Comments

Ski tour and stability evaluation with Level 3 course in Grizzly today. Seems that new snow instability is rapidly gaining strength as the storm exits but the wind slabs were still touchy and reactive. This was an intentional ski cut on a small terrain feature with very low consequences. There was evidence of a previous group triggering a similar pocket just a little higher up. We also observed a large slide on Doug's Drop in Silver Fork. Lots of snow moving around on the upper ridges and peaks in various directions that could be problematic tomorrow. Most evidence of avalanche during the storm came from observing partially covered debris piles then seeking out the blown in crowns. Pics are the small pocket I triggered, Dougs and Culps.
