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 bergschrund (from the German for mountain cleft) 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, who sometimes abbreviate "bergschrund" to "schrund". Bergschrunds extend to the bedrock and can have a depth of well over 100 metres (330 ft).

Crevasse – A deep crack, or fracture, in an ice sheet or glacier; Corrie – An amphitheatre-like valley formed by glacial erosion or cwm; Cove (mountain) – Small valley in the Appalachian Mountains between two ridge lines; Dirt cone – Depositional glacial feature of ice or snow with an insulating layer of dirt
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.

Crevasse rescue (or crevasse-extraction) is a set of techniques in mountaineering where climbers use their equipment to pull a climber, who has just fallen into a crevasse, to safety. [1] Crevasse rescue is considered a core skill set in alpine climbing, but difficult to do efficiently. [1] [2] It is typically encountered by rope teams on ...
Erosional landforms. As the glaciers expand, due to their accumulating weight of snow and ice they crush, abrade, and scour surfaces such as rocks and bedrock.The resulting erosional landforms include striations, cirques, glacial horns, arêtes, trim lines, U-shaped valleys, roches moutonnées, overdeepenings and hanging valleys.
