Fall while scrambling, Mount Niles, Yoho National Park, July 24th, 2011


At 1700, a group of 11 people were descending the scrambles route on the west ridge of Mount Niles. On the descent, one of the party members fell and tumbled 100 metres over steep broken terrain. The patient sustained injuries to her left arm and chest area. She did not lose consciousness, nor did she have difficulty breathing. The party was able to talk to the person at the trailhead via radio who then contacted 911.

Three Visitor Safety (VS) Specialists responded to the area in a helicopter. Another VS Specialist established a staging area at the Sherbrooke Lake Trailhead, and Banff EMS were dispatched.
The patient was packaged and slung off the mountain and then passed on to EMS. Due to the lateness of the day, the rest of the party was transported to the trailhead via helicopter.

Analysis

Scrambling and mountaineering can be dangerous activities. It is essential to have proper training and equipment, and gradually build personal experience in order to stay safe. This group consisted of a variety of people of various experience levels. Some people had appropriate equipment for the climb (mountaineering boots, crampons and ice axe), and others did not.

The subject was lucky to survive such a fall. This positive outcome was aided by the amount of snow on the scree slope where she landed, which helped cushion her fall. During a typical summer season, this slope would have been snow free by the end of July. Finally, the group was organized enough to have a communications plan which enabled the Visitor Safety team to quickly come to the rescue.
