A 100’ wide by 12”-24” deep avalanche was triggered by a skier on a North East aspect of Woody Ridge at 9000’. Skier was carried and partially buried after arresting on a tree. Photo: Anon

A large avalanche failed naturally on January 30th. It broke deep in the snowpack on a layer of weak facets. Photo:L B. Fredlund

From Obs: "Skied up near Big Horn Peak today, around 100cm HS, a bit unsupportable and thin down low. Got lots of whumphs, probably 20+. Saw an avalanche on the west face of Meldrum, looked to be a few days old, but probably R2D2." Photo: S Jonas

A snowmobiler triggered this avalanche on Monday (2/1/2021) at Lionhead. No one was caught. Photo: Anonymous

This small avalanche was below the corner of Lionhead peak. It was one of the smaller slides during the avalanche cycle that occurred 1/29 and 1/30. Photo: GNFAC

The avalanche broke in the new snow, but stepped down into deeper layers (sugary facets) mid-path. This can occur when there are multiple weak layers in the snowpack. Photo: GNFAC

Every path along the shoulder of Targhee Peak (Lionhead area) avalanched naturally during the storm 1/29 and 1/30. Photo: GNFAC

This steep north facing slope avalanched about 3 weeks ago on depth hoar when a snowmobiler triggered it. It got reloaded with new snow and wind drifts and avalanched a second time! Photo: GNFAC

This natural avalanche occured on a NE facing slope at 8600". It was 2' deep, 500' wide and 250' vertical. The avalanche broke on a thin layer of facets during the storm. SS-N-R3-D2-O. Photo: GNFAC

On the north end of Lionhead Ridge is Airplane Bowl. The crown line extends across the entire bowl on the right with a separate avalanche on the left. Photo: GNFAC

Take a close look at the picture and you'll see crowns from the far left to the far right of the photograph. Photo: GNFAC

Many avalanches broke under the new snow and also deeper on facets. These natural slides occurred on 1/29 and 1/30. Photo: GNFAC

South of Livingston (outside our advisory area) new snow fell onto a layer of surface hoar. Skiers observed shooting cracks while touring. Photo: D Britt

Skiers northwest of Cooke City observed many new slab avalanches on all aspects from mid to upper elevations. Some stepped down onto older persistent weak layers. Photo: B. Fredlund

A skier north of Bridger Bowl ski area noted a layer of feathery surface hoar growing in the upper 500 vertical feet to the Ridge. B. Van Wert

There were many loose snow avalanches or sluffs with the 8" of new snow in Hyalite. These avalanches were not breaking as slabs but a thin layer of weak, near-surface facets caused the new snow to slide actively. Photo: N. Salsburg
