Northern Gallatin

We found 80 cm (2+ feet) of snow on a NE facing slope at 8,000 feet outside Bridger Bowl's Boundaries. The snow was supportable with a weak layer at the blue card. Faceted, weak, sugary snow is the layer of concern, but it was not that bad...yet. We'll be watching to see if it gets weaker. Photo: GNFAC

Monday night's new snow formed wind slabs from the strong wind on Tuesday. We are finding these throughout southwest Montana. Photo: D. Britt

New snow was blown into thick drifts that can be triggered by skiers or riders. Cracking like this is a sign that drifts are unstable and could slide on steeper slopes. Photo: GNFAC

This post and picture was on the FB ice climbers page. This is from Comet Alley, a steep gully off the East Fork Road:

Today we found that this gully has some significant loading. We triggered a few wind slab slides on the approach. We managed to get a quick lap on the route and got out before it got loaded more. TBH with more unconsolidated snow I’d reconsider going there.

From email (12/5/21) : "Small avalanche triggered while approaching ice climb in East fork of Hyalite basin. 

Another D1 natural avalanche was observed later in the day similar aspect/elevation
