Surface hoar in Taylor Fork
Trip Planning for Southern Madison
Primary Problem: Wind Slab
Bottom Line: Human-triggered avalanches in fresh drifts of wind-loaded snow near ridgelines and in steep gullies are possible. With storm totals ranging from 2-4”, wind slabs will be 4-8” thick and relatively small. Seek out slopes sheltered from recent wind-loading where human-triggered avalanches are unlikely. Carry rescue equipment, dig to assess for instability related to buried weak layers before committing to steep slopes and travel one at a time with someone in safe position for rescue when traveling in and around avalanche terrain.Past 5 Days

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.
