JACKSON, Wyo. (AP) — A 35-year-old Utah man has died in an avalanche in southwestern Wyoming.

Officials with the Bridger-Teton Avalanche Center say Brennan Walpole of Spanish Fork, Utah, was with a group of 15 to 18 riders when the slide was triggered at about 1 p.m. Friday.

Avalanche Center Director Bob Comey tells the Jackson Hole News & Guide that the group was able to dig Walpole out of the snow after 8 to 10 minutes, but he was unconscious. They began CPR, sent an emergency alert using a satellite messenger and a search and rescue responders arrived by 3 p.m. Walpole was flown to the hospital in Idaho Falls, Idaho, where he died.

Two other snowmobilers were partially buried, but escaped without injury.
