Avalanches still pose threat in Bighorns

SHERIDAN — The last time a person died from an avalanche in the Bighorn Mountains was in 2016. According to a report published by the Bridger-Teton Avalanche Center, a 39-year-old snowmobiler died in the area near Hunt Mountain Road Feb. 19, 2016.

While avalanche deaths in the Bighorns are less common than other areas of the state, avalanches are not random occurrences in the local mountain range.

Sheridan County Emergency Management reported an avalanche Feb. 3 of this year.

Jeff Shanor has been snowmobiling in the Bighorns most of his life. Shanor said there needs to be more awareness in the Bighorns about the dangers of avalanches.

The Bighorns have an area off U.S. Highway 14A that is prone to avalanches. Bighorn National Forest Public Affairs Officer Sarah Evans Kirol said there is a sign posted, warning those who are traveling down the trail. The avalanche area is near a groomed trail used by snowmobilers.

Areas off of groomed trails pose avalanche danger and the U.S. Forest Service cannot place a sign on every hill where an avalanche could occur, Evans Kirol said.

Hills that are primed for avalanches have a slope between 30-45 degrees. Other degrees of slopes can have avalanches but 30-45 degrees is the primary range for avalanches, Evans Kirol said. North facing hills have a higher chance of having avalanches.

As snow falls throughout the winter, different layers form. At a certain point, there is too much weight on the slope and gravity takes over, sending the accumulated snow down the mountain side.
