Snowpack Summary
Snowpack depths are highly variable across the region, with elevation, and in wind-exposed areas. Recent cold and clear weather has resulted in surface hoar formation and near-surface faceting, which is now getting buried by light dry snow. Low-elevation and wind-affected areas have a shallow faceted snowpack. While in higher elevation sheltered areas the previous storm snow is settling and gaining strength; however, weaknesses at the old snow interface down approximately 40cm may still exist. The lower snowpack is a series of crusts, some of which are laminated with facets, particularly in shallower areas.
