Big Sky ski patrol triggered these slides with explosives on 11/22 during routine avalanche mitigation work. The avalanches were hard slabs that averaged 12" deep and broke on a weak layer above a crust on top of snow that fell in October. Photo: BSSP

From IG message: "We saw a few decent sized point releases in the same zone on Sunday, 11/20, the day after the wind slab. All occurred on SW aspect within approx 15 min at 2:30. The air temp rose noteably shortly before and the sun was baking the SW aspect. Wind slab from 11/19 is on the far right, two point releases on the left". Photo: M. Zenker

Went touring within Bridger Bowl's currently closed boundaries yesterday. The week of cold temperatures and lack of precip has done a number on the snow in terms of quality. Below the tops of PK and Alpine lift, all aspects have been wind affected. There is very little fresh snow available for transport anymore (at least below the ridge). I dug a little pit going up towards the fingers from PK. HS was 43cm. The base layer had a sugary, square-ish look to it, likely faceting rounds. The temperatures yesterday were mild and sunny and the winds were low.
Loud pow, obvious near surface faceting on most slopes, thin breakable sun crust on S aspects, wind affected on unprotected NW aspects at ridge line, ECTX x2, lots of deadfall, still too thin in many places for enjoyable skiing
