Skiers south of Cooke City observed a recent wind slab avalanche that happened on east-facing terrain near Republic Creek. This avalanche likely happened in the last 24 hours. Photo: G. Roe

Riders N. of Cooke City saw a recent avalanche north of Scotch Bonnet that broke 100' and several feet deep. Photo: A. Marienthal

A group reported many avalanches on the northern aspect of Miller Ridge. Some had filled back in from wind drifted snow. Other crowns were crisp. Photo: J. Padilla

Skiers on West Woody Ridge triggered a wind-slab avalanche that failed 1 foot deep and 40 feet wide. The avalanche ran 300 feet. Photo: N. Dogg

On 2/24/24: We saw a slide on the north end of Sheep Mtn. on a slope above the steep chute where people climb out of Goose Creek. This slide had not been reported previously and looked similar in age to the two triggered yesterday, so maybe broke naturally or human-triggered in last 24 hours. It broke near a scoured north facing ridgeline, 1-1.5' deep, 175' wide. HS-R3-D2-O. Photo: GNFAC

On 2/24/23 we got a pretty good look at the slides on Fisher Mtn. that were triggered yesterday. They appeared 2-3 feet deep, and the debris was very hard. Crowns were already at least half drifted in. Photo: GNFAC

Riders on 02/23/2024 saw an avalanche that appeared to of broken naturally. However, a rider on 02/23/2024 triggered a steep slope around the corner and could likely have remotely triggered this avalanche as well. Photo: D.Shelley

A snowmobiler triggered a large avalanche on the north side of Fisher Mountain on 02/23/2024. He was caught and carried downhill but luckily was not buried. Photo: D.Shelley

From obs: "Photo of an avalanche observed yesterday (2/21) on the SW face of Sawtooth Mountain at about 10,600’. Looks to be a few days old, but hard to tell since all skier traffic from the weekend has been erased with Tuesday’s wind/precip. If you look closely, you can see the crown extends across the entire face." Photo: A. Joy

Riders on 02/18/2024 saw an avalanche that was triggered a few days prior on 02/16/2024. 

Riders saw recently triggered slides that were likely triggered by snowmobilers on 02/17/2024. 

A rider on 02/18/2024 saw a recent avalanche that was likely remotely triggered by a snowmobiler the day before on 02/17/2024. 

Close to the ridge and the starting zones of nearby avalanche paths, we triggered a large collapse that sent shooting cracks out a couple hundred feet. If the slope had been any steeper, we would have triggered an avalanche. Photo: GNFAC

From email: "A large avalanche. crown propogated through the cliffs and looked to be about 200' wide and 1 1/2-2 ft. deep. Debris was no longer visible so I suspect this ran sometime during or shortly after the storm. (02/15)." Photo: G. Roe
