2018 Map of Machias Seal Island

About this map

Machias Seal Island stands as the primary terrestrial feature in this maritime survey, situated within the vast expanse of the Atlantic Ocean off the coast of Maine. This 2018 survey by the U.S. Geological Survey highlights the sparse but critical navigational hazards of the area, including the small outcrop of North Rock and the submerged hazard of North Shoal. Located in the vicinity of Cutler, Washington County, the map provides a precise look at these remote features which have long been significant to maritime navigation and regional bird conservation efforts. The isolation of these features from the mainland illustrates the specialized nature of coastal boundary mapping in the far northeastern United States.
