LOCATION: Kebler Pass Area
DATE OF OBSERVATION: 02/17/2015
NAME: Zach Guy

SUBJECT: Kebler Pass Area
ASPECT: South East
ELEVATION: 12,000 ft.

AVALANCHES: Several touchy soft slabs, 4-6″ deep, 15-20 feet wide, running only 20-30 feet, harmless in size, failed above the storm interface. Saw a similar in size natural windslab off of the East shoulder of Mt. Owen. No other signs of instability observed.

WEATHER: Light winds with strong gusts from NW to SW. Periods of moderate snow transport

SNOWPACK: Isolated wind loading just below a leeward, SE facing terrain feature, up to 6″ deep, and some fresh cornice formation up to a foot thick. Otherwise, no wind loading or significant drifting. Could see old snowmobile and ski tracks all nearby bowls.

It’s going to feel like real winter outside. A jet streak will nose over Colorado today, bringing strong winds out of the northwest, with alpine wind chills dipping into negative digits. The notorious high pressure ridge begins to rebuild and then flattens over the west coast, shifting the storm track east again, and bringing warmer weather and clearing skies through Wednesday and Thursday. The chance for more snowfall returns by this weekend as another storm tracks over the state from the Northwest.

Crested Butte Area

CBAC February 17, 20152014-15 Observations

Guide- Jake
Location- Axtell glades
L- 9400-10800
Aspect- NNW

Wx- intermittent snow flurries and upslope wind. Cold, guessing in the 20s (can’t believe that counts as cold these days).

Spx/Avalanche obs- no recent activity noticed by this cowpoke. Anything open with enough of an angle to hit sun was a crustwich on top of facets. A quickie on a NNW open slope at 25 degrees yielded a couple of CTM results under the highest crust, a stout MFC 15 cms thick. Treed and shaded stayed soft.

Paradise Divide Area

CBAC February 17, 20152014-15 Observations

NAME: Evan
DATE: 15-02-16
LOCATION:Paradise Divide Area
ELEVATION: 9000-11000
ASPECT: NE

WEATHER: Pulses of snowfall only added up to a light dusting. Down valley winds were easily blowing this snow around but it all seemed insignificant in the big picture.

SNOWPACK/AVALANCHE OBS: Didn’t make it to ridgeline, so traveled on open slopes below treeline. SH was down 20-30cm and popped some nice clean hand shares. The slab above has lost a lot of cohesion in the last weeks and didn’t seem concerning in our area. Crusty snow surfaces on slopes less then 25 degrees and previous wind affected surfaces on sub-ridges that jutted out from the terrain. No signs to instability.

Snodgrass

CBAC February 17, 20152014-15 Observations

GUIDE(S): Donny
DATE: 15-02-16
ACTIVITY: BC Skiing

LOCATION: Snodgrass
ELEVATION: 9400’ to 11,1140′
ASPECT: N – NE

WEATHER: Waves of convective activity throughout the day, periods of S2, less than 3cm of HST. Temps in mid to low 20s all day. Moderate winds above 10,000’, normal, strong down valley wind near parking lot, evidence of active cross-loading on NE – E features.

SNOWPACK/AVALANCHE OBS: HS 80cm to 100cm. Facets on facets, with some facets in the middle. Found a 10cm-thick layer of slightly more cohesive facets about 10 to 20 cm down from surface. Moderate hand sheers resulted in broken blocks. Surface sloughing on slopes over 45º, but they didn’t entrain much more. No signs of instabilities. Or more accurately, no sign of strong snow.

Cement Creek Area

Mountain Weather February 16, 2015

CB Avalanche Center February 16, 2015Weather

Date: 02/16/2015

Yesterdays forecasts where for the storm track to pass by to our east. Weather discussions this morning are hinting at that storm track moving slightly more west which will help us see some snow today. Accumulations will still be light as most moisture is east of our mountains. We may see some additional orographic snow on the western and northern boundaries of our forecast area, but that may be wishful thinking. The blocking ridge responsibly for the dry weather we’ve seen in January and February begins rebuilding on Tuesday. Leading us into a warming and drying trend through the week. Longer range, it looks like we’ll see another chance for snow next weekend but we’ll have to wait for more details on that.

Today

High Temperature: 20
Wind Speed: 5-15
Wind Direction: NW
Sky Cover: Overcast
Snow: 1-4″

Tonight

Low Temperature: 5
Wind Speed: 10-20
Wind Direction: NW
Sky Cover: Mostly Cloudy
Snow: 0-2

Tomorrow

High Temperature: 20
Wind Speed: 15-25

Coney’s

CBAC February 16, 20152014-15 Observations

NAME: Dave
DATE: 15-02-15
LOCATION: Coney’s

ELEVATION: 9,300′ to 10,903′
ASPECT: N-NE

WEATHER: Sunny, partly cloudy and short period of significant S3 snowfall.

SNOWPACK/AVALANCHE OBS: Dug pit on the northern ridge near 2nd bowl, mostly all faceted snowpack. Saw surface hoar layer 28cm down, was non reactive on a CT test. Snowpack was 27cm of F over 30cm of 4F with the rest of the lower snowpack being F facets.

Snodgrass

CBAC February 16, 20152014-15 Observations

NAME: JSJ
DATE: 15-02-15
LOCATION: Snodgrass

ELEVATION: 9,300′ to 10,600′
ASPECT: SW / W / N / NE

WEATHER: similar to what Donny wrote in his ob, but there was a short period of significant S3 snowfall that accumulated enough to cover the old snow surface.

SNOWPACK/AVALANCHE OBS: Solid MF crust found on westerly aspects. Mostly all faceted snowpack found on northerly aspects with no slab evident, and on terrain steeper then 35*, facet sluffing to the ground was evident but slow, and not far running.

Snodgrass

CBAC February 16, 20152014-15 Observations

NAME: Donny
DATE: 15-02-15
LOCATION: Snodgrass

ELEVATION: 9,400’ to 11,140′
ASPECT SE – E

WEATHER: 1000: 36ºF, calm to light wind from north, visibly stronger winds aloft, partly cloudy. PM: Snow flurries, short periods of S1, no accumulation, graupel mixed in, cloud band must have been low-elevation because sun could still be felt; moderate wind from the north, no temp recorded, but clearly it cooled somewhat.

SNOWPACK/AVALANCHE OBS: Dug a pit at 10,250’ on a 37º east aspect. HS 90cm. No buried SH found. 2mm DH found at base. Most remarkably the old 12/13 interface had the largest facets – some DH evident. Had repeatable CTH22 (SC) on this interface. Top 10cm going through diurnal faceting. Two, old crowns (D2-R1) still present in “Rental Shop” along with a loose snow slide from the top. This is not relevant to today’s conditions, but it was a great teaching tool.
