Points saillants

Time to start asking for snow this Christmas! Any avalanche will likely involve the entire snowpack. Great climbing conditions in areas such as the Ghost.

    Windslabs are common in alpine areas. Watch for this areas around the "lens" of windslabs where it will be more likely to trigger this weakness. Any failure will likely step down and involve the entire winters snowpack.

    If triggered the surface wind slabs may step down to this layer and involve the entire winters snowpack.

Avalanche Summary

No new avalanches were observed.

Snowpack Summary

Wind slabs are common in the alpine and are more sensitive to triggering along lee features, convex rolls along ridges and cross loaded gullies. The height of the snowpack varies significantly and where it is deeper, the snowpack is generally stronger. The October crust is located in the bottom 20cm of the snowpack and the November crust is not as widespread and is found about 35cm off the ground. Take the time to dig and investigate these layers.

The Dec 7th interface is found on most aspects up to 2200m and on more solar aspects up to 2500m.

Terrain and Travel Advice

  • If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.
  • Avoid steep terrain that is rocky and thin.
