Points saillants

Start on small slopes and watch for signs of reactive wind slabs before committing to steeper or more complex terrain.

    Wind slabs may be starting to bond to the rest of the snowpack, but terrain below ridgecrests and in cross-loaded features remains the most likely place to trigger an avalanche.

Confidence

Moderate

  • We are uncertain due to a limited number of field observations.

Avalanche Summary

No recent avalanches have been reported.

If you are heading into the backcountry, please share any observations with the Mountain Information Network.

Snowpack Summary

25 to 50 cm of settling or wind affected snow overlies old wind-affected surfaces, crusts, or strong, settled snow.

The remainder of the snowpack is consolidated with no layers of concern.

Terrain and Travel Advice

  • Start with simple terrain and gather information before committing to bigger features.
  • Be careful as you transition into wind-affected terrain.
  • Look for signs of instability: whumphing, hollow sounds, shooting cracks, and recent avalanches.
