Slabs On Junk

CB Avalanche Center 2020-21 Observations

Zone: Southeast Mountains
Date of Observation: 12/12/2020
Name: Colorado Backcountry AVY L1
Aspect: North East
Elevation: 10,000

Avalanches: 1 Tree Bomb triggered D1

Weather: Overcast, calm, cold. Mostly light snowfall with about 2″ new snow on the cars when we returned to the trailhead.

Snowpack: About a 35cm soft slab, sitting on exceptionally weak facets. When we tried to isolate columns, with hands or ski poles, the columns failed before they were fully isolated. We never felt any collapses, but traveling in areas with slope angles between about 15 to 30 degrees, often produced shooting cracks and blocks of new snow shifting on the facets below.
