Mount Emmons

CB Avalanche Center 2014-15 Observations

LOCATION: Crested Butte Area
NAME: than
SUBJECT: Shredwell
ASPECT: North, North East


AVALANCHES: plenty of wet slide activity that looked to be two days old on s/sw faces in lower part of red well

WEATHER: sunny, warm, light winds up high 10mph range

SNOWPACK: Boot top goodness north face above treeline, boot top with crust underneath in wrong.


Friends Hut Area, Brush Creek

CB Avalanche Center 2014-15 Observations

LOCATION: Brush Creek Area
NAME: Zach Guy
SUBJECT: Friends Hut Area, Brush Creek




SNOWPACK: No signs of instability today except a few rollerballs on steep southerly aspects ATL. Windslabs trending toward unreactive…kicked around on a few pockets and couldn’t get any to budge. On north aspects above treeline, the recent snow (~6″) landed on 1mm near surface facets; that seems were you could trigger a windslab if you found one, but most of these slopes were scoured back by NW to N winds in the past 2 days. Surfaces became wet to moist on SE to S to SW aspects near/above treeline today, with moisture down to the old 3/24 crust interface.
Several profiles on the north face of Crystal Peak (ATL) in areas that didn’t avalanche during early March cycle still showing persistent slab structure, with 60-90 cm of 1F slab over Feb facet layer, ranging from 1.5mm to 3mm in size, generally 4F to F hard. Mixed results from ECTX to ECTP, seemed most concerning in areas with shallower snow depth.


Star Pass, Brush Creek

CBAC 2014-15 Observations

NAME: Zach Guy

DATE: 3/25/15


Around 6″ of new snow since Monday night, drifted areas holding a foot or more in places over frozen crusts.Strong winds from the W yesterday shifted to NW today.  Noted a few small natural windslabs, (D1) on E aspects yesterday above treeline, and skier triggered a few small windslabs today on E to S aspects above treeline.  All D1, 4-10″ thick, failing on the storm interface (crust) or in mid-storm layers, near Star Pass.Still seeing some unsupportive crusts below treeline that haven’t gotten a much refreeze insulated by the fresh snow (4-12″ refreeze). Small rollerballs today on low elevation sunny slopes.  Above treeline feels rock solid below the new snow on sun exposed aspects.

Irwin and Ruby Range

CB Avalanche Center 2014-15 Observations

LOCATION: Kebler Pass Area
NAME: Evan Ross
SUBJECT: Irwin and Ruby Range
ASPECT: East, South, West
ELEVATION: Near and Above treeline


AVALANCHES: Several natural point release avalanches and one soft slab observed in the Ruby Range on south and east aspects above treeline. Didn’t get a good chance to see these avalanches before they where hidden in the shade, but they all appeared to be in the D1 to D1.5 range.

WEATHER: Heavy snowfall and near whiteout conditions Wednesday morning with about 4″ of new snow in an hour or two. Sky became partly cloudy by 1pm with strong solar at times.

SNOWPACK: Irwin storm totals where about 14” on the storm board Wednesday morning, from Monday nights to Wednesday mornings snowfall. Wind patterns where poor for creating windslabs in the area and otherwise the new snow was holding up well on the old snow interface. Snow surfaces became moist on east, south and west when the sun came out mid day.


Ruby Range

CB Avalanche Center 2014-15 Observations

LOCATION: Kebler Pass Area
NAME: Evan Ross
SUBJECT: Ruby Range
ELEVATION: ATL 12,800-11,000


AVALANCHES: One natural soft slab running on the east face of Mt. Owen. SS-N-R1-D1.5-U

WEATHER: Clear through the first half of the day and becoming mostly cloudy by 2pm. Westerly winds where gusting during the first part of the day with some blowing snow, before becoming more sustained at Moderate speeds with more continued drifting.

SNOWPACK: New snow was relatively dense above treeline with drifts up to 25cm deep. We found thin wind slabs 2-4″ thick on many slope and one 6″ thick slab on an isolated pocket. These slabs would pop in hand shears within the new snow, but we didn’t observe any cracking or other signs to instability while skiing slopes over 40 degrees. Small sloughs running within the new snow were the only concern.

Snow surfaces stayed dry today at these elevations and on all aspects toured. Also, there was a lot of graupel, sometimes buried within the new snow and sometimes on the surface, it was like a giant sandbox on some slopes.

Gothic Update

CBAC 2014-15 Observations

We had 3½” last night before clearing and cooling a bit.  Snow has been down to 35″ deep, then up to 37½” and now 37″.  Clouds are starting to move back in and it is cooler with the high so far just 37ºF (average high last week 51ºF with 5 record highs).

During the heat a few days back there was a good bit of wet loose activity including one that triggered a small 2 foot fracture that ran to ground.  billy

Gothic area obs

CB Avalanche Center 2014-15 Observations

LOCATION: Brush Creek Area
NAME: Zach Guy
SUBJECT: Gothic area obs
ELEVATION: 10,000- 12,000


AVALANCHES: More evidence of the recent wet cycle around the Gothic/Copper Creek area. Wet loose and wet slabs, mostly off of E and SE aspects near and below treeline., D1 to D2 in size. Also a few D1 wet loose off of north aspects below treeline in steep rocky areas and D1.5 wet slides off of west aspects near treeline. Surprisingly, we noticed 2 natural D2 wet slabs on northwest aspects above treeline, with starting zones at 12,500 feet. Unknown failure dates on all of this activity, but likely last Tuesday or Wednesday.

WEATHER: Clear skies, warm temps, light winds.

SNOWPACK: Obs from Whiterock area and Snodgrass Area:
Solid refreeze overnight at all elevations (12 inches deep or so) was supportive to boot and skis until 1:00 pm. on SE to SW aspects. After 1:00, started seeing some isolated areas of unsupportive snow below treeline, which likely trended to fully unsupportive but we got off of those slopes. Last night when approaching Gothic, we got a very large collapse on flat terrain after the surface had slightly refrozen.
On north aspects below treeline, the tree shaded slopes held mostly dry snow with a few inches of refrozen wet grains at the surface. More open slopes had wet snow deeper into the snowpack. On northeast aspects below treeline, the snowpack was wet to the ground, mostly supportive on skis but not to boot pen in the afternoon.
