Avalanche Summary

Expect human triggered and natural avalanches to occur in steep, wind-affected terrain at higher elevations.

Snowpack Summary

30-40 cm of new snow now overlies a crust. Indications are the new snow has generally bonded well at elevations below 1500 m. Higher up things are uncertain - we basically have no reports. Travel in many places is rugged, with many open creeks, alder and other early season hazards. Expect snow depths of around 10 cm at 800 m and around 120 cm at 1200 m.
