Quick Answer
To navigate a crevasse safely in glacier areas, use a rope system, anchor securely, and descend slowly and carefully, often with the aid of specialized equipment and a partner.
Assessing the Crevasses
When approaching a glacier, identify potential crevasses by looking for signs of cracking, such as uneven ice surfaces, dark lines, or recent rockfall. Use a crevasse bridge or a rope system with anchors to cross the glacier, maintaining a safe distance from the edges. Always check the ice temperature before attempting to cross.
Descending a Crevasses Safely
Use a rope system with a minimum of 30 meters (100 feet) in length, and ensure that at least one partner is below you to provide a safety line. Anchor the rope system to stable ice formations or boulders, using a minimum of two anchors spaced 15 meters (50 feet) apart. Descend slowly, controlling your rate of descent by using the rope to slow down or speed up.
Emergency Protocols
In the event of a crevasse fall, remain calm and try to find a handhold or a place to anchor your rope. If you are unable to self-rescue, signal for help using a whistle or a mirror, and wait for assistance from your partner or a rescue team. Always carry a crevasse rescue kit, which should include a rope, anchors, and a pulley system for lifting victims to safety.
