Icy Falls, Cascade River, Cascade River State Park; Lutsen, Minnesota

The Cascade River drops over many waterfalls on its way to Lake Superior. This is the last, and the most photographed, of the falls. Cold winter weather changed it considerably! The golden-amber color in the water and ice comes from tannins.
