Our results were CT17 SPQ2 and ECTP26 SCQ1. Bother failures during tests were on the layer of facets and on the CT and ECT our columns easily separated from the facet layer after failure. Photo: C Culver 

On Jan 12, we saw 4-5 avalanche crowns that were up to a week old, some had been reported and a few we had not heard of. Two were ~2' deep on less wind affected slopes lower down in the trees, but probably had some previous wind-loading. Photo: GNFAC

On Jan 12 We saw 4-5 avalanche crowns that were up to a week old, some had been reported and a few we had not heard of. The pictured one was a 3-4'+thick slab on a rocky heavily wind-loaded slope off Lionhead ridge. Photo: GNFAC

A wind slab avalanche was seen just below Two Top. This appeared to be a natural slide although tracks can be seen above and to the left of the crown. This was on a northeast facing slope that was wind loaded. The avalanche appeared to be fresh after recent snow. Photo: C Barnhart

Probably already reported...but touchy storm slabs on Mt Blackmore. Attached is a photo of a natural from the approach, at the switchbacks to the upper basin.

Jan 10, We dug a pit on Henderson Bench on a northeast facing slope, and one on Scotch Bonnet on a south facing slope (pictured). Both showed a 4' thick strong slab on weaker, faceted snow at the base. The weak layers are not terribly weak and didn't produce concerning test scores, so they may get better when they get a break from snowfall and wind-loading, but for now recent avalanches show these layers are weak enough and will produce more big avalanches as snowfall and wind continue.

We looked at two 4-6' deep persistent slab avalanches that were reported yesterday on the east side of Henderson Mtn., which likely happened yesterday (Jan 9). Wind-loading was the likely trigger. There were not tracks near the larger one above the bench, where riders could easily get to, but they could have been filled in. The other slide was below the highest point below a cornice and likely natural. Both looked like they broke on facets at the bottom of the snowpack. Photo: GNFAC

Wind slab Blackmore south bowl - 10 Jan 2025

Wind slab along Blackmore trail. Good clue before we got above treeline where more wind was blowing and moving snow

We triggered this wind slab by triggering a smaller one above it while descending the NE ridge of Blackmore. 
~10-12" deep and 25' wide

Big wind slab on N face of Mt Blackmore. We watched it cut loose at 14:25 from cornice fall.

Good news is that it didn't trigger a deeper slide.

On 01/08 my partner and I skied into Frazier basin in the northern Bridgers, we skied the love chutes east down and overall the descent was pretty wind hammered from a downward wind. Once at the lake we took the Frazier return route where we found much better ski conditions in the corridor and decided to lap some of the features. We ended up triggering a small wind slab at around 8k on a NE aspect that broke about a foot deep and ran about 25 yards. Very dense wind slabs were forming on a lot of the aspects getting out of Frazier and we opted to not test our luck any further for the day.

On Jan 9 We saw many avalanches of various types and ages. Some occurred today and within the last 24 hours and some were up to a week old. Avalanche types ranged from 3-6' deep and broke on weak layers near the bottom of the snowpack to shallow soft, fresh wind slabs. Photo: GNFAC

On Jan. 9 we rode away from our snowpit on Mt. Abundance we saw a fresh 3'deep x 10' wide slide that we might have remote triggered from the flat ridge above.
