Avalanche Summary

No recent avalanches have been reported, but we suspect rider-triggered wind slabs may be possible in the alpine and at treeline on wind-loaded slopes.

Please consider posting a MIN if you are heading out in the backcountry!

Snowpack Summary

Surface snow at treeline and above is variable, with soft snow in sheltered areas and pockets of firm, wind-affected snow in more exposed areas. A supportive melt-freeze crust from mid-November is buried 15–20 cm down and is present up to about 2200 m.

Snow depths at treeline range from roughly 20 to 60 cm.

Below treeline, the snowpack thins significantly—many areas have only a shallow, crusty base or little snow at all.

Be mindful of variable snow conditions and overall snow quality, and watch for classic early-season hazards such as open creeks, rocks, and stumps.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Shooting cracks, whumpfs, and recent avalanches are strong indicators of an unstable snowpack.
  • Be cautious of buried obstacles, especially below treeline.
