4 Past 48 hours pt 9885 Prairie Creek E/W fork divide
E 9500 		D1.5 U N-Natural
Several D1-D1.5 avalanches in the bowl on the divide between W and E fork of Prairie creek
1 Mushroom Ridge SE face, 9500' to 9000'
9500 		D2 N-Natural Looks like a cornice drop into a gut on Mushroom, and two (or potentially one that spans around the trees between the higher crowns) further in along the summit ridge of Mushroom. See additional picture in media above.
Natural activity on Mushroom Ridge
1 Cabin Peak, Sawtooths
E 9500 		D3 N-Natural One very large avalanche and a few smaller but still significant pockets that also released. Looks like it has stepped down deeper in places, 12/7?
Very large avalanche on Cabin Peak in the Sawtooths

Very hard to say from pictures, but it looks like the avalanches in the Boulders and Smokies have not stepped down deeper and might just be the snow since 1/10 or potentially 12/31.
The one on Cabin Peak looks to have ripped deeper into the snowpack, maybe down to 12/7?
