On the Throne in the northern Bridgers we found a layer of facets buried under a stiff wind slab. This layer propagated in stability tests with medium force. Fortunately, we did not observe any recent avalanche activity on this layer nor did we experience any cracking or collapsing. It appeared there wasn't enough of a load to create widespread instability. This will be something to pay attention to once more snow falls. #gnfacobs #buriedfacets #northernbridgers #goawayelnino

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
