It's getting tricky to find any good skiing. Where there is snow, backcountry users should be mindful of the consequences of even a small avalanche. The snowpack remains shallow with lots of hidden hazards just waiting to wreck your season.

Avalanche Summary

No new avalanche activity observed or reported.

Snowpack Summary

Alpine areas have been heavily affected by the past week of strong winds and wind slabs are widespread at tree line and above. Ridges and ribs are stripped free of snow while lee and cross-loaded terrain have deep deposits of wind loaded snow. The November crust is down 30-100cm and is producing anywhere from moderate to no results. Moist snow has been seen on steep solar aspects...so expect a surface crust on these slopes.

Terrain and Travel

  • Watch for areas of hard wind slab on alpine features.
  • Approach lee and cross-loaded slopes with caution.
