Irwin Tenure

CB Avalanche Center2014-15 Observations

LOCATION: Kebler Pass Area
DATE OF OBSERVATION: 01/15/2015
NAME: Irwin Guides (CBMG)
TITLE: Irwin Tenure
ASPECT: East, South, West
ELEVATION: 10,000-12,000

SNOWPACK: 10” Sunday-Tues…ended Jan dry spell. Storm snow 10-20 cm, evenly distributed across terrain. Minor wind affect up high. Fell on mostly crusts and some “baked SH”. No signs of instability other than sluffs in past few days. Last two days of sun and warmup left breaker crusts on everything except west and low angle.

Kebler Pass Pocket

CB Avalanche Center2014-15 Observations

Location: Kebler Pass Area
Date of Observation: 01/14/2015
Title: Pocket
Aspect: East
Elevation: 12000

Avalanches: Small pocket released on steep, East cliffy terrain above treeline. Looked like new storm snow that had been recently loaded.

Weather: sunny, strong winds at ridgelines

Snowpack: 4-7 inches of new low density snow that fell over weak facets/windboard in the shade and melt freeze-crust or solar aspects

Date: 01/15/2015

Another beautiful day is in store, with mild mountain temperatures, light winds, and plenty of sunshine the product of strengthening high pressure. Grab your powder tool of choice and climb above the inversions. We’re sitting at -12F in town this morning, but mountain temps should reach the 30’s today. High clouds will start to move in tomorrow ahead of a weak shortwave dropping in from the Northwest, which shows up Friday night into Saturday. Snow accumulations look to be a few inches at best.

Paradise Divide

CB Avalanche Center2014-15 Observations

LOCATION: Paradise Divide Area
DATE OF OBSERVATION: 01/14/2015
NAME: James Tonozzi
TITLE: edge of paradise must be heaven
ASPECT: North
ELEVATION: 11,000 to 8,500

AVALANCHES: R-2 D1 sliffing in new snow. no persistent slab activity in well protected true north. NEXT to a tree line but in the open on 1500 vert foot face.
observed some huge hang fire not in my drainage but ready to go. Thankfull to be in the North Paradise Zone with a little more depth and consistency in the pack. Not much wind in the last 5 days and in yesterdays snowfall.

WEATHER: Sunny and warm

SNOWPACK: Solid pack, recent 12-16 staying reasonably well behaved. True North aspect. some minor sluffing in the new snow . Skied on completely shaded north face on pitches up to 45 degrees. Saw some R 2 D1 sluffs in a convexity and below rock bands but super solid in my non cross loaded slice. Isolated a column at the top of face 120 CM deep . Had to beat the sheet out of it to get it to move.

Mt. Emmons

CBAC2014-15 Observations

GUIDE(S): JSJ
DATE: 1/14/15
ACTIVITY: BC Ski
LOCATION: Red Lady Bowl
ELEVATION: 9000′ – 12,400′
ASPECT: SSE

WEATHER: Clear. cold at TH in am (5F), warm in sun. No wind until about 1030 am. Light but steady and cold out of North.

SNOWPACK/AVALANCHE OBS: About 10-15cm new snow from yesterday. very light and low density and no wind transport was obvious. resting on stout crusts on southerly slopes 30* or steeper, but bonding seems to be good. Surface storm snow thickening and heating up on steep south slopes by mid-day. 2 small but noticeable collapses felt while traveling on a shallow snowpack zone on ridgecrest near treeline. No other instabilities seen while traveling on slopes >35*.

Jan 14 Coney’s Ridge

CB Avalanche Center2014-15 Observations

Location: Crested Butte Area
Date of Observation: 01/14/2015
Name: Billy Rankin
Title: Jan 14 Coney’s Ridge
Aspect: East
Elevation: 11,000′

Avalanches: Old Avalanche way left in Bowl in classic convexity. A couple very small slides observed off West face Gothic just below ridgetop, A couple small shallow windslabs far end of Schuykil Ridge. Also small insignificant D1 or smaller.

Weather: Clear, high temps felt in the 20’s, strong solar radiation, light wind. Winds up high blowing plumes off Gothic peak and Baldy looked North, maybe North East.

Snowpack: Skied far left side of bowl, avoiding steeper convex roll. First turn of the ridge skis punched through a lot of the snowpack. On tenth turn my partner felt a small collapse right below the ridge that produced a 15′ wide crack. Skiing was feeling trap door ish with very weak mid pack. Windloading patterns on Gothic and Schuykil Ridge looked from winds out of the NNW.

The closed low that brought unsettled weather earlier this week is shifting south and east through Arizona and New Mexico today. Clouds have already cleared out as high pressure and dry northwest flow return to our region. The rest of the work week will bring sunny skies and a gradual warming trend in the mountains, while inversions set up in the valleys. A chance for snow returns this weekend.

Taylor Peak

CB Avalanche Center2014-15 Observations

Location: Brush Creek Area
Date of Observation: 01/10/2015
Title: Taylor Peak
Aspect: South East, South
Elevation: ~11,500

Avalanches: This hard slab avalanche appears to have stepped down around the cliff band. Observed 10th of January but expected failure occurring post late December cycle.

Weather: Sunny, 29 degrees F.

Anthracite Mesa

CBAC2014-15 Observations

GUIDE(S): JSJ
DATE: 1/13/15
ACTIVITY: BC Ski
LOCATION: Coney’s
ELEVATION: 9000′ – 10,800′
ASPECT: N-E-SE

WEATHER: Overcast through most of day. Snowing S1 with periods of S3. Calm winds.

SNOWPACK/AVALANCHE OBS: 20cm storm snow with no wind. Preserved surface hoar layer found below the new snow but finding it non-reactive to quick informal stability tests. An instability was found in the top 5-10cm of the snowpack at what was seeming to be a slight density change in the recent storm snow, as it got heavier with rising daytime temps during the storm today. Minimal problem now…worth re-visiting at it gets buried deeper. Triggered 2 small (D1) loose snow slides on steep low elevation terrain features with convex rollovers, as expected. No other instabilities seen.

Gothic

CBAC2014-15 Observations

No snow yesterday despite clouds but then starting after dark.  Light but steady all night with 5½” new and water a light 0.28″.  No wind.  Snowpack at 35½”, below average but deepest so far this winter.  Snow surface was hard and crusty in most locations and this light density snow will probably not effect it too much for now.

Cloudy and calm but no snow currently.  Overnight temp. range just 19 to 21ºF.
