Observer Notes:A snowmobiler was reported to have been riding downward on a steep slope when he triggered a large slab avalanche. The rider deployed an avalanche airbag, was overtaken by the slide and was buried under 2 to 4 feet of avalanche debris. He was located and excavated in 5 to 10 minutes by three companions but did not survive. Our sincere condolences are extended to his family and friends. This hard slab was 3 to 5 feet thick and failed on faceted snow that formed earlier in the season. The crown of the avalanche was measured to be 5 feet deep.
