Dial 911 and be prepared to describe the nature of the accident, how many were involved, where on the mountain the accident occurred and where the party members currently are, any known injuries. Send one or two members of your party to the upper terminal of the Magic Mile Chair lift, or to Timberline Lodge for help. The majority of your party should stay with the injured climber keeping them warm and encouraged. DO NOT MOVE THEM unless you are in a life threatening situation. Use standard first aid procedures to stop bleeding.
Symptoms are loss of feeling and white, dead-looking skin.
Stay warm, move around, and return to the lodge and medical attention as soon as possible. Do not attempt to thaw frostbite on the mountain. The best medicine is prevention. Proper clothing, hydration, and eating is critical to preventing hypothermia. Be aware of how your body feels and if you start to get cold, take actions immediately to stay warm and dry.
