Snowpack Summary

A storm on December 23 dropped between 15 to 30 cm of low density snow over the forecast region. There is wind effect in the storm snow at upper elevations and isolated wind slabs have developed near ridge tops. The November rain crust is breaking down but still identifiable in the bottom third of the pack. This layer is producing hard to no shears

Avalanche Summary

Flight to Bow Summit and to Field in good visibility today showed very little in the way of recent natural avalanche activity.
