1947 Map of Plum Island

USGS Topo · Published 1947

About this map

Fort Terry dominates the landscape of Plum Island in this post-war military survey, showing the installation's network of roads and structures at a time of significant transition. Situated where Long Island Sound meets Block Island Sound, the island's strategic maritime position is marked by a Lighthouse at its western tip near Plum Gut. The map records the approximate military reservation boundaries as they stood in 1947, including the Ferry Landing that served as the primary link to Orient Pt on the mainland. Further east, the small outposts of Great Gull Island and Little Gull Island are detailed, the latter featuring its own Lighthouse. To the south in Gardiners Bay, the map captures the USC&GS Ruin at Gardiners Point, providing a specific record of coastal survey markers and military presence in this critical New York waterway.
