Paradise Divide Snow Ob

CB Avalanche Center2015-16 Observations

Location: Paradise Divide Area
Date of Observation: 11/17/2015
Name: MR
Subject: Paradise Divide Snow Ob
Aspect: North East, East, South East
Elevation: 9,500-11,200



Weather: strong gusting winds out of the northwest. Intermittent spitting snow. Mid 20’s temp?
Snowpack: dense slab of new snow, some wind stiffened, on skin track on east to northeast aspects, some collapsing and whomphing. Hasty pit showed 8-10 inches of dense snow popping cleanly on the interface. Surprised to not see any avalanche activity in the zone, or get any reaction skiing though we mostly avoided 30+ degree slopes.

Rustler’s Gulch snowpack

CB Avalanche Center2015-16 Observations

Location: Paradise Divide Area
Date of Observation: 11/19/2015
Name: Zach Guy and Evan Ross
Subject: Rustler’s Gulch snowpack
Aspect: West, North West
Elevation: 10,000 – 11,400 ft.

 

Avalanches: Good views of Gothic, Baldy, and Belleview. Looks like one recent crown on a NE aspect above treeline on Gothic, failing near the ground a foot or two deep. SS-N-R2-D1.5-O/G. Otherwise, no recent activity.
Weather: Broken to scattered cloud cover. Light winds at our elevation but plumes from NW winds off of 12k ft peaks. No precip.
Snowpack: HS averaged 40 cm below treeline. The bottom 5-10 cm is 1.5mm moist facets (F+), and above that is settled snow from recent storms (4F to F, rounds or DF’s). No signs of instability. As we approached near treeline elevations, snowdepth and structure became much more variable due to wind effects. Basal facets were dry, and in some places capped by low density recent snow or in others capped by dense wind drifted slabs up to 2 feet thick. These slabby areas were small and isolated in distribution. We observed some small collapses and cracks when crossing these windloaded pockets.

Anthracite

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.

Ruby Range

CB Avalanche Center2015-16 Observations

Location: Kebler Pass Area
Date of Observation: 11/15/2015
Name: Tyler Lee
Subject: Ruby Range
Aspect: North East, East, South East
Elevation: 10,300-12,500

 

Avalanches: 2 point release slides on N-NE aspects (R1,D1)
Weather: Wind blowing on ridges to the E-NE (cornices forming over E-NE aspects). Bluebird day (snow consistency stayed the same throughout the day).
Snowpack: Pit: fracture on ECT 16 (no shear break-off), 10 cm from the base. New storm layers appear to be consolidating with old storm layers. Sun crust forming on southern aspects.

Elevation: 9,500-11,000

Avalanches: no avalanches observed
Weather: Clear, slight overcast. Calm winds

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).
