A crevasse is a deep, wedge -shaped opening in a moving mass of ice called a glacier. The bottom of the deep sea has several features that contribute to the diversity of this habitat. A tunnel was driven into the sloping surface of the ice towards a crevasse about a foot wide. The depth value is measured from the highest to the lowest accessible cave point. Mapping where crevasses appear is equivalent to mapping where the ice tensional stresses are highest. At the top, the crevasse was a narrow crack covered with foot-deep snow, thick enough to have obscured it from above. 8. 1 Where is the largest crevasses in the world?

They can reach up to 10 meters wide and are usually found in transverse crevasses on ice sheets and flat areas of a glacier. A crevasse is a deep, wedge-shaped opening in a moving mass of ice called a glacier. The ice now behaves ductile rather than brittle below 50 meters, so it will stretch and fold instead of fracturing under stress. She also climbed Mt Lhotsethe world's fourth-highest peak . Crevasses are also the places where meltwater drains down to the base of the ice. This is another one in Georgia, and there is a good chance it is the world's deepest cave. Kjeragbolten is a boulder wedged in a mountain crevasse by the edge of the Kjerag mountain in Lysefjord, near Stavanger.
