2014 Map of Hewett Island

About this map

Hewett Island and the surrounding Muscle Ridge Islands define this maritime landscape in Knox County, where the granite-rich terrain meets the Atlantic Ocean. The map documents a dense archipelago of islands and submerged hazards, such as Hurricane Ledge and Lower Gangway Ledge, which have historically dictated the navigation of the Muscle Ridge Channel. A protected anchorage at Home Harbor sits between Hewett Island and Mink Island, reflecting the shelter-seeking patterns of local coastal trade and fishing vessels. The presence of Hurricane Island is particularly significant, once known for its extensive granite quarrying operations that shaped the architectural history of the eastern seaboard. From the larger landmasses like Whitehead Island and Sprucehead Island to isolated outposts like Two Bush Island, the survey provides a detailed look at the ledge-strewn waters and rocky outcroppings that characterize this part of the Maine coast.
