Transverse crevasses, Chugach State Park, Alaska. A crevasse is a deep crack that forms in a glacier or ice sheet. Crevasses form as a result of the movement and resulting stress associated with the shear stress generated when two semi-rigid pieces above a plastic substrate have different rates of movement. The resulting intensity of the shear ...
A crevasse may be as deep as 45 m (148 ft) and as wide as 20 m (66 ft). [11] A crevasse may be covered, but not necessarily filled, by a snow bridge made of the previous years' accumulation and snow drifts. The result is that crevasses are rendered invisible, and extremely dangerous to anyone attempting to traverse a glacier. [12]

A snow bridge across a creek. A snow bridge is an arc formed by snow across a crevasse, a crack in rock, a creek, or some other opening in terrain. [1] It is typically formed by snow drift, which first creates a cornice, which may then grow to reach the other side of the opening.
A bergschrund (from the German for mountain cleft; sometimes abbreviated in English to "schrund") is a crevasse that forms where moving glacier ice separates from the stagnant ice or firn above. [1] It is often a serious obstacle for mountaineers. Bergschrunds extend to the bedrock, and can have a depth of well over 100 metres (330 ft).
Firth – Scottish word used for various coastal inlets and straits; Fjard – Glacially formed, broad, shallow inlet; Fjord – Long, narrow inlet with steep sides or cliffs, created by glacial activity; Geo – Inlet, a gully or a narrow and deep cleft in the face of a cliff; Gulf – Large inlet from the ocean into the landmass List of gulfs
A randkluft (from the German for marginal cleft/crevasse) or rimaye (from the same French IPA:) is the headwall gap between a glacier or snowfield and the adjacent rock face at the back of the cirque [1] or, more loosely, between the rock face and the side of the glacier. In French, the word rimaye covers both notions of randkluft and bergschrund.
