Date of Observation: 01/03/2023

Zone: Northwest Mountains
Route Description: Flat, up and then down on NE aspect below treeline on the border of the NW and SE forecast zones.

Observed avalanche activity: Yes
Avalanches: Pockets the Clown had a couple of tricks up his sleeve, actually in his pant leg, as he shook some treats out of his pockets on a steeper roll at the bottom when skied.
Weather: calm in the trees, windy transporting snow on the ridge to add a little nice nice for the shred.
Snowpack: Ummm… good for skiing 30-degree slopes and shallower. 14″ of goodness on top of denser snow.

Route Description: Broken sled retrieval mission out Washington Gulch to Elkton

Observed avalanche activity: Yes
Avalanches: Ski triggered a pair of small slabs in the new snow on a drifted rollover, about 12” thick. Vis was too poor to see much avalanche terrain.
Weather: Snowing heavily through most of the day. Elkton had about 14” of fluffy snow by midday. Coneys area had about 8” to 10”. Light to moderate winds near treeline with periods of significant blowing snow.
Snowpack: Stability test below treeline near the boundary of our two forecast zones produced hard, propagating results in depth hoar (F) under a 120 cm soft slab.

Zone: Southeast Mountains
Route Description: South side of Mt. Crested Butte

Observed avalanche activity: Yes
Avalanches: Buckhorn couloir. Looked like it originated in the trees and came down. Hard to say if p slab or storm snow.

Route Description: Gothic

Observed avalanche activity: Yes
Avalanches: Widespread slide activity in this area though except for very steep areas on Gothic most slides were from the new snow and did not carry far, and all small except one moderate one off Gothic. This new snow overnight should not affect much as it is light and not all that much of it.
Weather: Only very light scattered snow Monday until after dark, then it picked up towards sunrise with 4½” new and water a light 0.26″ with little wind and even a bit of clearing Monday afternoon. Currently 48″ on the ground- winters deepest with light to moderate snow and no wind and no visibility.

Name: Zach Kinler

Zone: Southeast Mountains
Route Description: Dog walk through town.

Observed avalanche activity: Yes
Avalanches: A good number of large natural avalanches on South and West aspects from the recent cycle. Hard to tell exactly where in the snowpack they broke but several were widely propagating with crowns several feet deep suggesting they broke on weak layers within the snowpack. Some crowns looked quite fresh likely breaking within the last 24 hours while others likely broke earlier in the cycle.
Weather: Partly cloudy skies, light westerly winds, cool temps.

Observed avalanche activity: Yes
Avalanches: A few more persistent slabs that ran over the weekend, up to D2.5. See photos and details below.

Name: Zach Guy

Zone: Northwest Mountains
Route Description: Traveled on various aspects off of Elkton Knob, most commonly on west and southwest below treeline.

Observed avalanche activity: Yes
Avalanches: The Elkton area saw a decent D2 cycle over the weekend on many steep slopes, various aspects. Soft slabs were generally 2 to 3 feet thick, failing on mid-December facets. In contrast, the Purple Palace area appeared to be relatively quiet during the cycle, perhaps because of Arctic Blast wind effects on the weak layer there. I stomped around on top of a couple of small, steep slopes and triggered one persistent slab that was 3 feet thick (4F) over fist hard 1mm facets on a west facing slope. There was also evidence of avalanche activity earlier in the storm on Baldy, Purple Ridge, and Schuylkill Ridge. Light was too flat to see much else.
Weather: Light snow showers on and off through the day, with bouts of sunshine too. Light to moderate ridgetop winds with blowing snow off of Mt. Baldy.
Snowpack: Fairly quiet while breaking trail and skinning. We got one collapse and chatted with another group in the same area that got several large collapses and shooting cracks. Slabs are consolidating and ski pen is now ankle deep, making for good turns on the low angle.

Zone: Northwest Mountains
Route Description: Kebler Pass area. All aspects. Up to 10,700ft.

Observed avalanche activity: Yes
Avalanches: Several very small storm slabs. 1 to 2″ thick. Some releasing naturally and some human triggered, only on the steepest slopes near or above 40 degrees.

Weather: Overcast, calm wind. heavy snowfall started around 11am and lasted for about 1 or 1.5 hours. The sun started poking through a few times around mid-day or early afternoon on the way home.

Snowpack: Plenty of test slopes around 35 degrees on all aspects and some much steeper. Most slopes were 100ft vertical or less. Some were a couple of hundred vertical feet. The PSa problem presented no obvious signs of instability as has been the case recently in similar terrain. No shooting cracks or collapses. Otherwise, any slab displacement downhill in these areas may often be held up in the compression of the slopes, given how thick the slab has become.

Got some ok views of the Dyke, steep stuff below Floresta, Axtel 1/2 bowl and 1st bowl, and the track of 2nd bowl. Of course the Kebler corridor too. Noting stood out through the little windows that presented.

Route Description: Gothic Townsite

Weather: Cloudy with light snow much of Sunday but very dense, then light snow into the night with wind at times and some snow movement. The 24 hour snow total was just 4″ with again a very dense water content of 0.45″. The snowpack is at winters deepest of 47″. Currently a little bit of clearing with a light SW wind with the temperature at the 24 hour low of 21F after a high of 29F. December was 2% above average in snowfall and 33% above in water from snow. billy

Avalanches: Widespread Touchy Storm Slabs yesterday 12/31. There was a notable natural avalanche cycle on the Upper Upper West Wall that produced 3-5 large avalanches. This terrain has not been mitigated or skied this season and was predominantly scoured down to rock prior to 12/28. Lingering Storm Slabs were more resistant to explosive and skier testing in our core westerly terrain today. However, easterly start zones that were previously Unreactive reached a tipping point: a single hand charge cleared out almost all of Candies and Sonic to the ground (SS-AE-R2-D2-G FC (100cm x 75m x 150m)). This is southeasterly terrain from about 12k. We also had a small but impressive natural event today on The Crotch apron in a recently wind loaded pocket (HS-N-R2/D1.5-O/G 50-100 cm x 10m x 40m). This is SSW terrain at 11.8k and ran O/G with a crown of 1m at its apex.
Snowpack: We received 45″ of snow with 3.5 inches of water over two storm cycles since 12/28. The second cycle was notable for very warm temps, multiple riming events that laid down thin friable crusts at lower elevations, and several hardness inversions in the new snow.
