Observations

We covered a lot of terrain and skied most aspects without issue. There was wide spread graupel of varying depth. On some leeward aspects, in constructions, it was up to 20cm deep. Basically all the graupel we saw came with a 5-15cm wind slab on top. While not very cohesive wind slabs yet, I imagine wind and storm slabs will run easily on the graupel weak layer with more loading coming this week.
