holdentumbrl: Crevasse Crevasses are cracks that form in glaciers and can range from just a few inches across to over 40 feet (12 m.), and can be over 100 feet (30.5 m.) deep. Crevasses usually run horizontally on a steep slope, and more parallel with the flow of the glacier in the more open, flatter areas. The very large horizontal crevasse at the upper end of a glacier is called a bergshrund. These glacial “dead-fall traps” often get covered with snow, making them impossible to see, which only makes glacier travel all the more hazardous.
