Highlights

Good powder for skiing. Watch for localized slabs sitting over the Oct. 26 crust and facets. It is still possible to trigger large avalanches in more aggressive terrain.

    This problem can be found up to 2800m mainly on shady aspects. We haven't seen much in the way of avy activity over the last few days, with the exception being some sobering explosive controlled avalanches at the ski hills (see avalanche table).

Weather Forecast

Clear and cold for a few days. 

Snowpack Summary

25-40cm of recent snow with variable wind effect overlies a faceted snowpack 60-80 cm deep at treeline and up to 150cm on the Icefields. The Oct. 26 crust and facets sit roughly 30 cm above the ground up to 2800m on shady aspects, and above 2800m on solar aspects. This crust has been dormant recently, producing only hard results in field tests.
