OSHD Dot Martin series - Brookings, OR - U.S. Benchmarks on Waymarking.com

While logging two nearby NGS reference disks on the SW and SE ends of Dot Martin Bridge on Hwy 101, I discovered four more Oregon State Highway Division reference disks imbedded in the sidewalk, two on the south middle portion of Dot Martin Bridge and two on the north middle portion of Dot Martin Bridge.

All four reference disks found had different elevation stampings on them. The following disks and elevation stamping info:

OSHD Reference Disk 39.60 (located on the S/SE side of bridge)
OSHD Reference Disk 40.37 (located on the S/SW side of bridge)
OSHD Reference Disk 40.24 (located on the N/NW side of bridge)
OSHD Reference Disk 40.30 (located on the N/NW side of bridge)
