Near and Below treeline action in SE Mtns.

CBACCBAC Observations

Date of Observation: 01/05/2023
Name: Zach Guy

Zone: Southeast Mountains
Route Description: Viewed from Mt. CB looking east towards Pearl Pass, Doubletop, etc, looking at the western half of the compass.

Observed avalanche activity: Yes
Avalanches: Lots of action above treeline that looks fresh, likely from the 1/3-1/4 cycle, generally on cross-drifted features from the NW winds, D2 in size. Also a lot of activity at all elevations that looks a bit older, likely from the 12/31-1/1 cycle. Only documenting the larger slides (D2), plenty of smaller ones too.

Climax Chutes details

CBACCBAC Observations

Date of Observation: 01/05/2023
Name: Kevin Krill

Zone: Southeast Mountains
Route Description: Below Climax Chutes

Observed avalanche activity: Yes
Avalanches: I drove over the pile on Mike’s and then around the toe of the debris. Guessing 15-20′ deep for 200 yards. Could be one of the biggest debris piles I’ve driven over in my tenure. The three main paths and all of the smaller ones on lookers right cleaned out. The two on the lookers left did not go.

Name: Irwin Guides

Zone: Northwest Mountains
Route Description: Terrain near Irwin Cat Ski.

Observed avalanche activity: Yes
Avalanches: Bender failed on 10 cm’s of small grain facets on the ground. The crown was 4′ at
it’s apex.  SS-N-R3-D2.5-O/G Large Natural that most likely ran last night avg. 1m crown started below thin line and connected over to SS L. 11,600K S-SSE aspect 90 cm X 150m X 80m

Numerous naturals size 1-2 UUWW,

Red Lady Bowl Wall to Wall

CBACCBAC Observations

Date of Observation: 01/04/2023
Name: Eric Murrow

Zone: Southeast Mountains
Route Description: Standard skin track up Mount Emmons to Red Lady Bowl and descent down Glades.

Observed avalanche activity: Yes
Avalanches: A very large avalanche in Red Lady Bowl that broke full-width wrapping from the skin track ridgeline all the way across bowl to saddle with Red Racoon. Crown up to 8 feet thick. With just a skiff of new snow on the bed surface.  The debris was hard to see in the poor vis, but I estimate it only ran half of the potential track.
Weather: Mostly cloudy skies with light snow, generally light wind with moderate gusts occasionally transporting snow.
Snowpack: I dug a profile on a near treeline slope with a depth of 150cm that produced an ECTP 30 and PST end 45/100 on basal facets. I found Surface Hoar at this location sitting above the 12/20 crust that produced PST end 30/100. While exiting the profile site, our group collapsed the slope. Slabs near the treeline were around a meter thick with 40cm being 1finger hard.
