Avalanche Summary

On Thursday and Friday, wind slabs up to size 1.5 were reported to be reactive to human triggers on all aspects at treeline and in the alpine. These wind slabs failed on older firm surfaces and facets approximately 20-50 cm down.

Snowpack Summary

10-20 cm of low density snow now sits over a variety of old surfaces including firm wind affected snow, sun crusts on steep solar aspects and surface hoar and faceted crystals in sheltered areas. Strong northeast wind from earlier this week formed pockets of wind slab in exposed terrain. In some instances wind slabs have been reported to be failing on a sugary faceted layer down 20-50 cm.The lower snowpack is generally well-settled.
