Crevasses can be up to 20 meters wide (65 feet), 45 meters deep (148 feet), and hundreds of meters long. The Antarctic continental shelf appears generally narrow and unusually deep, its edge lying at depths up to 800 m (2,600 ft), compared to a global mean of 133 m (436 ft). The ice is then said to be behaving as a brittle solid. Crevasses usually form in the top 50 meters (160 feet) of a glacier, where the ice is brittle. Only in the ocean are the. They extend from the glacier's margin and are concave up with respect to glacier flow, making an angle less than 45 with the margin. . There, the crevasse. . 1 What is the deepest crevasse in the world? He was 68. To detect subtle crevasses, you need to look for faint linear offsets in the snow, and, if you find one, probe it with an ice axe or a pole to see how thin and wide it is. If all the ice covering Antarctica , Greenland, and in mountain glaciers around the world were to melt, sea level would rise about 70 meters (230 feet). A thin layer of ice or snow frequently covers crevasses. I felt as if I were underwater -- it was rapture.

Continental ice sheets smooth and round the terrain while mountain glaciations tend to ________. How deep are glacier holes? Splaying crevasses appear along the edges of a glacier and result from shear stress from the margin of the glacier and longitudinal compressing stress from lateral extension. A crevasse originated from French word "crevace" meaning wide crack that can run from a few meters to kilometers found in a snowfield or glacier. If there is no appreciable water circulation into and out of a bottom crevasse, this water must freeze to the walls of a bottom crevasse with a cold ice mass on a continuous basis.
