Snowpack Summary
Continued snowfall adds 25 cm more snow overnight in some areas. Accompanying southwest wind will redistribute this new snow, forming deeper deposits on leeward slopes at higher elevations.
Below the new snow, a thick melt-freeze crust exists below approximately 1500 m.
The mid and lower snowpack is generally well-settled and stable.
Snow depths at treeline range from 120 to 180 cm.
