1947 Map of Plum Island

USGS Topo · Published 1948

About this map

Plum Island and its surrounding archipelago dominate this maritime survey, illustrating the strategic and navigational landscape of eastern Suffolk County shortly after World War II. The island itself is largely occupied by a military reservation and the installations of Fort Terry, featuring an intricate network of buildings and roads concentrated on its northern and eastern ends. A Ferry Landing on the western shore and a Lighthouse on the southwestern tip suggest the isolation and tactical importance of this outpost situated within the turbulent waters of Plum Gut. To the east, the smaller outcrops of Great Gull Island and Little Gull Island further define the passage between Long Island Sound and Block Island Sound, while the southern reaches identify a USC&GS Ruin at Gardiners Point, offering a glimpse into the region's earlier coastal surveying history.
