Snowpack Summary
20-30 cm of available snow has been redistributed by variable winds into fresh wind slabs on all aspects. This snow covers a crust on solar slopes and a layer of weak surface hoar in shaded terrain.
Buried 50-70 cm deep, a layer of surface hoar, crust, and faceted crystals. Observations are limited in this region but this layer has produced numerous large avalanches in the neighboring regions.
Snowpack depths at upper elevations are around 80-100 cm.
