Avalanche Summary

Today's road patrol did not see any new avalanches.

Sunday's Icefield team noted numerous loose dry avalanches up to size 1.5. One size two slab avalanche was observed in the fan of a couloir on Snowdome.

Snowpack Summary

The Icefields received up to 40cm of new snow November 22-23. Moderate southwesterly winds have created windslabs above treeline. The mid pack generally consists of firm windpressed snow from earlier wind events. Snow cover in the alpine varies greatly, with some areas blown free of snow, while other areas are filled in. The weather station near the Parkers parking area has a snow depth of 110cm while 60cm sits in the Bald Hills.
