2016 Map of Plum Island

About this map

Plum Island sits prominently at the threshold of the Long Island Sound and the Atlantic Ocean, serving as a critical maritime waypoint in this 2016 survey. The map details the island's isolation, marked by Plum Gut Harbor and the surrounding Plum Gut, which separates it from the tip of Long Island. This area is defined by its navigation-heavy geography, where the Cross Sound Ferry line bisects the waters, connecting New York and Connecticut across the Suffolk County and New London County maritime border. On the mainland, the village of Orient and its peninsula extend toward Orient Point, illustrating the gateway to the Block Island Sound. The map also captures several distinct hazards and landmarks, including Old Silas Rock, Middle Shoal Rock, and the precarious Bedford Reef, providing a clear picture of the complex seafaring environment near The Sluiceway.
