Date of Observation: 12/28/2021
Name: Zach Guy and Evan Ross
Zone: Northwest Mountains
Route Description: Quick afternoon snowmobile tour out to look at 7 sisters and back, testing some small slopes enroute
Observed avalanche activity: No
Avalanches: Poor visibility. 7 sisters stayed put. Couldn’t see much else for avalanche terrain.
Weather: Moderate snowfall all afternoon, light winds in valley location.
Snowpack: Deep, unconsolidated snowpack; about 5 feet down to persistent weak layers. Boot pen is about 4 feet. We slope cut a handful of low elevation, south facing test slopes with no cracking or signs of instability. We got one large collapse on a low angle, shady aspect while Evan and I were both wrestling with his stuck snowmobile (see photo). The wrestle-your-snowmobile-unstuck test did not produce any results on southerly facing, below treeline slope, despite numerous tests in various locations.

- The one collapse of the day: A shady low angle slope, while we were both wrestling Evan’s sled which had tunneled close to the ground.
