Comments

Saw this avalanche on the Diving Board in Broads Fork, I'm thinking it avalanched Thursday or Friday of last week when we had the rain event. It seemed to be a glide avalanche that came out of the rock slabs up high then triggered a massive wet slide in the apron of the diving taking out the whole seasons snow-pack. The crown of the glide was at least 10ft deep and the debris pile was well over 30ft deep. There was also another crown below the glide crown that looked like it ran during the wind event after the storm. Multiple glide avalanches were triggered in the drainage I'll put them in my Observation.
