About this map

Cape Split and the sheltered waters of Cape Split Harbor anchor the northern edge of this coastal survey, where the rugged maritime geography of Washington County meets the Gulf of Maine. The landscape is defined by an intricate network of named islands and submerged hazards, ranging from Drisko Island and Nash Island in the west to the cluster around Stevens Island and Little Ram Island in the east.

Navigational landmarks like Tibbett Narrows and The Sands illustrate the complex seafaring environment near Western Bay. Named ledges and rocks, such as Batson Ledges, Stanley Ledge, and Seahorse Rock, dominate the southern reaches as the seafloor drops toward the open Atlantic Ocean. This map serves as a primary reference for the named landforms and hydrographic features that have shaped the local fishing and maritime history of the Addison area.
