AH9497 - NGS 'EUGENE CBL 0' Calibration Baseline Disk - Eugene, OR - U.S. Benchmarks on Waymarking.com

I recovered this National Geodetic Survey Calibration Baseline Station from 1993 in good condition. It is a brass disk monumented in a round concrete monument flush with the ground and surrounded by three white wooden witness posts. My posted coordinates will place you very close to this station.
