Glacier

glaciersglacialglaciated
A crevasse is a deep crack, or fracture, found in an ice sheet or glacier, as opposed to a crevice that forms in rock.
Glaciers slowly deform and flow due to stresses induced by their weight, creating crevasses, seracs, and other distinguishing features.

Serac

seracssérac
Crevasses often have vertical or near-vertical walls, which can then melt and create seracs, arches, and other ice formations.
A serac (originally from Swiss French sérac) is a block or column of glacial ice, often formed by intersecting crevasses on a glacier.

Crevasse rescue

rescue
Anyone planning to travel on a glacier should be trained in crevasse rescue.
Crevasse rescue is the process of retrieving a climber from a crevasse in a glacier.

Snow bridge

snowbridgesnow bridgessnow-bridge
A crevasse may be covered, but not necessarily filled, by a snow bridge made of the previous years' accumulation and snow drifts.
A snow bridge is an arc across a crevasse, a crack in rock, a creek, or some other opening in terrain.

Shear stress

shearshearingwall shear stress
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.

Arch

Crevasses often have vertical or near-vertical walls, which can then melt and create seracs, arches, and other ice formations.

Stratigraphy

These walls sometimes expose layers that represent the glacier's stratigraphy.

Ice sheet

A crevasse is a deep crack, or fracture, found in an ice sheet or glacier, as opposed to a crevice that forms in rock.

Stress (mechanics)

stressstressestensile stress
Longitudinal crevasses form parallel to flow where the glacier width is expanding. They develop in areas of tensile stress, such as where a valley widens or bends. They are typically concave down and form an angle greater than 45° with the margin.

Northeast Glacier

Yapeyú
Northeast Glacier is a steep, heavily crevassed glacier on the west side of Hemimont Plateau, 21 km long and 8 km wide at its mouth, which flows from McLeod Hill westward and then south-westwards into Marguerite Bay between the Debenham Islands and Roman Four Promontory, on the west coast of Graham Land, Antarctica.

Mountain warfare

Mountain Combatmountain infantrymountain
Mountains at any time of year are dangerous – lightning, strong gusts of wind, rock falls, avalanche, snow pack, ice, extreme cold, glaciers with their crevasses and the general uneven terrain and the slow pace of troop and material movement are all additional threats to combatants.

Ice rise

The resulting tension forms crevasses around the ice rise.

Quartermain Glacier

Leslie Bowden Quartermain
Quartermain Glacier (-67.01667°N, -65.15°W) is a well-defined, highly crevassed glacier on the north side of Fricker Glacier, from which it is separated in its upper reaches by Mount Kennett.

Couloir

couloirsglacier-couloirs
A couloir may be a seam, scar, or fissure, or vertical crevasse in an otherwise solid mountain mass. Though often hemmed in by sheer cliff walls, couloirs may also be less well-defined, and often simply a line of broken talus or scree ascending the mountainside and bordered by trees or other natural features.

Sørsdal Glacier

Sørsdal Glacier (-68.68333°N, 78.25°W) is a heavily crevassed glacier on the Ingrid Christensen Coast of Princess Elizabeth Land in Antarctica, 15 nmi long, flowing westward along the south side of Krok Fjord and the Vestfold Hills and terminating in a prominent glacier tongue at Prydz Bay.

Nera Gorge-Beușnița National Park

Cheile Nerei-BeușnițaCheile Nerei – Beușinta National Park
Nera Gorge-Beușnița National Park with an area of 36.758 ha was declared natural protected area by the Law Number.5 of March 6, 2000 (published in Romanian Official Paper Number.152 on April 12, 2000) and represents a mountainous area (mountain peaks, cirques, crevasses, caves, valleys, canyon s, waterfalls) what shelters a large variety of flora and fauna; some of the species are endematic or very rarely.

Icefall

An icefall is a portion of certain glaciers characterized by rapid flow and a chaotic crevassed surface.

Ninnis Glacier

Ninnis
Ninnis Glacier (-68.36667°N, 147°W) is a large, heavily hummocked and crevassed glacier descending steeply from the high interior to the sea in a broad valley, on George V Coast in Antarctica.

Zeus Ridge

Zeus Ridge (°N, °W) is a heavily crevassed, steep-sided, ice-covered ridge, the main part rising over 1,675 m, extending northwest from Mount Francais between the Achaean and Trojan Ranges in central Anvers Island, in the Palmer Archipelago.
