Date of Observation: 11/30/2022
Name: Zach Kinler
Zone: Southeast Mountains/ Northwest Mountains
Route Description: Slate River TH to the bottom of Purple Palace
Observed avalanche activity: Yes
Avalanches: Documented a widespread cycle of avalanches from the recent storm on East through North aspects at all elevations. There were many small avalanches below treeline and numerous large D2-2.5 avalanches near and above treeline. The majority of these slides appear to have failed on 11/29 with the earlier ones filling back in a bit making them harder to identify.
Weather: Cold, had the handlebar warmers on high.
Snowpack:
-

Several large avalanches, NE aspect of Wolverine Basin

-
Crowns and debris have been filled in but evidence of a large slide on “The Shield” with a couple more lower down near treeline

A few large avalanches on East and NE aspects of Scarp Ridge
