Describe the sequence of events that occurs after Ralston and his friends ski Resolution Peak.

Once Ralston and two of his friends ski Resolution Peak, an avalanche approachs and all three tumble in the snow. Chad is the first to free himself but loses his gloves. He hears Aron close by and digs him out barehanded until Ralston's shovel is exposed. With the both of them free, they find Mark and see he is devoid of oxygen and completely buried. They get Mark warm in a down sleeping bag and all are able to ski back to the cabin and into safety.
