Gusty winds transporting snow in Taylor Fork on Saturday. Triggered a 4-5 inch deep wind slab that propagated about 50 ft at the top of a north east facing slope at 9,500 ft.

We are grateful for our partnership with the Friends of the Gallatin National Forest Avalanche Center. It is always a good time to get out in the field with our education coordinator, Shannon. Photo: GNFAC

The snow depth was 60-70 cm (2-2.5 feet) at the upper elevations of the Big Springs Loop around the Black Canyon area in Island Park. Photo: GNFAC

Surface hoar and near surface facets are now capped by this weekend's snow. The layers are buried 2-4" deep in the Black Canyon area of Island Park. Photo: GNFAC

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 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.

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