About this map

Hewett Island and the neighboring Muscle Ridge Islands anchor this coastal Maine survey, which details a complex maritime landscape of granite outcroppings and sheltered passages. The terrain is characterized by numerous small islands and hazardous reefs, including Hurricane Island and Graffam Island, which frame the central Home Harbor. This seafaring geography is defined by its navigational channels, such as the Muscle Ridge Channel to the northwest and Two Bush Channel to the south.

Evidence of human habitation is concentrated near the mainland edge on Sprucehead Island, where Island Rd provides the primary access. Beyond the larger islands like Andrews Island and Pleasant Island, the map records a high density of named submerged features and ledges, such as Hurricane Ledge and Two Bush Reef, illustrating the intricate shoreline and navigational challenges of Knox County's coastal waters in the early 21st century.
