On Tuesday, a snowshoer in Canal Canyon experienced a significant "WHOOMP" of the snowpack. This is caused by the weak sugar snow near the ground collapsing under the weight of the new snow and the snowshoer acting as a trigger. This was in a flat meadow. Had this been on a steeper slope, it would have avalanched. This is the first significant sign of instability this winter involving old snow and it probably won't be the last, unfortunately.
