This station, a U.S. Coast and Geodetic Survey and State Survey standard disk, is located on the Rockingham Rail trail, formerly the Portsmouth Branch of the Boston & Maine Railroad, in West Epping, NH.
As found, it is badly damaged by an apparent theft attempt. Although about 40% of the disk is missing, the remainder still displays the designation, the cross hairs are still in place at the center, and is firmly seated.
A description I came up with is as follows:
In West Epping, from the center of the crossing at Depot Road, go east on the Rockingham Rail Trail for 1150 ft to the station on the left, a USC&GS&SS standard disk, stamped -C 18 1934- set in a small shelf of a large rock outcrop, 2 ft above the trail surface, 12 ft north from the trail center, 60 ft east from a 5 ft diameter twin pine tree, and 93 ft northeast from an orange carsonite marker post labeled AT&T No. 111.
There were no NHDOT papers available online for this mark, but the possible ID# for this mark might have been 147-0110.
The 1934 stamping is missing, but it is definitely a 1934 State Survey mark. Half a disk is better than no disk, but it's very disappointing to find such occurrences.
