Peeler Basin and Oh-Be-Joyful Basin

CB Avalanche Center2014-15 Observations

Name: Zach Guy
Title: Peeler Basin and Oh-Be-Joyful Basin
Location: Kebler Pass Area
Date of Observation: 12/13/2014
Aspect: North, North East, South
Elevation: 9,700′ to 12,200′

Avalanches: Shallow facet sluffing on anything northerly facing. Nothing impressive, except for the one guy in our group who crashed in front of his sluff and got pummeled.

Weather: Clear skies all morning. Clouds began developing around 2 p.m. Warm temps, moderate SW winds. No precip.

Snowpack: More of the same. South aspects near treeline had wet grains (facets and meltforms) to the ground, HS around 30-40cm. North and northeast facing slopes above treeline held a continuous layer of ~3″ of near surface facets (fist hardness), sitting over a variable distribution of old, stiff snow or weak, unsupportive snow. Descending in elevation, the snowpack transitioned to mostly all facets and unsupportive on skis. See video

Crested Butte Area

CBAC2014-15 Observations

Name: Level 1 Avalanche Class
Date of Observation: 12/13/2014
Aspect: North East, East, Southwest
Elevation: BTL

Weather: Few clouds midday becoming overcast in the afternoon. Calm winds and warm temps. Gusty winds and and S-1 grapple started around sunset.

Snowpack: We were hunting slabs in the area and the slabs where all faceted out. One group did find a 4f-1f midpack on an isolated wind roll. Otherwise on NE/E aspects the HS was about 40cm on average and all facets. In the bottom 2/3 of the snowpack the 1-4mm facets have gained some strength and are 4f- in hardness. SW aspects consisted of a thick crust over F hard facets. On all aspects toured SH was living large unless it was on steep enough southern aspects to be melted by the sun.

Crested Butte Area

Name: TNA
Title: confectionery
Date of Observation: 12/13/2014
Aspect: North, North East
Elevation: BTL

Avalanches: None seen

Weather: Warm, sunny, no wind

Snowpack: Skied 800 vertical feet of factus awesomnus in 2.5 bowl Snodgrass. You ain’t livin’ until you’re skiing facets. Although, about midway down there was some sort of 4 inch thick supportable layer out in the open shots about four inches down in the pack. Windboard?

Saturday 12/13 Weather

CB Avalanche CenterWeather

Date: 12/13/2014

As of 6am, the much anticipated cold front is racing across the Utah desert. This north-south oriented cold front will break the 20-day long drought and bring significant snowfall to the Elk Mountains. Look for the storm to begin warm and wet, and steadily cool off throughout the weekend. South winds average 25-30 mph this morning with stronger speeds above treeline, then wind will decrease this afternoon after the cold front passage around 3pm. Tonight will be the heaviest shot of snow as the winds aloft veer from southwest to westerly, funneling moisture into the Crested Butte area. Sunday we will see continued snow, with forecast models still hinting at total storm accumulations in the 8-14″ range by Monday morning.

Mt. Owen

CB Avalanche Center2014-15 Observations

Name: Zach Guy
Title: Mt. Owen
Location: Kebler Pass Area
Date of Observation: 12/12/2014
Aspect: North, North East, East
Elevation: 11,000 – 13,000 ft

Snowpack: For ATL slopes over a week out since last snow, the snow surface is remarkably unscathed by wind. The Dec 1 snowfall has metamorphosed to rippled near surface facets (~3″ thick), over older, stiff windboard. Isolated gulley features have a thin windcrust over the NSF. Breakable MF crust as the aspect changes to ESE. No signs of instability on slopes up to 45 degrees, except for shallow facet sluffing, enough to require heads-up sluff management. Can’t recall the last time I saw such a widespread PWL so well preserved on the surface at all elevation bands here in CB.

Mount Emmons 12.11.14

CBAC2014-15 Observations

Name: Irwin Guides (CBMG)
Location: Red Lady Glades
Elevation: 9200-1200
Aspect: SW
Weather: Sunny blue bird, no wind or precip

Snowpack/Avalanche Obs: Snow at lower elevations is a mixed bag of melt freeze sun crust and powdery snow ranging in depth from 10-20cm. One collapse was observed at 12000 at the goal posts. No instabilities seen. The glades have a sun crust on W and south facing slopes that moistened throughout the day. Shaded areas have powdery snow. Variable depth of snow averaging at about 30cm at mid to upper elevations. Surface hoar in shaded areas. Thin pack towards the bottom.

Schuylkill Ridge 12-11-14

CB Avalanche Center2014-15 Observations

Name: Dustin Eldridge
Title: Schuylkill Ridge 12-11-14
Location: Paradise Divide Area
Date of Observation: 12/11/2014
Aspect: North, North East, East
Elevation: 9000-11300

Avalanches: None observed.

Weather: Warm and calm. Light high elevation clouds. Snow surface was moistened on southerly aspects.

Snowpack: Low elevations held almost entirely faceted snow on shaded slopes with slightly more consolidated pack on NE faces. Crust softened by the midday sun was evident on S-facing slopes up high. Facets abounded under the crust, snow height around 40-50 cm. Pit dug on N-aspect , 37 degrees, 11,300 ft, showed 75 cm of snow with Fist-hardness (2-3 mm faceted crystals) down to 50-60 cm. From there the pack was slightly stiffer (4f, 1mm wind compacted)) down to about 5 cm (2-3 mm facets) where a depth hoar layer was evident. Extended column test showed ECTP 18, Q2.5 on the ground.

Weather Forecast for Friday, December 12th

CB Avalanche CenterWeather

Date: 12/12/2014

One more day of dry weather until the strong Pacific storm battering California ejects eastward and brings all this mild, balmy weather to an end. Expect to see high clouds increase today and tomorrow ahead of this storm, and relish those mild temperatures until a cool, moist, fast moving system takes hold of our area mountains Saturday night into Sunday. We should be looking at 5-10 inches of snow, with potential for a bit more by Monday morning.

Weather December 11, 2014

Date: 12/11/2014

Don’t be bummed by the near-zero temperatures in town this morning. Our mountain stations are downright balmy with temps hovering near freezing and forecasted to rise into the 40’s. Inverted temps with mild mountain weather will continue through Friday. This morning, a strong Pacific trough is landing on the West Coast. As it moves inland, it will split and weaken, with a closed low tracking to our south and bringing snowfall to the Elk Mountains on Saturday evening into Sunday. Its not the most favorable pattern for this area, but we’ll take what we can get, somewhere in the ballpark of 4 to 7″.
