A snowmobiler from Idaho Falls is missing and presumed dead after this snowmobile was found partially buried in avalanche debris near Reas Peak south of West Yellowstone. The man reportedly remains unaccounted for.
The Gallatin National Forest Avalanche Center said in a social media post that the incident was on the Caribou-Targhee National Forest in the Centennial Range.
Rescue efforts will continue today.
The Centennial Range is out of range for the Gallatin National Forest Avalanche Center forecast range, but they said that the area has a similar snowpack structure to the Lionhead area and mountains around West Yellowstone.
The southern mountains have received a heavy amount of snow over the past 36 hours and the snowpack reportedly remains under a tremendous amount of stress. The center said it will be possible to trigger entire slopes from the bottom or from a distance. Travel in avalanche terrain is not recommended.
As more snow and wind impact the area today, very dangerous avalanche conditions exist.
Natural and human triggered avalanches will be likely on wind loaded slopes which have a high avalanche danger. Human triggered avalanches are likely on non-wind loaded slopes which have a considerable avalanche danger.
