Snowpack Summary

10-20 cm of low density snow covers a variety of old surfaces. These include firm wind affected snow (either scoured or hard wind slab) in alpine and treeline terrain as well as sugary faceted snow, sun crusts on steep solar aspects, surface hoar in sheltered areas. The mid and lower snowpack is generally well-settled.
