Avalanche Summary

There have been no reports of avalanche activity in the past few days.

Snowpack Summary

Around 25 cm of soft snow overlies a relatively well-consolidated mid and lower snowpack with no obvious weak layers. In some locations you may find a 2 cm thick crust below the recent fresh snow. In exposed locations, the fresh snow has been blown into variable-thickness wind slabs, which may pose local hazards, but are not expected to propagate widely in most locations. Snow depths at White Pass average around 150 cm; deeper locations (higher terrain west of the highway) have as much as 200 cm. It's reasonable to expect a thin snowpack with sugary facets in the Wheaton Valley, although we don't yet have any observations to confirm this.

Terrain and Travel

  • Watch for areas of hard wind slab on alpine features.
