Tested NE persistent slab

CB Avalanche CenterCBAC Observations

Date of Observation: 12/19/2021
Name: Bud Tymczyszyn

Zone: Northwest Mountains
Route Description: Red Lady Glades from Kebler TH.

Observed avalanche activity: No
Avalanches:
Weather: Clear and cold, -7 — mid 20s
Snowpack: Dug a pit off the skin-track at 10,400 NE 28deg slope. Got a collapse while digging, and a propagating test result on the basal facets.  ECTP14SC at 23cm.

Also dug a pit to look at snowpack structure on a SSE aspect at 11,400ft. Only potential area of concern was a soft slab resting on a 1cm crust down about 20cm. Didn’t get a propagating result at this interface and saw no signs of instability on a nearby wind-loaded test slope.

We primarily traveled on southerly facing terrain with no other signs to instability. Snow surfaces stayed cold on these lower angled slopes.
