Avalanche Summary

A few very small loose dry sluffs were reported by the field team last Wednesday in steep shady terrain. No significant avalanches have been reported since last weekend.

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 total alpine snowpack depth around White Pass is around 180 cm deep.

Terrain and Travel Advice

  • Make observations and continually assess conditions as you travel.
  • 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.
