Bottom Line: A foot of new snow fell onto a weak snowpack over the last two days. A widespread weak layer beneath the new snow will make avalanches break easily. Human triggered avalanches are likely on all slopes, especially wind loaded ones. The avalanche hazard is very serious today and cautious route finding is essential for safe travel.

  • 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

  • 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.
