- Two skiers were caught in an avalanche near the McDermott Cabin 15 km east of Jaffray, BC. One skier was able to prevent himself being buried by the snow by clinging onto a tree but the other was carried down and buried. He was located by his companion but found to be deceased. The survivor was able to report back to the McDermott Cabin where they were staying with a larger party. The fracture line was reported to be 100 cm deep and the avalanche is presumed to have run on the mid-December persistent weak layer. The avalanche was triggered in a slightly steeper, slightly more open part of the slope and propagated upwards into an area that contained moderately dense timber. Slope angle was approximately 33 degrees.
