Observer Notes:A snowmobiler was in a steep terrain trap and triggered a small slab avalanche (app. 150 x 150 feet). He was pinned under the sled on his back. A partner was not able to assist. Other riders came by after an hour. They uncovered his face which was one foot under the snow, but he did not survive. This stiff wind slab failed on faceted snow that formed earlier in the season. The total snow depth in this concave terrain feature was only 2 to 3 feet deep. Our sincere condolences to all involved in this tragic incident.
