Lo esencial

Wind slabs have made travel challenging at tree line and above. Some better skiing/riding can be had in sheltered treed areas and lower angled terrain.

    The buried wind slab will be hard to trigger but if you are able to get it to go from a thin area, it could produce a large avalanche. Thin wind slabs are also being found along ridgelines.

Avalanche Summary

No new reported or observed today

Snowpack Summary

Extensive wind slabs, hard wind slabs, buried wind slabs, and sastrugi(wavy ridges of snow formed by the wind) dominate the alpine and open areas of tree line. These hard wind slabs can be tricky to evaluate because they have the potential to propagate but gives someone the impression underfoot that the base is solid. Take the time to dig and evaluate before committing to larger slopes.

Terrain and Travel

  • Watch for areas of hard wind slab on alpine features.
  • Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
