Isle Royale National Park dominates the southern portion of this coastal sheet, representing a remote wilderness area within Michigan's Keweenaw County. The map documents the northern reaches of the island as it meets the expansive waters of Lake Superior. A significant geopolitical boundary is represented by the Canada United States of America international border, which angles through the open water north of the island. The topography focuses on the interface between the national park's protected shoreline and the deep lake waters, offering a detailed perspective on the maritime boundary that separates these two nations in the middle of the Great Lakes.
