5-10 cm of fresh snow (and more expected on Wednesday) accompanied by moderate SW winds have created fresh windslabs in lee alpine terrain. The midpack consists of 25-35 cm of facetted snow overtop of the Nov 8 crust. The lower snowpack consists of facets and depth hoar. Snowpack depths at treeline vary from 60-90 cm with up to 140 cm in lee areas
