Comments
Snow had a total depth of 52" on this north aspect the ECT failed at 4 with top layer of new snow failing on a very thin layer of facets/buried surface hore. Then the rest of the column failing at 25. The center of thre pack is very well bonded and solid making the snow feel more stable then it is. We experienced womping cracking and collapsing through the day. As well as one small slide that had the top layer fail naturally.
