From email (1/6/22): "Skied the Throne today. New snow instabilities. Higher density snow falling on colder snow. Saw a hand full of naturals all running on the new snow old snow interface."

Behind the sledders are deep piles of debris from an avalanche cycle a week ago in the Mt. Jefferson area near Island Park. Photo: GNFAC

This avalanche broke wide in a northerly facing bowl off Lionhead Ridge. It looks to have broken a foot or less deep. The propogation indicates a uniform weak layer, likely near-surface facets or surface hoar. Photo: B. Fuglie

Snomobilers observed this natural avalanche on a NE aspect on Sheep Mountain on 1/1/22. It appeared to be more than 48 hours old. Photo: J. Fritz

From obs: 01/01/22: "Saw a small slide come off the ridge. We dug a pit and the wind slab was 8 inches to a foot and a half. During our snow tests it consistently broke on the week layer around a foot deep." Photo: B. Paulson

From obs 1/1/22: "While skinning towards the ramp we witnessed what looked like a natural slide that started right around Pete’s Pinnacle which ran down along the boundary line about 1000 feet. Unknown trigger."

Strong ridgetop winds transported snow onto Saddle Peak creating unstable slabs on January 1st. Photo: GNFAC

Strong winds on 1/1/2022 formed fresh, soft drifts. These drifts broke and cracked easily, and slid on steep slopes. Photo: GNFAC

We saw this natural avalanche on the north summit of Saddle Peak on 1/1/2022. It is one of at least 4 natural avalanches that broke on wind-loaded slopes on Saddle Peak in the past 3-4 days. Recent snow and wind formed slabs over weak facets which makes large avalanches possible to trigger.
