Isle Royale National Park occupies the vast majority of this maritime survey, illustrating the remote archipelago's western reaches within the cold waters of Lake Superior. The map centers on the open water and the rugged north-south boundary of t63n r39w, showing the isolated outcrops and landforms that define the entrance to the harbor areas. At the northern edge, Washington Island stands as the primary landmass, accompanied by smaller navigation markers like Bottle Island, North Rock, and South Rock. This 2017 edition provides a clear record of the shoreline and protected wilderness boundaries of Keweenaw County, focusing on the preservation of the island's natural state and its immediate aquatic surroundings.
