Accident Summary

PRELIMINARY: A group of three snowmobilers were riding in the East Fork of Chalk Creek, in the western Uinta Mountains. Rider 1 was climbing a steep chute on the west face of Humpy Mountain when he triggered the avalanche. He was caught and buried. Rider 1 and his companions had avalanche transceivers, but no shovels. A second group of snowmobiles, equipped with shovels, came upon the avalanche and assisted with the companion rescue. Rider 1 was buried for 30 to 40 minutes and four to five feet deep. The group began CPR. Authorities were notified and reached the avalanche by helicopter about 40 minutes after Rider 1 was excavated. They flew Rider 1 to a hospital in Evanston, Wyoming, where he was pronounced dead.
