Snowpack Summary

40-60 cm of new snow now overlies a crust at treeline elevations. 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, although things should be improving with recent new snow. Expect snow depths of around 20 cm at 800 m and around 140 cm at 1200 m.
