Primary Problem: Persistent Weak Layer
Bottom Line: Yesterday was the third day in a row with reports of avalanches and widespread collapsing/whumphing of the snowpack. Across our forecast area the snowpack is unstable, and a person can easily trigger a dangerous avalanche. Slopes that had snow on the ground prior to last week’s new snow are the most dangerous, especially where recent strong winds also drifted snow into thicker slabs. Now is not the time to travel on or underneath slopes steeper than 30 degrees.

  • 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
