"At 9410ft, NNW aspect, 10 degree slope, we found HS 75cm. The general structure seems right side up. There are facets at the bottom 20cm or so, but they are wet, and seem to be rounding. An ECT gave us ECTN20 at 40cm down." Photo: N. Mattes
Trip Planning for Cooke City Area
Primary Problem: Wind-Drifted Snow
Bottom Line: Human-triggered avalanches are possible due to recent snowfall and fresh drifts of wind-loaded snow. Avoid fresh wind slabs on steep slopes and look for signs of instability, including shooting cracks and recent avalanches. Dig and test the snowpack to evaluate for instability related to sugary, weak layers. Watch for wet loose avalanches on steep slopes that receive direct sunlight.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 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.

The Last Word
Bridger Bowl has backcountry conditions, and there are no ski patrol services. While they set up for the season, please steer clear of snowmaking equipment, chairlifts, and snowmobiles and respect posted signage.
