Splitting Cliffs

Late-afternoon summer sunlight casts a warm glow on the banded sandstone cliffs of Pictured Rocks National Lakeshore. Water has worked this shoreline in many ways to make it look like this. The walls of split rock in the foreground were left behind as a combination of freeze-thaw cycles and pounding waves removed rock particles between them and the current cliffs. Mineral stains running down the rocks got there by dissolution, as water heavily laden with minerals seeped out then down the sides.
