Snowpack Summary

Warm weather has melted the snow surface to the top of the highest mountains, particularly on southerly aspects. Surface crusts may form overnight but will melt quickly in the morning with sunny skies. The upper snowpack is well-settled and bonding to a buried crust. Below treeline there are still open creeks, alder, and other early-season hazards. Expect snow depths around 200 cm at 1300 m and 60 cm at 800 m.
