Last week's storm resulted in slabs at higher elevations (above 2000 m) where snow remained dry. At treeline and below (2000 m and lower) the snowpack has a frozen crust on the surface.
The mid-snowpack is well-settled. The lower snowpack consists of several crusts with weak faceted crystals above and below that are beginning to heal and bond to each other.
Snowpack depths are roughly 150 cm cm at treeline and tapers rapidly below 1500 m. This is about 60 - 70% of average.
