Over 40 participants attended the avalanche awareness class in West Yellowstone. It was one of the best turnouts ever for this particular class. It’s great to see rider enthusiasm for avalanche education. #avalancheeducation #gnfacobs #mtavalanche

During the snowmobile avalanche awareness class in West Yellowstone we found a poor snowpack structure in the Lionhead area. It won’t take much new snow and wind to crest highly unstable conditions. Unfortunately, this problem will persist for a long period of time. #gnfacobs #poorsnowpackstructure #lionhead #facets
