Weather
10" of new snow at the highway stake, very low density. Mostly clear skies and mild temps with light SW winds gave way to increasing clouds and overcast skies by late afternoon. Snowdepths; 46" at the highway stake, 32" at Snotel, 20" at the old highway stake.
Snowpack
Mostly facets of one sort or another. No signs of cracking or collapsing. When sufficient slab arrives the danger will increase.
