GENERAL KNOWLEDGE

Detailed explanation-1: -A crevasse is simply a deep crack in a glacier or ice sheet. Crevasses pose dangers to hikers and mountain climbers. A crevasse is a deep, wedge-shaped opening in a moving mass of ice called a glacier. Crevasses usually form in the top 50 meters (160 feet) of a glacier, where the ice is brittle.

Detailed explanation-2: -If you fall in a crevasse you can use the ice screw to secure yourself so you don’t fall deeper. The pulley and carabiners are for rescuing others. Two ice tools, crampons, rope, and several ice screws (basically, ice climbing gear) may allow you to climb out yourself.

Detailed explanation-3: -Crevasses Form by Glacial Movement Ice in the middle of a glacier tends to move more quickly than along the edges where it catches and grabs the underlying rock surface and cause crevasses to gape open. Crevasses usually have vertical walls and are up to 150 feet deep and as wide as 70 feet.
