The Black River carves a deep path through the Western Upper Peninsula in this survey, showcasing the area's transition from forest wilderness to recreation and transportation hub. The landscape is dominated by the Ottawa National Forest, where the Copper Peak ski flying hill and the Big Powderhorn Ski Area signify the importance of winter sports to the local economy near the Ironwood and Bessemer municipal boundaries. Numerous waterfalls, including Algonquin Falls, Chippewa Falls, and Rocky Rocky Falls, dot the river system, emphasizing the dramatic drops in elevation as the water moves toward Lake Superior.
