Bottom Line: Once again, Cooke City is a catcher’s mitt. A strong storm from the southwest has dropped 17” of new snow with strong wind. Most avalanches happen during a storm and large storms can produce large avalanches. Today is a day to be cautious and stay out of avalanche terrain and away from the flats at the bottom of big slopes (aka. runout zones).

From email: "We noted one recent slab avalanche today on a NE aspect of Mt. Henderson, around 10,000.  We were skiing nearby on Nov. 11-12 and did not notice this slide, but that may have simply missed it (that slope becomes shaded by about noon this time of year and there was lots of wind affected snow in that area.)"

  • From obs: "Well developed surface hoar was widespread this morning near Cooke City (11/25). The strong sun burned it off on aspects that received sun, but it was preserved in shaded areas." Photo: N. Salsburg

  • 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

  • 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.
