Observation Details

Observation Date:
December 2, 2022
Submitted:
December 2, 2022
Observer:
SAC - Jon Preuss
Zone or Region:
Soldier and Wood River Valley Mtns
Location:
Mid Valley roadside tour and Baldy Inbounds

Signs of Unstable Snow

Recent Avalanches? 
Yes
Cracking? 
Isolated
Collapsing? 
Widespread
I got to ski one run down Baldy and had multiple collapses in the glades. It was pretty surprising, because they were "east coast tight" trees.

Snow Stability

Stability Rating: 
Fair
Confidence in Rating: 
High
Stability Trend: 
Steady

Bottom Line

Today I observed a widespread natural cycle mostly on northern aspects. Areas that received more snow and wind had avalanches that were big enough to bury a person. There was evidence of a weak snowpack in this forecast zone with remote triggering likely. I cautiously chose the terrain I was skiing today even when inbounds.

1 Sun Peak

r-Remote
Group likely remote triggered while skinning up the shoulder of Sun Peak. It is unclear if the lower right avalanche occurred today or at the tail end of the storm. The skin track went on top of the bed surface.
2 Triple Peaks

D2 SS I-New/Old Interface 2' N-Natural Crisp looking crown, likely at the tail end of the storm. Another crown to the east of this location.

Other Observed Avalanches:
Starweather: 1 naturals - D1.5 5900' NE
Greenhorn: 6 naturals - D1 5800-6000' N
KOA Chutes: 5 naturals - D1.5 NE
Prospect Hill: 1 natural D1 W

Morgan's Ridge: 7 naturals - D1.5 6600-7000' NW
Warm Springs: over 17 - D1-D2 N/NW (3 spots hit the road with debris yesterday morning) Crown locations varied from ridgeline to mid and lower path

*All crowns were generally 1-2' deep, unless another thickness is mentioned.

Snowpack Observations

Hand pit in gladed area showed 35-40cm slab on top of 11/27 interface with facets below it.

Terrain Use

Traveling solo, but closed all avalanche terrain for the day. Continued my assessment mindset.
