Petit Manan National Wildlife Refuge and Acadia National Park manage several of the scattered landmasses within this coastal Maine landscape, where the Atlantic Ocean meets a complex archipelago. The map reveals a maritime environment defined by numerous named ledges and islands that serve as crucial markers for navigation. Larger features like Marshall Island and Johns Island stand out alongside smaller, descriptively named outcrops such as Sally Prude Ledge, Johns Island Dry Ledge, and Johns Island Sunken Ledge.
