Avalanche Summary

No new reports of avalanches over the past few days. 

Thanks to everyone who has submitted a MIN report over the last few days!

Snowpack Summary

Recent north wins could have begun redistributing snow back on to south facing slopes.

Previous strong southerly winds combined with snow created wind slab on all exposed terrain on north aspects. These wind slabs are generally now well bonded to the surface below but rider triggering could still be possible in specific areas near ridge crests. South aspects are a mix of scoured and pressed surfaces. 

Soft snow can still be found in sheltered features and at lower elevations.

In shallow snowpack areas a layer of loose facets sits at the bottom of the snowpack.

Terrain and Travel

  • Use ridges or ribs to avoid areas of wind loaded snow.
  • Recent wind has varied in direction so watch for wind slabs on all aspects.
