2021 Map of Petit Manan Point OE S

About this map

The Atlantic Ocean dominates this maritime survey off the Maine coast, where the county boundary between Hancock Co and Washington Co extends into the open water. This 2021 edition focuses on several dangerous navigation hazards and prominent rock formations that break the surface of the sea. Among these named geological features are Old Man and the neighboring Big Black Ledge and Little Black Ledge. Further offshore, the Moulton Ledge serves as a critical marker for local mariners and coastal historians. The map provides a precise look at the maritime geography of the region at a time when digital GPS and satellite imagery have largely replaced traditional surveying methods, though these permanent ledges remain foundational to coastal navigation.
