Avalanche Summary

No new avalanches have been reported in the past few days, but field observations are very limited.

If you are going out in the backcountry, please consider filling out a Mountain Information Network (MIN) report.

Terrain and Travel Advice

  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Watch for signs of instability like whumpfing, hollow sounds, shooting cracks, or recent avalanches.
