Avalanche Summary

No recent avalanche activity has been reported.

Snowpack Summary

Roughly 10 to 15 cm of new snow has buried a widespread crust. Strong winds have scoured surfaces down to the crust in most windward-facing terrain while forming deeper deposits of snow in lee terrain.

Currently, no significant concerns exist deeper in the snowpack.
