- Description
- Two snowmobilers were riding at the base of a slope in a feature known as Bowl 3 in the Oasis snowmobile area south of Valemount. The avalanche was remote-triggered close to the edge of the bowl at a point where the riders were approximately 20 m from the toe of the slope. One person managed to ride away from the avalanche, while the other was fully buried. The survivor was able to locate the buried victim but they were found to be unresponsive. The avalanche ran on a layer of facets near the base of the snowpack. The crown depth was reported to be between 80 and 120 cm.
