Crevasse in the Mozama Glacier on Mount Baker, Washington—Bob and Ira Spring

Fissure or crack in a glacier resulting from stress produced by movement. Crevasses range up to 65 ft (20 m) wide, 150 ft (45 m) deep, and several hundred yards long. Crevasses may be bridged by snow and become hidden, and they may close up as the glacier moves.
