The Black River is a river on the Upper Peninsula of the U.S. state of Michigan, flowing mostly in Gogebic County into Lake Superior at . Its source at is a boreal wetland on the border with Iron County, Wisconsin. The northern section of the river, within the boundaries of the Ottawa National Forest, was designated a National Wild and Scenic River in 1992. At the Lake Superior mouth of the Black River is Black River Harbor, a former fishing station where commercial fishermen brought in cargoes of lake trout. The North Country Trail crosses the river here via a suspension footbridge. Waterfalls The Wild and Scenic River section of the Black River of Gogebic County is known for the many waterfalls produced as the river tumbles down from near Copper Peak to Lake Superior. The river drops more than over five separate named cataracts beginning from its mouth. The first three named falls are smaller, farther apart, and have limited access. Some of these waterfalls are easily accessible from the parallel County Road 513 (Black River Road) north of Bessemer, while other waterfalls require a more strenuous hike to see. Roadside trails provide access to Gorge Falls and Potawatomi Falls. The Black River Road was named a National Forest Scenic Byway in 1992. The trails to two of the Black River waterfalls, Gorge and Potawatomi, have been designated National Recreation Trails due to their unique stairway designs (to provide easier access down the steep slopes) and observation platforms. Narrows, Chippewa, and Algonquin Falls The first three waterfalls on the Black River as it approaches Lake Superior are Narrows Falls, Chippewa Falls, and Algonquin Falls. They are the three smallest named waterfalls on the river. Narrows and Algonquin Falls are technically rapids or cascades. Chippewa Falls drops nearly over boulders and dead tree limbs. These area have limited access and are not often visited. Great Conglomerate and Potawatomi Falls Great Conglomerate Falls is the southernmost (the Black River flows north) of the more publicized falls and the first large waterfall on the river's approach to Lake Superior. The river drops around a large piece of conglomerate rock, boulders and tree trunks into a deep gorge. Potawatomi Falls drops nearly in two sections around a piece of conglomerate rock, similar to Great Conglomerate Falls. Gorge and Sandstone Falls At Gorge Falls, , the Black River constricts to about across and drops
