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 ...
Touching the Void is a 2003 survival documentary film directed by Kevin Macdonald and starring Brendan Mackey, Nicholas Aaron, and Ollie Ryall. The plot concerns Joe Simpson and Simon Yates' near-fatal descent after making the first successful ascent of the West Face of Siula Grande in the Cordillera Huayhuash in the Peruvian Andes, in 1985.
These crevasse channels are essentially miniature distributary systems and can have many of the features that larger fluvial bodies possess, like levees. [4] A crevasse-splay sequence typically begins with an erosive base, followed by the deposition of coarse bed load sediment and transitioning to finer suspended sediment as energy decreases ...
A crevasse splay is a sedimentary fluvial deposit which forms when a stream breaks its natural or artificial levees and deposits sediment on a floodplain. A breach that forms a crevasse splay deposits sediments in similar pattern to an alluvial fan deposit. Once the levee has been breached the water flows out of its channel.

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]
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 ...
