Skiing near the continental divide has been refreshed with new snow. However high freezing levels will effect ski quality throughout the week.

As snowfall amounts increase we expect to see a wider avalanche cycle.

  • Be careful of loose dry sluffing in steep, confined or exposed terrain.
  • Steep unsupported terrain and slope convexities are the likely locations to awaken the storm slab.

Aspects: All aspects.

Elevations: Alpine, Treeline.
