Blue Glacier also features a unique patch of tic-tac-toe crevasses at the base of the icefall. This small spot where sets of parallel cracks run perpendicular to one another is formed by a high spot in the bedrock that the ice must flow over.

Crevasses are deep fissures or cracks formed on snowfields due to varying glacier velocities. More the speed with which a glacier moves down, more are the chances of extension and formation of a crevasse. ... With expanding glacier width, longitudinal crevasses are formed. Crevasses are notoriously renowned for gulping...

Crevasse - Wikipedia, the free encyclopedia

A crevasse is a crack in an ice sheet or glacier. Crevasses often have vertical or near-vertical walls, which can then melt and create seracs, arches, etc.; these walls sometimes expose layers that ...

A crevasse is formed when there is tension on the brittle ice. A crevasse can usually become many meters deep. They usually get covered by recent snow fall. There are four types of crevasses. One is a transverse crevasse.

Occurs when ice cannot creep fast enough to to allow a glacier to adjust its shape under stress. An example of this is crevasses -formed where the tensile stresses are so great that the ice is pulled apart.

crevasse (krəvăs'), large crack in the upper surface of a glacier, formed by tension acting upon the brittle ice. Transverse crevasses occur where the grade of the glacier bed becomes suddenly steeper; longitudinal crevasses, where the glacier spreads over a wider valley or plain. ... How crevasses are formed?

Various features can be observed on the glacier surface, including crevasses, fissures that form from tensile stress in the glacier surface; icefalls, resulting from crevasses formed where the glacier hangs over a bedrock protuberance;

Glacier in Patagonia, Argentina. Deep cracks known as crevasses can be seen in the ice. These are formed when a glacier moves over an uneven surface. When the glacier reaches the sea, or as in this picture, a lake, the crevasses will fracture the ice to form icebergs.

Crevasses are formed on convex slopes where the ice-flow is stretched. During the summer and early in the season many crevasses may be obvious although some others may be poorly bridged. The great French climber, Louis Lachenal was killed falling into a crevasse on the Vallée Blanche while skiing in November.
