Judge C. R. Magney State Park on Minnesota’s Lake Superior North Shore preserves the lower Brule River, where a steep descent to the lake creates cascades, gorges, and waterfalls. Its most famous feature, the Devil’s Kettle, split around rhyolite and long inspired speculation that part of the river vanished underground, a mystery largely settled in 2016 when flow measurements showed the water rejoins the river below the falls. Named for Clarence R. Magney, the park also reflects volcanic origins, glacial shoreline changes, Ojibwe and logging history, Depression-era forestry work, and a diverse forest and wildlife landscape.
