Apostle Islands National Lakeshore, WI
Though it hadn’t occurred in a long time, the Ice Caves of the Apostle Islands graced the Northland with their beauty once again during the 2013-2014 winter season. They are formed when the waves of Lake Superior splash against, and into, the Apostle Islands Sea Caves when the air temperature is cold enough to freeze the water to the rock of the cliff. The waves continue to build up until the caves are coated with ice and unique and beautiful formations are created. When thick enough, the ice formations will appear blue due to the minerals in the water and the thickness.
