Isle Royale National Park defines the southwestern terminus of this remote Lake Superior island, where the isolated settlement of Windigo serves as a primary access point. The landscape is characterized by the prominent parallel elevations of Minong Ridge and Greenstone Ridge, which create a distinctive linear topography extending northeast. These ridges dictate the drainage patterns of inland waterways like Washington Cr and Grace Cr, which flow into the sheltered waters of Washington Harbor and Grace Harbor.
