Avalanches:
Weather: Light Thursday snow with 4″ sunrise to sunset (0.28″ water), the light overnight snow with 5″ new so far and snowing lightly. Wind is calm and snowpack up to a new high of 91″ deep. No visibility and there has been none for days- it is like living with s bag over my head. A white one. I will give 24 hour totals after 7.

5 ft + on Emmons

CB Avalanche Center2016-17 Observations

Location: Crested Butte Area
Date of Observation: 01/12/2017
Name: Zach Guy
Subject: 5 ft + on Emmons
Aspect: South
Elevation: 11,100 ft

Avalanches: Had views of the lower runout of Coon Bowl and the starting zones of a couple Climax Chutes and saw no signs of recent activity.
Weather: Obscured skies, S-1 to S1. Light winds with light transport at NTL location.
Snowpack: HS on a flat, windsheltered slope NTL was 280cm. Snowpack is settling quickly, ski pen was about 20 cm and boot pen was about 60 cm. Low angle is skiing nice now.
Dug one pit on a windward, S aspect NTL. The January 1 crust was 85 cm above the ground and buried by a 155 cm, right-side-up slab from F down to P-. ECT produced several non-propagating fractures in mid-storm layers. A deep tap ECT crossed the column on 3rd hit, sudden planar, on the January 1 crust. The weak layer was 0.5 to 0.7 mm rounding facets. No signs of instability breaking trail along a low angle, gladed ridgeline.

S aspect NTL. 5 foot slab over facet/crust layer.

HS in windsheltered area NTL. ~280 cm

Kebler Road/ Irwin Obs

Subject: Kebler Road/ Irwin Obs
Aspect:
Elevation:

Avalanches: Havlick and Ruby Mining District resident both heard a very large Avalanche off Ruby at 0835. Saw one large crown above Elk Basin.
Weather: Continues to snow S1-2.
Snowpack: Snow: 18″ 1.8″ SWE since 1/10 at 1600 (40hrs). Storm stake was completely buried, dug it out, 41″ with storm water 6.6″ since Jan 8th. Total snow since 1/1 is 98″ with 11.3″ water.
Kebler has 2-3′ on the road, more in classic wind loaded areas. The road is starting to merge with the surrounding terrain. One single track had run the gauntlet early this AM. We only saw evidence of 2 of the 7 Sisters have avalanched. We called off operations upon Snow Safety Team arriving to the trailhead this AM. We need a day to muck out, let alone high avalanche danger. Over 100″ since Jan 1 and the roads are extremely soft and the slopes are the most loaded I’ve in my 20 years.

Gothic 7 a.m. update

Subject: Gothic 7 a.m. update
Aspect:
Elevation:

Avalanches: No idea of slide activity- cannot see a thing.
Weather: Light snow during the day Wed. with 5″ new, then strong wind late day and only light snow before wind lets up and snow increases some, dying down around 3 a.m. or so. The 24 hour totals are 12 1/2″ new snow and 0.86″ of water as the snowpack is at years deepest of 88″. Currently light SW wind and a very light snow and of course obscured clouds, which is all we have had for the past week or century (I get confused anymore). I hear it may clear by June though.

Subject: Storm Continues, Big Avalanches
Aspect: East, South East, South
Elevation: NTL

Avalanches: Big slide in E-SE-S facing terrain Near treeline (Land of Lost) from big airblast in PM, obvious windloaded terrain. Failed 3-5ft deep, on NYE crust, and stepping down to ground in places on 2-3mm facets. HS-AE-R3-D2.5-O
Weather: Showery throughout day, period of heavier snow after lunch, then another lull at 1545. SW-W winds steady 30mph gusting 50-60mph range throughout day at ridgetop. Temps in teens and low 20s.
Snowpack: Snow was showery, 3″ accumulation throughout day, bringing storm water totals 4.8″ water since 1/8 and 7.5″ since 1/1/2017.

Roadside avalanche obs

Location: Crested Butte Area, Cement Creek Area
Date of Observation: 01/10/2017
Name: Zach Guy
Subject: Roadside avalanche obs
Aspect:
Elevation: BTL

Avalanches: Lots of natural soft slab avalanches below treeline, mostly D1.5 to D2 in size, various aspects. Limited vis of higher elevations. Observed one large powder cloud come off of NW aspect NTL of Whetstone, but couldn’t make out the crown. One debris pile off of Whetstone looked about D3, came down from alpine.

Naturals above East River

CB Avalanche Center2016-17 Observations

Location: Crested Butte Area
Date of Observation: 01/09/2017
Name: Zach Guy
Subject: Naturals above East River
Aspect: North East, East, South East, South West
Elevation: 9,600 to 9,300 ft

Avalanches: See photos. Drove by Peanut Lake Road around 2 pm and none of that had run. Traversed across East River paths and there were only a few crowns. Largest slide I saw was SS-N-R3-D2.5-O/G on a SW aspect NTL.
Weather: PM tour. S5 dendrites transitioned to S1 graupel to freezing rain. Overcast and warm temps. Moderate winds, strong gusts below treeline. Snow is so dense at this elevation that there wasn’t much transport.
Snowpack: About 20″ of top-heavy new snow. Spooky few signs of instability (no cracking or collapsing, with a few kicks and jumps above steep rollovers), but the big red flag today was the massive amount of heavy new snow. Trail breaking on skis was knee to thigh deep. Some moist/wet rollerballs on steep terrain. Didn’t go onto anything steep.

SE aspect BTL near East River. VIewed from a distance, but maybe a 3-5 ft crown?
