These glacial potholes were formed about 10 to 11 thousand years ago as the last glacier melted. Sand and gravel caught in the eddies and whirlpools of the water of the melting glacier was swirled with such force that it literally drilled holes into the rock, forming the so-called potholes. There are more than 80 potholes at this location. The depth of the deepest pothole is 60 feet deep.
