I recovered this U.S. Coast & Geodetic Survey benchmark from 1954 in poor condition since the concrete monument has eroded badly on all sides and the disk is slightly loose in its setting. This disk is also listed on a topography map as 'BM 4208'. The NGS datasheet description is adequate for station recovery although Potter's Mill mentioned no longer exists. My more accurate coordinates will place you very close to this mark.

NGS datasheet info:

01/01/1954 by CGS (MONUMENTED) DESCRIBED BY COAST AND GEODETIC SURVEY 1954 4.2 MI NW FROM LOOKOUT. 4.2 MILES NORTHWEST ALONG A GRAVELED ROAD FROM THE POST OFFICE AT LOOKOUT, ABOUT 180 YARDS SOUTHEAST OF THE JUNCTION OF A DIRT ROAD LEADING WEST TO POTTERS MILL, 87 1/2 FEET SOUTH OF AND ACROSS THE ROAD FROM THE APPROXIMATE CENTER OF A WOODEN GATE, 32 1/2 FEET SOUTHWEST OF THE CENTER LINE OF THE ROAD, 2.1 FEET NORTHEAST OF A WITNESS POST, ABOUT LEVEL WITH THE ROAD, AND SET IN THE TOP OF A CONCRETE POST PROJECTING 0.6 FOOT ABOVE THE GROUND.
