On 2/9/20 We saw deep avalanche crowns on the west side of the Bridger Range in almost every drainage from Saddle Peak to Ross Peak. These broke at various times throughout the recent storm that deposited 4 feet of snow with over 4" of SWE in the last week. Photo: S. Cottom

A snowmobiler found very touchy conditions in Portal Creek. The new snow easily avalanched on road cuts so they went home. Photo: @jakehopfinger

We saw a group of six snowmobilers who said they triggered these slides in McAtee Basin on the left side of the meadow on Saturday, Feb 8. I didn't see tracks up on the hill or sidehill tracks so they may have triggered the slope from the flats below. The debris runs all the way to bottom of the hill. Photo: K Peaslee

A natural 4-8' deep slab avalanche broke on Saddle Peak within the last couple days (2/6 or 2/7) during the current storm. The mountains received 3-5 feet of snow equal to 3-5" of SWE over the last week with more snow in the forecast. Photo: GNFAC

A natural 4-8' deep slab avalanche broke on Saddle Peak within the last couple days (2/6 or 2/7) during the current storm. Huge avalanches like this are likely and can be triggered by a human for the next couple days. The mountains received 3-5 feet of snow equal to 3-5" of SWE over the last week with more snow in the forecast. This heavy load is overloading a fragile snowpack, especially on wind loaded slopes. Travel conservatively. Photo: GNFAC

"Noted two SS-D1.5/2 naturals (presuming based on lack of any sort of tracks) on Wheeler, typical spots for these conditions, both SE aspect around 8000'." Photo: G. Antoniolli

"Noted several avalanches (NW aspect ~ 8800') off of Elephant that traveled quite far into the trees where the summer trail typically runs, all appear to be new snow, D1- D2 in size, average 2' crowns, running on old/new interface from  Feb 2. They appear to have run midstorm, sometime yesterday (photos 1,2,3).  Above 9000', W Winds were crafting fresh wind slabs that were most reactive on a midstorm crystal/density change that buried a layer of stellars ~ 1' deep in shallower spots,  topped with denser snow."

"Natural avalanche. North facing slope. Around half mile wide. Photos don't show half of the slide. Broke on the ground facets. Crown was between 3 and 15 feet deep. We didn't get a photo of the deepest crown. Ripped trees out around 5" diameter." Photo: Reed Malmstrom

On private property, this small child triggered a slide and climbed out of the debris, not buried. A very close call! On the heels of this large snowstorm there are possibilities of children getting caught on road cuts or any open hill!  Photo: Anonymous

We saw these avalanches on the afternoon of 2/7/2020. They broke in the storm snow about 3 feet deep. North of Bridger Bowl on an East-southeast aspect at 7,500'. Probably occurred within the last 24 hrs. Photo: GNFAC
