A deep crevice or fissure, as in embankment; one of the clefts or fissure by which the mass of a glacier is divided.
A breach in the levee or embankment of a river, caused by the pressure of the water, as on the lower Mississippi.
Any large vertical crack in the surface of a glacier or snowfield.
A crack in the ice of an ice shelf or glacier. They're often covered with snow at the surface and so difficult to see.
A deep chasm that forms within glaciers. They can be more than 100 feet deep.
A deep, open crack in a glacier.
gaping crack in the brittle surface ice of a glacier
Crevasses form only when the slope of a glacier changes, an in Antarctica this happens near the coasts or in the mountain ranges. The center of the continent has slow-flowing glaciers which are safe to walk or drive on. Near the coasts, crevasses need to be filled with snow before they can be crossed by heavy sled trains.!-- google_ad_client = "pub-5254204592421200"; google_ad_width = 728; google_ad_height = 90; google_ad_format = "728x90_as"; google_ad_type = "text"; google_ad_channel =""; google_color_border = "EEFEE6"; google_color_bg = "FEFED6"; google_color_link = "00DDDD"; google_color_url = "9194FF"; google_color_text = "000000"; google_ad_channel ="9098506109"; //-- 10, D47, D80... Series of reference points between DdU (or more exactly its coastal station, Prud'Homme) and Dome C. Most are nothing more than a pole where to confirm GPS position but D10, D47 and D80 have Automatic Weather Stations. D10 is the actual organization and departure point of the Traverses. It's a few km from the coast and 10km away from DdU, hence its name, but don't go believing that this numbering scheme applies to the other D-something.
A deep tensional fracture formed on a glacier.
1. glacial geology A deep crack in the upper surface of a glacier. 2. natural levee A break in a natural levee.
a deep crack in glacial ice caused by the slow movement of the ice
The deep cracks in ice caused by ice movement.
A crevasse is a crack in a glacier. They can run deep into a glacier. Crevasses are formed when the slope on which a glacier flows becomes steeper, increasing the speed of parts of the glacier and reducing its thickness. Different parts of the same glacier are then travelling at different speeds over steep and gentle slopes. This places stress on the thin ice, causing cracks or crevasses to appear.
A deep, disguised crack in a glacier.
A fissure formed in a glacier, ice sheet, or ice shelf. Crevasses are often hidden by snow bridges.
A potentially large gap in a glacier caused by tension or shifting. On Everest crevasses can run 10 stories deep.
A crack in a glacier caused by rapid extension. Crevasses over 10 m deep would be healed by internal flow, but much deeper crevasses can be maintained by continued tension.
a deep crack in the glacier, like a massive ice whole
a large crack in the glacier formed by differential flow rate
an open fissure in the glacier surface
crack within a glacier. Can be near or on the surface and as such a danger to climbers. Can range from a few inches to tens of metres deep
A breach in a levee along the bank of a river through which floodwater may flow and produce sheetlike deposits of gravel or sandy sediment; or, a large, open fissure forming in a glacier as it moves and is deformed.
A crack or series of cracks that open in the surface of a moving glacier in response to differential stresses caused by glacier flow. They range in shape from linear to arcuate, in length from feet to miles. Their orientation may be in any direction with respect to the glacier flow. The deepest crevasses may exceed 100 feet. --------------------- Debris Cone A cone or mound of debris-covered ice, with a thick enough sediment cover to protect the ice from melting.
crack in a glacier surface; crevasses vary in width and depth and are often concealed by surface snow and thus pose hazard for climbers
A crack in a glacier surface, often very deep and sometimes concealed by a thin coating of snow, created by the movement of the glacier over underlying irregularities in terrain.
A fracture or split in a Glacier's ice. Crevasses tend to form perpendicular to tension in the snow pack and are thus most often seen as horizontal gashes across the face of a glacier. Crevasses are often hidden by thin layers of snow at their tops. Even when visible, crevasses pose a significant threat to passing climbers
Cracks in the ice formed when the ice moves over uneven rocks or when floating ice spreads.
A break in a levee allowing the river or lake to rush through to the protected land.
A deep crack in the brittle surface of a glacier.
Large near-vertical fracture open at the surface of a glacier and commonly a route for meltwater flow.
deep fissure in snow or ice usually found in glaciers. Climbers rope-up together and walk far apart in case one drops into a hidden crevasse, others on the rope may be able to stop the fall.
A deep, nearly vertical crack that develops in the upper portion of glacier ice.
A crack in a glacier surface of varying width and depth, caused by the movement of the glacier over underlying irregularities in terrain.
(1) Opening on a levee that allows for the drainage of water from the floodplain to the stream channel. (2) Fracture on the brittle surface of a glacier.
A crack in a glacier surface. Crevasses vary in width and depth and are often concealed by surface snow. Concealed crevasses are a hazard for climbers on glaciers.
A deep rift in a glacier, or in any other form of land ice, caused by its motion.
A crevasse is a crack or fissure in a glacier or snowfield, formed due to changes in glacier speed. An acceleration in glacier speed can cause extension and formation of a crevasse.
