Weather: Sunny, calm winds. Notable temperature inversion around 4500' or so.
Snowpack: Average HS between 30 and 70cm. Some ridgelines are scoured to ground. Snowpack mostly consists of 4F and F facets and depth hoar. Solar aspects had developed a strong sun crust which was softening midday. Isolated areas near ridgetops had P windslab, mostly W-NW. Hand shears and ECT showed low cohesion facets, with lack of slab structure in sites tested.
Area Description: Blewett Pass-Tronson Ridge-Diamond Head
