Anthracite

CB Avalanche Center2015-16 Observations

Location: Kebler Pass Area
Date of Observation: 11/16/2015
Name: EM
Subject: Anthracite
Aspect: North, North East, North West
Elevation: 10,000 – 11,500

 

Avalanches: There were two R1D1 slides on an open NE slope. They appeared to be very shallow, only involving the top few inches.
Weather: Light snow during midday. Winds were generally moderate but with some strong gusting at ridge top. Visibility was limited. Observed wind transporting snow in several locations.
Snowpack: New snow accumulation at 1pm was about 7 inches. Snow surface in open areas was starting to stiffen and crack. Cracking was shallow and only extended a few feet in front of skis. Didn’t experience any collapsing.

Mount Baldy/Schofield

CB Avalanche Center2015-16 Observations

Location: Paradise Divide Area
Date of Observation: 11/15/2015
Name: Ian Havlick
Subject: Mount Baldy/Schofield
Aspect: North, North East, East, South East, South
Elevation: 10,000-12,000

Avalanches: only old avalanches observed. Baldy slide Zach reported, as well as a few other similar slides down to the very earliest, slickest October snow on N-NE facing slopes N/ATL in feeder gullies of Emerald Lake Coulior, and coulior proper, which ran all the way to outlet creek of Emerald lake during last cycle.
Weather: Mostly Clear, variable non-transportable speed breeze at times but generally calm. High clouds rolled in midday, then diminished once out of the field. Fairly strong radiation, but cold in shade.
Snowpack: Mixed surfaces on all aspects and elevations travelled and glassed. In protected and non-disturbed areas (willows, glades, hollows) snowpack carries a slight slab still from our November 4-6th storm (4F-) sandwiched by a 2mm facet layer near the ground (october snow), and ~ 10-15cm of 1mm facets at the surface (November 10th storm). Varying thicknesses of wind crust from 1-10cm of pencil hard snow, with thin skim of near surface facets on top. Average snowpack depth ranged from 40-60cm.

Only surface hoar I observed was in very sheltered (from sun and wind) areas, particularly in drainages and near creeks (as one would expect). Slick wind buff dominated high elevation northerly aspects from our last system’s strong NW winds as it exited.

Southerly aspects BTL were quite moist all the way to the ground, and ATL were crusty (2-4cm thick).

Owen/Ruby

CB Avalanche Center2015-16 Observations

Location: Kebler Pass Area
Date of Observation: 11/15/2015
Name: EK
Subject: Owen/Ruby
Aspect: North East, East, South East
Elevation: 10,300-12,400

Avalanches: Small R1 D1 point release under high point of Saddle on Owen.
Weather: Clear skies, sunny, warm. Winds picking up in the afternoon coming from the NW
Snowpack: NE-E-SE consolidating after most recent storm. Snowpack depth above 11,800′ ft ranged from 80cm-120cm in most areas. There were 3 apparent interfaces, the weakest layer remaining at the base. Rapid loading of E-SE beginning in the afternoon.

Subject Ruby Range Obs
Aspect: North, North East, East, South, South West, West

Avalanches: several D2 avalanches on Axtell, and near the Ruby Dyke, one appearing to be triggered by wildlife.
Weather: Clear, cold morning- then warming with strong radiation and light westerly winds (non transport speeds).
Snowpack: Shallow. 20-50cm average HS with deeper wind drifted areas behind trees and ridges. 3 distinct layers on west facing slope where I dug, October melt-freeze, November 4-6th storm, and our most recent November 11th storm. Q2 shears in CT and ECT tests on melt freeze crust that form on Nov. 6th storm. 1-2mm facets/crust combo.

Skier triggered Avalanche near Splains Gulch

CB Avalanche Center2015-16 Observations, Avi-map 15-16

Location: Kebler Pass Area
Date of Observation: 11/11/2015
Name: Heather Bradford
Subject Skier Triggered Avalanche Near Splains Gulch
Aspect: North
Elevation: 9600′

Avalanches: One skier triggered R1, D1 soft slab Avalanche. Skier caught but not buried. Crown height approximately 35cm. Failed at the interface between basal facets and the snow from last weeks storm cycle. Starting zone angle approximately 37 degrees.
Weather: Overcast. Light snowfall and light wind, no snow transport observed. 3:00pm.
Snowpack: Snowpack is minimal at this elevation, only measured 40-50cm of total snow. Snow from the past storm cycles have come in right side up but it is sitting on top of 1-2cm of basal facets.
