20-21

From obs. on 12/2/2020: "...a skier triggered avalanche... at Bridger Bowl (Schlasmans Lift) from this afternoon. I was skinning up the N subridge to the lookers right of the lift and some skiers above me triggered a wind slab on faceted snow that came down almost right on top of me. I had to run on my skins to get out of the way. I dug 3 pits yesterday and got ect1 every time so was up skiing and skinning conservatively which allowed me to get out of the way of the slide in time to avoid being caught and most likely buried. The toe of the slide was all of 6’ deep....

"...There is about a foot of fresh sitting on top of faceted crust that is sitting on top of more facets and another crust, and obvious red flags from wind affect (big ripples, obviously wind loaded slopes, obvious slabs forming that you can break through with your skis)..."

Skiers triggered small loose snow avalanches (sluffs) of cohesionless facets in middle/beehive Basins on 11/30. These sluffs were 1ft to 18 inches deep and involved the whole, thin, snowpack.

From skiers at Bridger Bowl: "Small avalanche running from Northwest Passage about 1/3rd of the way down the Apron. 20ft wide, unknown length or start location. R1 D1 involving primarily new snow with minor entrainment of old snow."

Skiers in the Northern Bridgers also reported a small slab avalanche in Frazier Basin.
