Snowpack Summary

30-40 cm of new snow has buried a wide variety of old snow surfaces including stiff wind slab or wind effected snow at upper elevations, sun crust on steep southerly slopes, surface hoar and surface facets in sheltered locations. An additional 15-20 cm is expected by Sunday morning, bringing storm totals to 40-60 cm. The mid-January interface (facets) is buried approximately 60-100 cm down and recent snowpack tests have shown hard, yet sudden planar results. The mid and lower snowpack is generally well settled (strong). However, there remain a number of facet and crust layers that are currently dormant but will require monitoring with additional loading.
