More detailed information about the avalanche: 

Avalanche that went to the ground with a 3 foot+ crown near the ridge. Skinned past it on my way to the hose. Debree was several feet thick and a few snapped small diameter trees in the mix. Dug a few hand pits on the way up and found a dense wind crust with variable depths on top that sheared off with moderate force. I can confirm skiing was pretty terrible until about 8500 feet at the last steep pitch of lower dempsey don't. Lots of settlement in this last week as seen by the tree picture. Avalanche was likely from the wind event earlier this week.
