Snowmobile triggered slab near Sheep Mtn.

On 3/12/22 near Cooke City we saw many natural and snowmobiler triggered avalanches that broke 6-10" deep. Snow over the past week fell on a hard melt-freeze crust. Last night, 4" of new snow with moderate wind created unstable wind slabs that broke wide on the buried crust. Photo: GNFAC
