Snowpack Summary
Variable conditions exist at all elevations, including crusty and wind-affected snow. Soft snow and good riding can still be found in sheltered north-facing terrain. New surface hoar has formed at treeline.
A layer of surface hoar may be found down 20 - 60 cm in isolated north-facing terrain features.
A thick melt-freeze crust is buried 50 - 100 cm and exists below 1500 m.
