The Grand Portage Indian Reservation occupies this corner of the Arrowhead region, where the international boundary follows the Pigeon River as it flows toward Lake Superior. The landscape is defined by interior water bodies like Speckled Trout Lake and Taylor Lake, while the coastline features rugged inlets such as Deronda Bay and Cannonball Bay. The small settlement of Mineral Center sits at a crossroads within the reservation, serving as a focal point in a territory largely comprised of the Grand Portage State Forest and the Grand Portage National Monument. High-altitude vantage points are marked by the Mt Sophie Lookout Tower and Mt Maude Lookout Tower, indicating the importance of fire surveillance in these dense woods at the end of the 20th century. Topography here reaches its peak at the Partridge Falls along the Ontario border.
