Ski patrol reported this large natural slide on 2/7/21. Photo taken 2/10/21: BBSP
From email: "Skied the ramp outside of Bridger Bowl today, saw these small NE facing crowns at 8350'. We also experienced localized cracking while skinning at the density change interface of the new and "old" snow (8-12" at this elevation by 4pm). No other observed avalanches, no other cracking and no collapsing."

From Obs: "Skiers traveling on South facing slope at 9,100ft elevation ascending Miller Trees remote triggered from skin track (second lap) a wind slab slide on a steeper East facing slope that slid to gully floor and out to Sheep Creek. Westerly wind was blowing with gusts carrying snow to load the east-facing side of the gully. Crown was approximately 4ft at the crest of the gully’s slope. Cracking visible in the photo from skin track traveled up to crown 50yrds away. Pit dug at similar elevation on South facing slope yielded slight cracking within the storm slab but no propagation (ECT16N)."

We saw widespread cracking on several steep slopes on Mount Ellis. 20"+ of new snow loaded a weak snowpack.
