Primary Problem: Persistent Weak Layer
Bottom Line: Unstable snow is widespread across our advisory area. Weak snow at the ground that fell in October and early November has been overloaded by this week’s new snow. Any slope that held snow before last weekend is suspect. If you ride on or beneath steep slopes today, expect to trigger avalanches. Avoid the hazard by sticking to lower angled slopes today and avoiding crossing runout zones beneath steeper slopes.

  • Skier triggered avalanche at the bottom of the 2nd/3rd finger at Bridger Bowl.

  • From obs: "Skinned above alpine lift (just beyond the beacon checker) to get an idea for snowpack depth/ layers. A quick dig revealed a shallow, faceted snowpack!"

  • Shooting cracks on the apron. Shallow and firm but reactive windslab breaking on the faceted layer bellow it. About 10cm of new snow sitting atop the windslab as of this afternoon. Photo: C. Bayles

  • The mountains look good with a fresh coat of paint, but the snow cover remains thin. Photo: GNFAC

  • Skier triggered windslab in the Great One off of Naya Nuki peak, skier was carried 15-20ft before arresting. Slide was triggered roughly halfway down the couloir where the right wall dips away exposing the snow to wind. Hard consolidated snow over facets, roughly 1-1.5 ft thick, ran about 50-100 ft before pouring over the cliff faces below. North- northeast aspect. Photo: J. Alford 11/8/2023
