From obs 3/12/22: "Upon descending a ~35 degree slope, I (the snowboarder) kicked loose a wind slab that propagated 100 feet wide, 8 inch deep (max, 4 inches at edges) wind slab that traveled approximately 300 feet (entire slope over 30 degrees) before settling in 2 debris fields, each about 30’ wide and with a maximum of 2’ depth. No one was swept by the debris/buried/injured."

On 3/12/22. We saw 5+ avalanche crowns that appeared to have broke naturally, and got reports of a few others. All were 6-10" deep, recent wind-drifted snow failing on a hard melt-freeze crust.
Skiers remote triggered a soft slab on a S facing slope. Broke about 8 inches deep on the mfc

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
