Avalanche Summary

Several explosives triggered avalanches size 1-2.5 were reported in the region on Saturday. No new natural avalanches were reported on Saturday.Several natural and explosives triggered avalanches to size 2 were reported on Friday.

Snowpack Summary

60-100 cm of recent snow has formed a slab that sits on a weak layer that formed in early December. This layer mostly consists of facets (sugary snow) with some isolated areas also containing small surface hoar (feathery crystals). Several other weak layers have been observed in the lower snowpack such as crusts and facets that formed in late October/early November.
