10webCBAC Observations

Date of Observation: 12/28/2022
Name: Jack Caprio

Zone: Southeast Mountains
Route Description: Snodgrass. Northeast side

Observed avalanche activity: Yes
Avalanches: We skier triggered plenty of loose dry avalanches in the new snow. Some of the loose dry avalanches entrained into old snow.

We intentionally skier triggered 3 soft slab avalanches failing deeper into the snowpack. In both 1st and 2nd bowl, we triggered soft slab avalanches breaking below the new/ old snow interface.

The loose dry avalanches failed on the 12/27 interface, where as the slab avalanches broke 6-8” below the 12/27 interface (see photos).

We remotely triggered a soft slab avalanche off the gothic road-cut on our way out (<D1)
Weather: S-1 snowfall all day. Warm temps. Overcast skies.
Snowpack: 6-9” of new, high density snow. On northeast aspects below treeline, the new snow fell on top of very weak snow surfaces.
