Beloit Glacier fluctuates betwen 125 and 250 feet high at water's edge depending on recent calving activity. Calving diminishes the face but it builds back up again quickly as the glacier descends to sea. Nonetheless, the glacier is in rapid retreat; you can spot bedrock becoming exposed at the base of the glacier. It was named after the Wisconsin college, as were most of the other glaciers in Blackstone Bay (Lawrence, Marquette, Concordia, Northland, and Ripon but not Blackstone).
