Gothic 7am weather report

CBACCBAC Observations

Date of Observation: 12/24/2021
Name: Billy Barr

Zone: Southeast Mountains
Route Description: Gothic townsite

Observed avalanche activity: No
Weather: Thursday had light snowfall but very dense in the morning, picking up in the afternoon with 5″ new snow and 0.64″ water by sunset. After dark it became heavy and stayed that way overnight with thankfully only minimal wind with an additional 17½” of snow and 1.60″ of water. This gave a 24 hour total of 22½” and a whopping 2.24″ of water- this time period was 10% water content, remembering that long term December average is 6.35%. The high-temperature yesterday was 33ºF and that came towards midnight. The overnight low was 29F and that is the current with no wind at this time and moderate snowfall. The snowpack sits at winter’s deepest of 38″.

No visibility but i could hear some slides running while i was out, though off the face of Gothic this is common. –I shall enjoy the morning cup of tea and an orange. billy

Cement creek

CB Avalanche CenterCBAC Observations

Date of Observation: 12/23/2021
Name: D K

Zone: Southeast Mountains
Route Description: Cement winter TH up Warm Springs and down Walrod

Observed avalanche activity: No
Avalanches: None
Weather: Steady snowfall at 1″ per hour. 3″ of accumulation at 430pm on 12/23. Currently 12″+ in CBS at 7am on 12/24.
Snowpack: Mostly poked at E facing slopes around 9200. Found a mix of discontinuous crusts up to 1cm thick over facets and new snowfall resting directly on facets depending on tree coverage. The Walrod slide path start zone was briefly in view and any anchoring vegetation was covered.

Weak snow, waiting for a slab near town

CB Avalanche CenterCBAC Observations

Date of Observation: 12/23/2021
Name: Zach Guy and Zach Kinler

Zone: Southeast Mountains
Route Description: Red Lady Ave and Elk Ave avalanche terrain features near downtown Crested Butte

Observed avalanche activity: No
Snowpack: The snowpack is shallow, weak, and entirely faceted, with a couple of surface hoar layers. The amount of snowfall over the next week will directly influence slab size on these slopes. See profiles.

Southerly terrain observtions up high and down low

CBACCBAC Observations

Date of Observation: 12/22/2021
Name: Eric Murrow

Zone: Northwest Mountains
Route Description: Snowmo to Poverty Gulch and skin up southernly terrain of Mineral Point/Augusta.

Observed avalanche activity: No
Avalanches: nothing new observed
Weather: Clear skies in the morning gave way to thin, high clouds in the afternoon. Temperatures and radiation were just strong enough to moisten surfaces on southerly aspects. Winds were generally light with a few periods with moderate gusts from the southwest.
Snowpack: I traveled on southerly facing terrain from 9600 to 12500 feet. I commonly found dry, faceted snow surfaces on slopes less than 20 degrees and thin (.5-2cm) melt/freeze crusts on steep southerlies near and above treeline. As you moved towards southeast and southwest aspects crusts became wafer-thin, or non-existent at the surface. Small facets (generally .5mm, but up to 1mm) were present below the surface crusts and occasionally above the crust (radiation recrystallization). Additionally, there is a layer of facets roughly 1 foot below the surface on southerly slopes (see profile). Below treeline crusts on steep slopes facing due south increased to around 4cm thick, but not fully supportive to skis (ugly breaker crust skiing).

Inviting Instability

CB Avalanche CenterCBAC Observations

Date of Observation: 12/21/2021
Name: Cam Smith

Zone: Northwest Mountains
Route Description: The southeasternmost NW mountains

Observed avalanche activity: No
Avalanches:
Weather:
Snowpack: S, SW, and W slopes BTL and NTL near Splains Gulch- open areas and sparsely treed areas had sun crusts rang from Ibuprofren crust to CBD crust on the “Than Acuff knee pain scale”
Densely treed areas have held up nicely on the surface from last weeks wind and this weeks sun

N slope BTL near Ohio Pass- in open areas there was surface hoar so big and tall that every step of skinning through it sounded like shattering glass

Facets on southerly facing aspects

CBACCBAC Observations

Date of Observation: 12/21/2021
Name: Evan Ross

Zone: Northwest Mountains
Route Description: Washington Gulch 9,500ft to 11,500

Weather: Mostly cloudy sky in the morning, became clear for the rest of the day.

Snowpack: Stopped at 3 different spots to take a look at snow surfaces on southerly-facing slopes. The primary layer of concern in all three locations was facets on top of the crusts.

SW, 10,500ft, 33 degree slope. Dry, lightly faceted < .5mm grains above a 1cm crust. HS 55.

SE, 11,500ft, 33 degree slope. Dry, well-developed 1mm facets with multiple lines of striation, above a moist 4cm crust. HS 50.

SSE, 11,500ft, 34 degree slope. Dry, well-developed 1mm facets with multiple lines of striation, above a 3cm crust. HS 50.

Facets abound on Schuylkill Ridge

CB Avalanche CenterCBAC Observations

Date of Observation: 12/21/2021
Name: Travis Colbert

Zone: Northwest Mountains
Route Description: Up the standard (but currently a bit wonky) skintrack. Skied a few runs and did not encounter a single slab (except for obvious pillows of wind compacted snow just of the ridge). Weak, faceted snow to the ground. Fun for now, but about to get really interesting if it snows as much as forecasted.

Observed avalanche activity: No
Weather: No wind. Sunny skies. Cold in the shade.

Red Lady Glades trespassing PSA

CBACAnnouncements, Backcountry Notes, News

Dear Community,

In an effort to preserve everyone’s access to Red Lady, we are asking backcountry travelers to respect the restricted access boundaries around the Mt. Emmons Wastewater Treatment Plant Site. This is the working area to your left as you are climbing the Red Lady skin track. The Site Supervisor on Mt. Emmons has encountered an increase in backcountry travelers on their water treatment plant property this year. They have asked us to help spread the word that while the Red Lady skin track is currently open, they may have to enforce a no-trespass policy for the community’s safety and the security of their facilities if it continues. The mine regularly operates heavy equipment and snow removal machinery on their roads and does not want a collision with skiers or riders. Additionally, the area of concern includes the Keystone Snow Course established in 1961 by the NRCS for measuring snow water equivalent in the Upper Gunnison watershed. That snow course and the surrounding area lie on private land. Continued impacts on the area could compromise important data collection vital to our water source. The standard fall line egress from Red Lady Glades does not pass through this private property, the route that veers east towards the bottom does. Please familiarize yourself with this image of the property boundary if you enjoy skiing Red Lady Glades.

Thanks, Crested Butte Avalanche Center
