The new year's day wind event did a lot of re-sculpting of the snowpack in this area.
Clear, cold, and calm. Usually don't get all three of those in the Pioneers.
We looked at the very large avalanche that was remotely triggered by a skier the previous day. It involved a very dense slab that failed on a layer of 2-3mm DH. The snowpack stratigraphy was not intact here, but it seems that this layer is likely 11/27. DH was large, crisp, striated, and chaining in places. This slide broke quite wide, pulling back into relatively shallow terrain. It augered down to the ground in much of the bed surface.
