Date of Observation: 01/31/2021
Name: Ben Pritchett
Zone: Northwest Mountains
Location: Views in around the West Elks, Ruby Range, and Elk Range.
Avalanches: Lots of avalanche activity up-valley from Crested Butte. Kebler Pass, Ruby Range, and the main Elk Mountains all went through a cycle of mostly D2 avalanches. East to southeast near and below treeline had the most number of avalanches. Many of these avalanches near and below treeline broke broadly, and generally deeper in the snowpack, failing on buried persistent weak layers. Some of these released as late in the day as 3:30pm on east-facing terrain. Above treeline many slides released in the storm snow earlier in the loading event (January 30) on north through northeast to east-facing slopes. These had softer, lightly filled in crowns and were mostly small relative to the paths though some were D2’s in destructive size.
