZIMUTH MARK.
TO REACH THE STATION FROM THE U.S. POST OFFICE IN ALTURAS, GO 0.8 MILE NORTH ON MAIN STREET. TURN LEFT ON U.S. HIGHWAY 299 AND GO 3.5 MILES. TURN RIGHT ON THE BLUE MTN. ROAD AND GO 2.0 MILES. TURN RIGHT AND CONTINUE FOR 7.0 MILES. TURN RIGHT AND GO 0.8 MILE. TURN RIGHT AND GO 3.7 MILES. TURN LEFT AND GO 1.9 MILES. TURN LEFT AND GO 13.0 MILES. TURN LEFT AS PER SIGN BLUE MTN. LOOKOUT AND GO 5.6 MILES. TURN LEFT FOR 100 YARDS, TAKE RIGHT FORK AND GO 1.25 MILES. TURN LEFT ON DIM ROAD AND GO 0.55 MILE TO STATION ON THE RIGHT.
