Date of Observation: 12/09/2021
Name: Mark Robbins

Zone: Northwest Mountains
Route Description: First toured from the bridge past pittsburgh up the sw facing rollers on the ne side of the road, up to 10,500 or so. Snowpack was 10-12 inches of storm snow to grass and rocks and stumps.
Then crossed the creek to go check in on more northerly aspects. Natural avalanche by the residential bridge crossing the creek, see photo1. Toured up to the first flat field and remote triggered a storm slab on the first ledge, from the flats about 30 yards away, see photo2. A little further on, shooting cracks fractured a slope, reaching 30 yards or so, see photo3 and photo4. We stomped around trying to get more activity, and then tucked tail back to the sleds.

Observed avalanche activity: Yes
Weather: Windy and snowy. Maybe 3 inches of accumulation during the 3.5 hours we were out there.
