In wind sheltered terrain, last week's storm snow, up to 10" deep, is quickly losing cohesion due to faceting. In this type of terrain, there were no slab avalanche concerns but some minor sluffing running on the Thanksgiving rain crust. There were small pockets of wind slab near ridgelines that didn't produce any signs of instability with a little prodding. The big news is rampant surface hoar and near surface facet growth; all but the most wind battered slopes will have a troublesome weak layer/crust combo going into our next storm....whenever that is.
Up Ninko Creek to the summit of Mt. Thompson-Seton
Skier triggered one harmless facet sluff entraining the top 8" of faceted snow above the Thanksgiving crust.
