Avalanche Summary

No new avalanches observed in the last 4 days due to no field work.

Snowpack Summary

15cm of storm snow being redistributed by moderate SW winds into a new slab. This overlies wind-affected old surfaces and pockets of windslab in the alpine and at treeline. The lower snowpack is a variety of old surfaces including facets, crusts, and windslab. A spotty crust exists at the very bottom of the snowpack in deeper locations.

Below treeline new snow sits upon 20cm of settling storm snow. This overlies early-season snow in the form of facets and crusts
