Avalanche Summary

No new avalanches have been reported for several days; however, observations are very limited.

Snowpack Summary

Up to 5cm new snow now covers a fairly widespread surface hoar layer. Below this 5-15 cm of dry faceted snow sits on a variety of old surfaces including a melt-freeze crust on solar aspects in the alpine, and surface hoar in sheltered areas at treeline and lower elevations. Overall, the snowpack is still quite shallow and weak throughout the region.
