The Falls River flows through Baraga County on MichiganâÂÂs Upper Peninsula and enters Lake Superior at LâÂÂAnse Bay on the shoreline of LâÂÂAnse. The stream drains forested uplands south of the bay, dropping across a short series of rock ledges and small gorges before reaching Lake Superior.
Headwaters arise in wetlands and short lakes in the hills south of LâÂÂAnse. The river flows generally north, steepening as it approaches LâÂÂAnse Bay. Along the lower course it forms several cascades and falls before entering Keweenaw Bay at the village waterfront.
