Comments
Interesting day. My intent was to dig a full pit to identify two persisitnat weak layers. PWL's were idnetified at 109cm from ground and 70cm from ground. Both layers were unreactive. The suprizing result came from an CTV SC Q1 (10cm) the basal facets are still reactive. It is also worth noting that I had and ECTX which may have been due to possible shrub interferance. The shovel sheer after the ECT was very easy and broke easly at the ground. Upon completing my pit and moving down the ridgline I triggered a few small cornaces that produced two SS-AC-R2/D1-I Avalanches. It was evident that wind slabs continue to be our primary concern however I can certaily see how a wind slab avalanche could trigger persitant weak layers deper in the snow pack.
