Avalanche Summary
No recent avalanche activity has been reported.
Observations remain limited this early in the season. If you head into the backcountry, please post to the Mountain Information Network
Snowpack Summary
Wind-affected surfaces exist in exposed terrain at upper elevations. While 30 to 40 cm of settling snow can still be found in wind-sheltered terrain.
Down roughly 40 to 90 cm from the surface at treeline, a crust buried in early November exists. Reports suggest that weak faceted crystals or surface hoar may exist on top of the crust in some areas.
Various melt-freeze crusts can be found at the base of the snowpack, which are not concerning avalanche layers at the moment.
Snow depths at treeline are roughly 80 to 150 cm, and decrease rapidly at lower elevations..
