The Cannonsville Reservoir dominates the southeastern terrain of this 1960s survey, marking a significant transformation of the Delaware County landscape. As part of the City of New York Water Supply Reservation, the flooding of the valley floor reshaped local geography, visible here near the Trout Creek Bridge. To the north and west, the map shows a network of upland hamlets including Masonville, Ivanhoe, and Tacoma, connected by historic routes like Steam Mill Road and Gifford Road. The region is defined by heavy forestation, specifically the Masonville State Forest and Delaware State Forest, which cover the high ridges of Randell Hill and Clabber Peak. Genealogists will find value in the specific locations of the Austin Cem and Carroll Cem, as well as established community sites like the Brace Youth Camp.
