Manitou Island and the jagged eastern extremity of the Keweenaw Peninsula define this maritime landscape in Lake Superior. This survey documents a critical navigational threshold where the mainland terminates at Keweenaw Point and gives way to the open waters of the lake. The geography is characterized by several protected coastal features, including High Rock Bay, Keystone Bay, and the separate harbors of North Bay and South Bay on the island itself.
