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

Driving up Bridger Canyon this morning, we noted several natural avalanches in wind loaded terrain on Saddle Peak, the Football Field, and in Mundy’s Bowl. All The avalanches seems to be a similar wind slab problem. They broke just below the cornice line. Photo: GNFAC

From obs: "I dug a quick pit just off from the ridge and noted an HS of 55cm with an 3cm decomposing crust about 29cm up from the ground. Snowpack ranged from fist hardness down to 1 finger at the base. And though the grains at the ground had some edges and corners, I did not note truly faceted snow at the base."

Wind was ripping on the ridge and creating hard wind slabs 3-6” in depth. Photo: C. Avis

The snowpack remains thin (20-25 inches of mostly unconsolidated base) and there were plenty of rocks and stumps to hit, but coverage was better than I expected (and probably better than most of December 2023). Photo: GNFAC
