Bottom Line: Strong winds will return midweek, drifting soft snow into unstable stabs. The better coverage found on wind-drifted slopes may entice us, but this is where avalanches are most likely to occur. Carefully evaluate snowpack stability and the consequences of getting caught in an avalanche with sharp rocks just inches below you.
Primary Problem: Wind-Drifted Snow

Snow Observations- Centennial Range & Lionhead

Centennial Range
Sawtelle Peak
Sawtelle Peak Snowpack

I drove up the Sawtelle Peak road and dug a pit at the snow marker at 8,800'. There was 1.5 feet (60 cm) of snow on the ground. Around 7,000' the snow was on all aspects, but below that there were melted patches. The snow was supportable and there was no cracking or collapsing. A layer of weak, sugary snow 1 foot off the ground broke clean in stability tests (ECTP 18, 21) and I anticipate this layer will get weaker with time. On the surface there is a thin layer of snow that is faceting and getting weaker. Photos and snowpit are on this page.

From obs. 11/10:  "Fitness skinning around Bridger Bowl yesterday and noticed a fairly large, new avalanche on the east face of the North peak of Saddle. Maybe 100 feet below the ridge, about 100 wide at the crown, ran thru the rock bands but not over the cliff. Was taken back by the clean propagation." -Albert

  • Skiers on Mount Blackmore observed cracking within the freshly wind-loaded snow on a southeast-facing slope just below the ridge (11/24/21). Photo: J Schack

  • The snow was breaking 1 foot off the ground in the layer at the blue crystal card. Weak, sugary snow broke and propagated in the extended column test with 18 and 21 taps. We anticipate this weakness to get worse in the coming weeks. Photo: GNFAC

  • There was almost 2 feet of snow (60 cm) at 8800' on NE aspect of Sawtelle Peak. Weak snow (facets) is forming a foot off the ground and were breaking consistently in stability tests. Photo: GNFAC

  • Snowcover on Lionhead ridge begins at about 7,000' in elevation on 11/16. Snowmobiling or skiing from Targhee Pass looks very thin and patchy. Photo: GNFAC

  • Taken on 11/16, consistent snow on all aspects begins around 7,000 feet. 1.5-2 feet of snow is found above 8.500'. Photo: GNFAC

  • From e-mail 11/7/21: "...Once in airplane bowl we saw multiple large slides that ran last night, syn-storm. Most of which came down from the East face of Sac. A few 200-300’ wide and running the length of the bowl.,,, attached is a grainy cell phone pic of the slides in Airplane Bowl." -Anonymous.

  • From email 11/4/21: "...noticed two small wet loose avalanches in the east facing bowl between Pomp and Hardscrabble Peaks." Photo: H. Darby
