Submitted:
January 8, 2022
Observer:
SAC - Chris Lundy
Zone or Region:
Sawtooth and Western Smoky Mtns
Location:
Glassing from Stanley to Galena Overlook

Signs of Unstable Snow

Recent Avalanches? 
Yes
Cracking? 
None Experienced
Collapsing? 
None Experienced
Cracking/collapsing N/A - I was roadside.

Bottom Line

Glassed from Stanley to the Galena Overlook, so primarily viewing the Sawtooths and the drainages behind Smiley Creek. I was able to look up Pole Cr somewhat, but the Smoky Crest (Titus - Saviers) was obscured by a cloud.

I saw evidence of a storm-related avalanche cycle in the Sawtooths and the Western Smokys near Smiley Cr. I did not observe any deep persistent slab avalanches breaking on older weak layers.

Weather Summary

Cloud Cover:
Partly Cloudy

It was mostly cloudy this morning in Stanley, but the clouds dissipated mid-morning and skies were partly cloudy. Looking from Stanley, there appeared to be more clouds towards Banner Summit, even midday.

Avalanche that ran near the end of the storm behind Horton Peak in the Pole Creek drainage. Slab appears to have failed at the old/new interface, or possibly on layers that formed in December. 10,000', SW.

D2 SS-Soft Slab N-Natural
Evidence of multiple avalanches on McDonald Peak that ran at different points during the storm. The most recent ones are in the upper right of the photo. These avalanches likely involved new and windblown snow. 9700', E.

D2 SS-Soft Slab N-Natural
Avalanche in the northern Sawtooths that released near the end of the storm. It looks to have involved the storm snow, and the slope was likely loaded by wind and spindrift spilling down cliffs.

There was evidence of a storm-related avalanche cycle in the Sawtooths and the Western Smokys near Smiley Cr. I saw more avalanches in the Sawtooths, but that may be because I had a better view of them or possibly the steeper terrain was more conducive.

Most avalanches ran early or mid-storm, as evidenced by barely visible crowns and debris. There were a handful of fresher slides that ran towards the end of the storm. The details on most slides are obscured by storm snow, but none appeared to break very deep and they generally appeared to be failing within the storm snow or at the old/new (1/3) interface.

I did not observe any slides that broke on 12/11. There did not appear to be avalanches (with the possible exception of the Pole Cr slide) that broke on the 12/19-21 layers, although this is less certain.
