The best riding can be found in sheltered terrain.

Avalanche Summary

No new avalanches were reported at the time of publishing on Thursday.

On Tuesday, the sun triggered several wet loose avalanches (up to size 2) in steep south-facing terrain.

Two large, explosive-triggered avalanches (size 2 and 3) were reported on Monday in the region's south. Both avalanches occurred at treeline on southeast slopes. They failed on sugary facets down 30 to 50 cm.

Snowpack Summary

15 to 30 cm of recent snowfall continues to be redistributed by southwest wind. There is a layer of sugary facets that are buried 30-50 cm deep and in some places sits on a crust from December.

The lower snowpack contains a series of crusts and faceted snow that have been unreactive so far. Expect snow depth at treeline to be 100 to 150 cm.

Terrain and Travel Advice

  • Avoid lee and cross-loaded terrain.
  • Seek out sheltered terrain where new snow hasn't been wind-affected.
  • Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.
