I recovered this U.S. Coast & Geodetic Survey triangulation station from 1931 in good condition. It is monumented on a large boulder near a weather station. The NGS datasheet log from 1948 is adequate for station recovery.
NGS datasheet info:
01/01/1948 by CGS (MONUMENTED)
THE STATION IS ABOUT 30 MILES NORTH NORTHWEST OF ALTURAS, ON THE WEST EDGE OF A SMALL TIMBERED HILL KNOWN AS BLUE MOUNTAIN.
REFERENCE MARK NUMBER 2, STAMPED BLUE NO 2 1931, IS SET IN BEDROCK, NOTE 12A, IS SET IN A BEDROCK OUTCROP, PROJECTS 3 FEET AND IS 18 INCHES HIGHER THAN THE STATION. IT IS 13 FEET WEST OF THE SOUTHWEST CORNER OF WHITE FENCE.
TO REACH THE STATION FROM THE U.S. POST OFFICE IN ALTURAS, GO NORTH ON U.S. HIGHWAY 395 FOR 0.8 MILE. TURN LEFT, WEST, ON U.S. HIGHWAY 299 AND GO 3.5 MILES. TAKE RIGHT FORK, GRAVEL ROAD, AS PER SIGN CROWDER FLAT 33 AND GO 1.9 MILES. TAKE RIGHT FORK AND GO 7.2 MILES. TAKE RIGHT FORK AND GO 0.8 MILE. TAKE RIGHT FORK AND GO 3.7 MILES. TAKE LEFT FORK AND GO 1.9 MILES. TAKE LEFT FORK AND GO 13.0 MILES. TAKE LEFT FORK AS PER SIGN BLUE MTN. LOOKOUT AND GO 5.6 MILES. TURN LEFT 100 YARDS. TAKE RIGHT FORK AND GO 1.3 MILES TO THE LOOKOUT TOWER AND STATION. NOTE-- THE AZIMUTH FROM THE STATION TO R.M. 2 WAS 244 39 IN THE 1931 DESCRIPTION BUT WAS CHECKED IN THE FIELD AND FOUND TO BE 344 39.
