CB Avalanche Center2018-19 Observations

Location: Crested Butte Area
Date of Observation: 01/25/2019
Name: Steve Banks

Subject: CB Zone
Aspect: South East
Elevation: 9-11,000

Avalanches:

Small windlslab in Red Lady Bowl fresh on 1/24 night? Evidence of several small dribblers, sluffs and cornice falls in the bowl over the past few days.

Weather: Mostly sunny and felt warm, but cold if not in the sun. Moderate winds in the AM becoming light in the PM. Lots of blowing snow up high. No precip

Snowpack: 4-6″ of new snow from yesterday/last night was becoming moist in the sun. Below was a soft crust from prior sunny days and another just below that. Without digging a pit, the snowpack felt supportive but variable. Ski pen never more than 8″ but ski pole could be pushed over 130cms into the snow in some places, but resisted in others. Lots of snow moving onto NE/E slopes NTL and ATL.

Elevation: 9-12500

Avalanches:

Purple Palace ENE. The Baldy wind slab is south. The wide propagating slab looks a few days old and is out Rustlers Gulch SE. Good view out there and didn’t see any other slabs.

Morning trip up Washington with no signs of instability. Plenty of previous wind transported snow and still transporting this morning.

Natural Avalanches?

Subject: Natural Avalanches?
Aspect: South East, South

Avalanches:

Not sure, if you guys had noticed those already, but went to fly my drone and saw these two north of the Snodgrass/Gothic trailhead – above the stables. Not certain what the name of that mountain is – No Name Mountain? (Forecaster note:  White Mountain)  Anyway, wanted to get close and get a video of it, but it turned out to be way further than I thought and ran out of battery. The two adjacent faces went down. Was there right at sunset…

(Forecaster note:  These avalanches were first observed the morning of 1/23, but we really appreciate the observation and new photo angle of these avalanches!)

Weather: It was nuking (really windy) on those ridges in the morning. I can see those from my balcony, and usually check to see, if it is windy up high.

Elevation: BTL

Avalanches:

None seen

Weather: spotty snow and plenty of wind transporting snow onto the N/NE aspects

Snowpack: Deeper than before, I know because the stick in the picture below used to poke me in the head while skinning, today it poked me in the shoulder.

Mountain Weather for 11,000ft

CB Avalanche CenterWeather

Date: 01/25/2019

Cold, and moist northwest flow continued to produce cold smoke into the evening in favored mountains west of Crested Butte. Cold temperatures and moderate northwesterly winds will drop windchills into the -30ºF range as last night’s weak system slowly departs. We are squeezing any potential moisture out by the skin of our teeth with favorable orographics. A big, dreaded ridge of high pressure sits to our west, and the large scale trough lingers across the eastern half of the nation. Looking ahead, that westerly ridge slides overhead, bringing mostly dry conditions this weekend, with the next potential storm later next week.

Skier Triggered Avalanche Near Miss

CB Avalanche Center2018-19 Observations

Location: Kebler Pass Area
Date of Observation: 01/25/2019
Name: Eleven Cat Ski Guides

Subject: Skier Triggered Avalanche Near Miss
Aspect: South
Elevation: 11,000, NTL

Avalanches:

We had a near miss when a guest, unintentionally, skier triggered an avalanche on a South facing aspect around 14:00. It failed on the 1/15 interface on small grained facets. There had been explosive testing on the slope in the morning with no results. 14th skier pushed right-hand boundary into untracked snow and the slab released when he was mid-slope. He skied out left at the bottom and was unaware of the slope had released above him. See attached pics and profile. PM report has details

Weather: S1/S2 snowfall throughout the day. HST 10″.

Cement/Double Top Slides

CB Avalanche Center2018-19 Observations

Location: Cement Creek Area
Date of Observation: 01/24/2019
Name: Cosmo Langsfeld

Subject: Cement/Double Top Slides
Aspect: North East, West
Elevation: 9400-10600 ft

Avalanches:

Noticed these slides on my way back to the trailhead around 3pm. One small slide on E-NE facing slope on Doubletop. Not sure when this slid. Looked fairly fresh. Also two small slides low on Cement, West aspect,~9500ft. I think these slid sometime between 930am and 3pm on 1/24.

Weather: Snowing and low clouds early in the day. Clearing as the day went on. Wind blowing hard enough to transport snow in the valley bottom in the morning. Wind died down and it was calm by mid-morning. Very cold down low. Pleasant off the valley bottom.

Snowpack: Supportive. No obvious signs of instability on the way out. Dug down on low angled NE facing meadow BTL (~10600′). Snow depth 140cm. Top 30 unconsolidated. 110-95 Fist. Crusts at 95 and 85 cm above ground level with a distinct layer of sugar above the 85cm crust. Between the two crusts, 2 layers 1f-4f with softer snow between those two layers at 90cm above ground level. Below 85cm, snow was 4f to Fist, softening with depth until it turned to sugar somewhere around 35cm above ground level, grain size increasing with depth. Leaving the pit, when I got about 6 feet away, the snowpack settled audibly.
