1921 Map of Great Wass Island

About this map

Great Wass Island and the intricate archipelago of Jonesport define this coastal survey of the Maine shoreline just after the First World War. The map details a complex maritime landscape of deep harbors and tidal narrows, including the Main Channel Way and the sheltered waters of Mistake Harbor. Navigation aids and safety installations are prominent, specifically the Moose Peak L H on Mistake Island and a Coast Guard Sta positioned on the western shore of the main island. From the rugged protrusion of Moose Neck to the outlying Seahorse Rock, the chart captures a moment when the regional economy remained deeply tied to the sea. Notable family-named landmarks like Stevens Island, Plummer Island, and Alleys Pt provide essential geographic points for genealogists tracing the coastal history of Washington County.
