None ExperiencedBottom Line
I saw a significant amount of natural avalanche activity from Eagle Ck to Stanley. Based on the amount of snow blown into some crowns, most activity appeared to happen on more northerly aspects earlier in the storm (Monday evening/night) and then on E/SE aspects later in the storm (Monday night/early Tuesday morning). There was also some activity on middle elevation aspects that were not obviously affected by the wind. Many of the crowns appeared to be persistent slabs failing on the Dec 11th faceted layer.
