Avalanche Summary

There are no recent avalanche observations to report at this time.

Snowpack Summary

10-20cm of new low density snow has been lightly redistributed by the wind creating wind slabs in isolated locations and burying a small layer of surface hoar or facets. These are sitting on a generally well-settled mid-pack. Deep persistent instabilities (surface hoar and an early November crust, respectively) located in the middle and near the bottom of the snowpack may still be a concern but there's little recent evidence of them being reactive. It is important to know that we have very limited observations for this region. Digging down and making your own observations, especially in thinner snowpack areas, remains a good idea to assist safe slope selection. If you are spending anytime in the backcountry, send us your observations. Every bit is greatly appreciated! Email us at: forecaster@avalanche.ca
