Snowpack Summary
New snow is burying largely variable crusty and wind-affected snow surfaces at all elevations and on all aspects. New snow may sit atop weak surface hoar crystals in wind-sheltered terrain at treeline.
A surface hoar layer may be found down 20 - 60 cm in isolated north-facing terrain features.
Below 1500 m, a thick melt-freeze crust is buried 50 - 100 cm deep.
