NY0913 - USC&GS 'UNDERPASS' Series - Klamath County, OR - U.S. Benchmarks on Waymarking.com

I recovered three of four U.S. Coast & Geodetic Survey benchmarks from the UNDERPASS series from 1948 in good condition. Reference Mark 1 was recovered flush with the ground and easily covered with debris. Reference Mark 2 was not recovered and is most likely buried under about four feet of soil under a mound from previous road construction. An attached picture shows my friend standing at the location where RM2 should be. The AZ Mark (reset) was easily recovered and is located near the Hwy 140 / N Poe Valley Rd junction, a half mile south of the UNDERPASS series. The NGS datasheet description is adequate for recovery with the following exceptions: The railroad underpass mentioned has been removed and is now known as the OC&E Woodsline State Trail (Rails to Trails) trail; and power pole 68 mentioned in reference to locating the AZ mark has been removed as well.
