Wind slab avalanche on Lionhead Ridge. Approximately 50 ft wide and ran 200 vertical feet. Looks to have gouged down into lower layers below the rocks. 2/3/22. Photo: GNFAC

From Obs: "A group of six of us were sled-skiing in Goose Creek today and I triggered a soft-slab avalanche on a wind loaded slope. We had skied 3-4 runs in the trees before lunch and had seen little to no signs of instability. We'd come to this area three days earlier to dig pits and found the PWL noted in avalanche report for Cooke City. There was an older crown about ~5 days old clearly visible in the bowl we decided to ski after lunch. I dropped in and skied off a cliff just to lookers left of the crown "triangle" and when I landed I triggered the avalanche. It broke roughly 60 feet wide with a crown depth of 12-16". I was able to self arrest less than 20 seconds after the avalanche started and the snow slid around me. I lost a ski but was otherwise unharmed. I also had an airbag but did not need to pull it."

From Obs: "With a ski cut, I released a very small slab that entrained a decent about of snow by the time it stopped ~600 vert. feet lower. It was the thin wind slab sliding on softer snow underneath." Photo: W Gober

From obs. 2/27/22: "... on our way up Flanders. Near ridge line there’s a 3-4”, dense wind slab that was quite touchy. I chucked a basketball size piece of cornice onto a small test slope and observed it collapse and crack." Photo: S. Gill

From message 2/27/22: "Skier triggered yesterday in a northeast wind loaded pocket on baldy in S Bridgers. About 6 inches deep and 100ft wide.
Quite a bit of shooting and cracking elsewhere at lower elevations. Felt wind loaded just about everywhere after those east winds." Photo: J. Keogh

From obs 2/27/22: "Shooting cracks in a thin wind slab on a ridge crest. The slab was small but the collapse was abrupt and propagated 20 feet." Photo: J. Taylor

From obs 2/27/22: "Skied Flanders mountain today. Dug a snowpit on a SE facing 24 deg slope at 9700 feet. ECTN24 30cm down on a layer of facets just under an ice crust. Snow above the ice crust was 4F- at most and not hard enough for anything to propagate. Winds were moderate and gusty, transporting a decent amount of snow but not really forming any slabs other than at the ridgeline. I triggered a shallow 2-3cm deep windslab about 20 feet wide just below the ridgeline. I was not on a steep slope, so it barely moved.... didn't see any other signs of instability." Photo: M. Lavery

We saw this avalanche the afternoon of 2/27/22, on a north-northwest facing slope on Sheep Mtn. near Cooke City. It appeared less than 24 hours old and likely snowmobile triggered. Photo: GNFAC

This slide was triggered by a sledder on 2/26/22 around 1pm near Goose Creek outside Cooke City.

From obs. 2/26/22: "This is a slide that was triggered today at Mt. Blackmore. Nobody was hurt...”

From email 2/26/22: "Skiing in the Northern Bridgers today, one skier in our party of three triggered an avalanche in October bowl. The slide was approximately 40 yds wide and ran around 150 yds. The skier was carried approximately 100 yds, but was not buried and sustained no injuries. Neither of the other members of our party were in the slide path when it occurred... photo shows the slide from the bottom and the approximate path the skier was on when he triggered the slide."
