About this map

Plum Island sits at the gateway between Long Island Sound and Block Island Sound, a landscape defined by its strategic maritime position. This modern survey details the island's isolated geography, featuring Plum Gut Harbor and prominent coastal markers like East Point and Pine Point. On the western shore of the Plum Gut passage, the tip of Long Island is visible at Orient Point, where the local road network terminates.

Navigational hazards and features are meticulously charted, from the Midway Shoal to the rocky outcrops of Old Silas Rock and Middle Shoal Rock in the area known as The Sluiceway. The established maritime corridors are evident through the Cross Sound Ferry route and the Intracoastal Waterway, which cross the state boundary between New York and Connecticut. For local historians, the inclusion of Latham Cem near Orient Point provides a specific point of genealogical interest among the coastal reaches of Gardiners Bay.
