Long Description:
From the USGS page:

"DESCRIBED BY COAST AND GEODETIC SURVEY 1941 1.3 MI S FROM IRVINETON. ABOUT 1.3 MILES SOUTH ALONG THE PENNSYLVANIA RAILROAD FROM IRVINETON, WARREN COUNTY, ABOUT 170 FEET NORTH OF THE CENTER OF A ROAD CROSSING, AT BRIDGE 48.8, IN THE TOP OF THE NORTH END OF THE WEST ABUTMENT, 6.6 FEET WEST OF THE WEST RAIL, AND ABOUT 1.5 FEET LOWER THAN THE TOP OF THE RAIL. A STANDARD DISK, STAMPED C 139 1941."

The tracks have been removed and the land is part of the Allegheny National Forest. The disk can be found along a road leading south from Irvine, Pennsylvania with the sign Dunns Eddy. There is a small parking area to the south of the bridge on the east side of the road which can hold about four cars. The parking is for a foot trail in the ANF which begins to the north of the old railroad bridge.
