Big Sky Ski Patrol triggered this avalanche during mitigation work in The Wave on 11/26/24... "2-3' deep on an ice crust just above the ground with a 2# shot in the Upper rodeo. Volume was limited as most of the snow was loaded just underneath the cornice, but still produced a sizeable size 2... Other paths in the Lenin region ran meaty wind slabs, full track with no significant step downs." Photo: BSSP

From obs.: "Triggered a small wind slab: -9600' -N aspect on the NW ridge of Sphinx Mountain -Strong SW wind

-Noticed oth er small crowns, likely triggered from another party traversing the north-facing bowl at similar elevations" Photo: S. Bonucci

From e-mail: "Photo attached from near top of hyalite peak, 11/2. Cracking in recent hard wind slab, I had to really jump hard to make this. Walked on many other hard slabs that were well bonded. Highly variable snowpack. I think you'd be most likely to get into trouble by popping out a small hard slab pocket like this and getting magic carpeted into some thinly covered terrain." Photo: B. VandenBos

From obs: "1-3 mm faceting in front of the Montage. Clear skys and mid 20 temps"
