Numerous 0.5 - 1.5 avalanches observed on N & SW aspects. Observations taken from the 1900m shoulder, N of Rohr lake. Most debris piles looked size 0.5-1 (small pockets from convex or cross loaded features). Start zones of the three size 1.5-2 debris piles were not observed due to clouds. Avalanches ran mid storm cycle.
