2018 Map of Matinicus OE NE

About this map

Submerged hazards and navigation landmarks define this maritime survey off the coast of Maine. The map focuses almost entirely on the open waters of the Atlantic Ocean within Knox County, charting significant underwater features that have long challenged local mariners. Among these notable formations are Western Ear Ledge and Roaring Bull Ledge in the northern reaches, while Three Fathom Ledge marks a critical shallow point in the central waters. To the southwest, Eastern Ledge rises from the seafloor, providing a crucial reference point for coastal transit and fishing operations. This modern topographic study emphasizes the invisible geography of the sea, documenting the specific ledges and shoals that dictate the maritime patterns of the region.
