Avalanche Summary

No new avalanches have been reported since the middle of last week.

Conditions are generally safe, but even small avalanches can have serious consequences on steep features. It's important to stay alert while travelling in avalanche terrain.

Observations have been limited. Please consider sharing your observations through the Mountain Information Network.

Snowpack Summary

5 to 10 cm of wind affected snow sits on a supportive crust. At upper elevations, deeper deposits of wind-loaded snow may exist, up to 30 cm deep.

The remainder of the snowpack is dry, with no current layers of concern. 

The alpine snowpack depth around White Pass is approximately 180 cm, with the depth at treeline measuring around 80 cm.

Terrain and Travel Advice

  • Periods of low danger may be a good time to increase your exposure.
  • Watch for areas of hard wind slab on alpine features.
  • A hard crust on the snow surface will help strengthen the snowpack, but may cause tough travel conditions.
