Gothic natural and some skier triggered slabs

CBACCBAC Observations

Date of Observation: 12/29/2022
Name: Zach Guy

Zone: Southeast Mountains
Route Description: Rec tour on Anthracite Mesa, traveling on various aspects to 10,800′

Observed avalanche activity: Yes
Avalanches: Large natural slab avalanche likely ran this morning on a southwest facing slope of Gothic, to the ground. Skier triggered a couple of thin soft slabs that failed within the storm snow on lightly cross-drifted southerly terrain. Had decent vis of the Lower Slate from Birthday Bowl on Skooks to Happy Chutes and only saw a handful of loose dry avalanches.
Weather: Very light snowfall. Light winds with occasional moderate gusts causing brief periods of blowing snow. Cold temps.
Snowpack: 35 to 40 cm of F to F+ snow down to our most recent facet (1mm) and crust/facet layers. This interface produced only minor cracking and non-propagating results in quick tests. No signs of buried surface hoar here. In lightly wind-drifted terrain exposed to down valley winds, we produced shooting cracks and triggered a couple of soft slabs breaking on precip particles within the storm snow, up to 25 cm thick or so. One was remotely triggered from 20 meters away.
