2021 Map of Old Man

About this map

The waters of the Grand Manan Channel dominate this maritime survey off the coast of Washington County. At the northern edge of the map, the small island known as Old Man stands as a navigational landmark, while the southern expanse is characterized by the open Atlantic Ocean. The seafloor topography includes Flowers Rock, a notable submerged or partially exposed feature that defines the local marine environment. This 2021 study reflects the modern nautical boundaries and bathymetric points of interest in this particular stretch of Maine's coastline, where the land-sea interface is reduced to a few critical rocky outcrops and deep-water channels.
