The danger of a crevasse is that it may be covered by a bridge that conceals a yawning space below. /45m deep A crevasse opens in tiny increments, with each brittle fracture separating the ice by a millimeter or so. When the sun was shining, the grayness that I had experienced in my first crevasse was transcended by pervasive blue, pale and bright near thin spots in an overhanging bridge, dark and rich, deep down in.

At the scale of the glacier, the movement is steady and uniform, but at the scale of individual crystals of ice, the frantic migration of molecules from spots of higher to lower pressure causes the solid crystals of ice to recrystallize and change their shapes.

Theoretically, the weight of the ice limits crevasse depth to about 30 m. Below that there is typically enough compressive force in the ice to prevent cracks from opening. Early Everest Crevasse Crossing. Water-filled crevasses may reach the bottom of glaciers or ice sheets and provide a direct hydrologic connection between the surface, where significant summer melting occurs, and the bed of the glacier, where additional water may moisten and lubricate the bed and accelerate ice flow. These are the hidden gems in the secret world of crevasses. This ice-filled canyon reaches 3.5km (11,500ft) below sea level. What would Antarctica be like without ice?

Created by direct precipitation of water molecules from the still air of the crevasse interior, these hoar crystals are hexagonal in form with delicate, hoppered steps. Because of the frequency with which climbers break through the snow over a crevasse and fall in, crevasse rescue technique is a standard part of climbing education. Professor, School of Earth and Space Exploration at Arizona State University. A bottom crevasse is, of course, filled with water. You can usually see these shadows if a glacier only has a thin layer of snow or no snow. 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. The features are evidence that the glacial motion has been consistent for some time because they are so large and very well shaped. This ice-filled canyon reaches 3.5km (11,500ft) below sea level.
