Sensitive soft slabs

CB Avalanche Center 2020-21 Observations

Date of Observation: 04/23/2021
Name: Zach Guy and Eric Murrow

Zone: Southeast Mountains
Location: Copper Creek
Aspect: West, North West
Elevation: N/ATL

Avalanches: We found sensitive storm slab conditions today at upper elevations. Numerous thin soft slabs released naturally this morning, and we ski cut a handful of similar slabs. All of the slabs were small in size: most were 2″ to 4″ thick, 10 to 20 feet wide. In wind drifted areas, slabs were up to 8″ thick. In sustained steeper terrain, slides ran up to 1500 vertical feet.
Weather: Pulses of moderate to heavy snowfall between periods of quiet weather. Some moderate gusts with wind transport at higher elevations.
Snowpack: About 3″ of new since yesterday.

Date of Observation: 04/17/2021
Name: billy barr

Zone: Southeast Mountains
Location: Gothic

Weather: Cloudy with light snow overnight with 2″ new and water a light 0.12″ on top of a frozen snowpack. Wind is calm and the snowpack back up to 27″. Currently only a few flakes of snow and clouds look to be thinning with a low of 18ºF after a high yesterday of 38.

One inch on top of one inch is better than no inch on an inch.

CBAC 2020-21 Observations

Date of Observation: 04/16/2021
Name: Kinler, Murrow, Ross

Zone: Northwest Mountains
Location: Axtell
Aspect: North
Elevation: 9,500-11,800ft

Weather: Party Cloudy, calm winds, and a few falling flakes.

Snowpack: Another inch of new snow. Steep due north was still skiing well. A little funk here or there with old crusts. Small skier triggered sluffs in steep terrain. Sticky snow surfaces down low. The previous winds from yesterday and last night made the more alpine features look uninspiring with wind-board or firmer looking snow surfaces. We chose to ski where the snow surface was protected from those winds.
