A 31-year-old snowmobiler from North Dakota died Wednesday after being buried in an avalanche in the Henderson Peak area near Cooke City.
The Park County Sheriff’s Office received a report at about 1:30 p.m. of an individual partially buried and not breathing.
Search and Rescue members were dispatched from Cooke City, according to a release from Undersheriff Scott Hamilton.
According to another release, the man had been riding with a friend about 100 yards off the trail when the avalanche occurred.
The 31-year-old man was reportedly buried in about 7 feet of snow. He and his riding partner both had avalanche beacons.
The friend located and unburied the man, which took about minutes 20, and performed CPR.
Search and Rescue also attempted CPR when they arrived, but the snowmobiler was pronounced dead at the scene.
A later release reported that two snowmobilers about 100 yards off the trail triggered the avalanche after a fracture in the snow traveled uphill.
The incident is under investigation, and the name of the victim is not being released at this time.
Skiers and snowmobilers are asked to use extreme caution due to the recent heavy snowfall.
The Gallatin National Forest Avalanche Center early Wednesday issued a backcountry avalanche warning for its whole advisory area.
The center said the danger for a slide is high in the Bridger, Gallatin and Madison ranges, the Lionhead area outside West Yellowstone and the mountains around Cooke City.
It cites heavy snowfall that's created instability and the potential for natural avalanches.
The center advises people not to travel in areas at risk for slides.
The warning lasts until 6:30 a.m. Friday.
