SLIP ON SNOW, FALL INTO BERGSCHRUND, CLIMBING UNROPED
British Columbia, Selkirk Mountains, Mount Thor
On August 10, 1986, a party of two left camp to attempt a new route on the southeast face of Mount Thor. After a rock climb estimated at 5.7 and 5.8 in places, they were stopped by a 5.9 crack about one and a half pitches from the summit. They rappelled back down. At the bottom of the last rappel, the first one down (40) found himself on a small ledge, about two meters above the iced-up bottom of a small bergschrund, and level with its lip about one meter away.
The choice was between downclimbing and stepping across. Across, the snow looked soft, and the slope beyond was steep, but not long, and apparently with a good runout. He stepped across. It turned out that the snow was hard, and his feet slipped from under him, and he started to slide—into a second bergschrund that could not be seen from the bottom of the rappel. He hit the far side of the bergschrund feet first, then bounced back and fell into the bergschrund.
The second climber hurried down and got him out. The injured climber took pain medication and the other returned to camp for help. A helicopter was called by radio, a club rescue team got him down a snow slope and he was flown out. He was found to have a broken right heel and severely sprained right ankle.

A classic case of a rappel not going quite far enough. Beyond the protection of the rope, it really is necessary to check and know the terrain below. The injured climber was very experienced and physically fit. Fortunately, he was fully dressed with gaiters, big boots, hard hat, and full-sized climbing pack, all of which provided protection. (The hard hat had fresh scratches on it.) (Source: Fred Thiessen and Steve Horvath, Kootenay Mountaineering Club)
