I went skate skiing up Sourdough Canyon today. The trail intersects many south and southwest-facing avalanche terrains that generally do not have much snow coverage due to their exposure to the sun. 

However, the snowpack is much deeper than normal in the Gallatin Valley and in the low-elevation mountains around the Valley, and these slopes make me nervous, especially because they would impact a trail that sees heavy use by people who do not intend to expose themselves to avalanches and who are not prepared for avalanche rescue.

Feb 7 We saw a couple storm slabs that broke in today's snow 4-6" deep, 10-30' wide, and we triggered one 3-4" deep wind slab, "remotely", from a few feet back on a small ridgeline. R2-D1. These slabs were very soft, F- to F hard. Photo: GNFAC

At the base of G2 I triggered a 3 inch x 100 foot soft slab. Photo: D Chabot

Most notable test result was ECTP16 down 35 cm on a layer of surface hoar. Photo: E Heiman

Three to four inches of new snow from yesterday sat on top of the dust layer that got deposited across most of the forecast area on Monday and Tuesday. Photo: GNFAC

There was evidence of several R1-2/ D1-2 wind slab avalanches that likely ran this weekend on the east face of Blackmore. Photo: GNFAC

Swift Current lift shut down all day Wednesday 2/5/25 by ski patrol

200ft wide and rather shallow, did not manage to run fully into the apron. 

This was a small remote trigger next to the skin track, about 20 feet wide by 10 feet long.  Photo: K Gordon

I went for a walk up the main fork of hyalite today and observed a very dirty snow surface from the strong SW winds. Photo: Anonymous

A little wind load cornice break, but it broke while I was coming down that track to the right. Photo: S Strenge

This is the N side of scotch bonnet, looks like a big break, didn’t get any closer than this however. Photo: S Strenge

 

N face of crown butte, looks like it slid before the dirt event (we think the end of the storm yesterday/ or last night must have been dirty snow?). Photo: S Strenge

Avalanche east aspect of Henderson. This slid sometime between 11:30 - 12:30 on 2/4/24. Photo: BPG

Avalanche on north aspect of Fisher Mountain. This likely slid sometime between 2/2-2/3. Photo: BPG
