crevasse
1. A deep fissure in the surface of a glacier, caused when tensile stress overcomes the shear strength of ice in the brittle upper few metres. Appropriate tensile stresses are typically developed when a glacier moves over a convex slope.
2. A breach in a levee along the bank of a river, through which flood water may flow and produce crevasse splays. (See crevasse deposit, 2).
