    New snow, accompanied by variable alpine wind, continues to accumulate over a firm crust. Where winds have redistributed new snow look for signs of slab formation.

Avalanche Summary

On Friday a natural size 2 avalanche was reported in the region on a south aspect where recent snow failed on the prevalent crust that formed in early February.

If you head out consider posting to the mountain information network.

Snowpack Summary

Anywhere from 5 to 20 cm of dry snow sits atop a widespread hard crust. In general, the crust is strong and supportive to travel on below 1900 m. Above 1900 m the crust becomes breakable and tappers out entirely around 2300 m.

Below the crust, the upper snowpack continues to refreeze and strengthen.

The mid and lower snowpack consists of various weak layers primarily made up of crust and facet combinations.

Terrain and Travel Advice

  • Carefully evaluate steep lines for wind slabs.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
