Date of Observation: 12/04/2022
Name: Zach Guy
Zone: Northwest Mountains
Route Description: Baxter Basin and Cascade Mtn, Traveled on various aspects up to 11700′
Observed avalanche activity: Yes
Avalanches: Numerous natural D1.5 to D2 slabs from the last storm, most on North to East N/ATL, with a couple that rounded to Southeast and South-Southeast aspects. Light was flat so it was hard to make out exact sizes and crown connectivity. See photos. Tried getting some smaller terrain features to release without any luck.
Weather: Clouds increased mid-morning. Light winds with light transport at times. Mild temps.
Snowpack: Frequent collapses, some localized, some rumbling across entire terrain features. Slabs are generally 2 feet thick and average 4F hard over our well-advertised weak layers. We targeted a pit on a due south slope that held old snow prior to the recent storms. The crust capping the large-grained facets is about 6 cm thick, and tests did not propagate.
