Bottom Line: Wind slabs are possible to trigger, especially where they formed on top of buried weak layers. Snow and wind this afternoon may create fresh, unstable wind slabs. Be cautious of drifts of snow on steep slopes and dig down to check for buried weak layers before riding steep slopes.
Primary Problem: Wind-Drifted Snow

  • At 1:30pm on 11/23 I intentionally triggered a fresh drift of snow in a narrow avalanche path along the edge of the north bowl at Bridger. Northeast aspect at 7,600’ elevation. The crown was 6-8” deep consisting of snow that fell today, 20’ wide and ran 250’ vertical. SS-ASc-R2-D1.5-I. Photo: GNFAC

  • Big Sky ski patrol triggered these slides with explosives on 11/22 during routine avalanche mitigation work. The avalanches were hard slabs that averaged 12" deep and broke on a weak layer above a crust on top of snow that fell in October. Photo: BSSP

  • An observer reported "A number of Avalanche Crowns on an east aspect at 9500 ft." in Tepee Basin.

  • From obs: "Skied Hyalite Peak today and found a wind slab ~10cm deep. Ski cut a small cornice below the main face and broke a small slide that carried ~20’ with little energy with a ~25’ wide crown" Photo: C. Crowe

  • From obs 11/12/22: "Looks like this could be a problem when buried."

  • Evidence of wind-loading creating the conditions for avalanches in the Bridger Range. Cracking is an indicator of instability. The observer noted this was "Nothing consequential," but this shows that unstable drifts are forming. They will be more consequential where there is more snow and as the wind creates larger drifts.

Your field observations are hugely helpful as we build a picture of snowpack stability. Let us know if it was a beautiful day or snowy, deep powder, avalanches seen or just boring riding. Submit your observations on our new page or read them all here.
