1954 Map of Plum Island

USGS Topo · Published 1971

About this map

Plum Island Restricted occupies the center of this maritime survey, a location notably marked as the site of the U S Dept of Agriculture (Restricted) Dangerous Animal Diseases research facility. This mid-century coastal mapping captures the strategic and scientific isolation of the islands at the junction of Long Island Sound and Block Island Sound. To the southwest, the tip of the North Fork is anchored by Orient Point and the Orient Beach State Park, while a Ferry route connects the mainland across the turbulent waters of Plum Gut. The map records essential navigational aids like the Plum Island Lighthouse and Orient Pt Lighthouse, alongside several outlying hazards including Great Gull Island and Little Gull I. On the mainland, the Latham Cem provides a point of genealogical interest for local families.
