Crevassed terminus of Jakobshavn Isbræ

The glacier terminus (right) flows toward the fjord at speeds of 10 (winter) to 17 (summer) kilometers per year, before breaking off at the edge to form large icebergs that choke the fjord (left). The fast motion stretches the ice, creating deep crevasses visible across the glacier terminus.
