Generally stable avalanche conditions; however, it is still early season and many alpine features still contain many thin/ weak spots. Watch out for isolated wind effect in the alpine. Merry Christmas! IJ

Snowpack Summary

A storm on December 23 dropped between 15 to 30 cm of low density snow over the forecast region. Generally very little wind effect in storm snow, but some soft slabs have developed near ridge tops. The Nov. 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

No new avalanches observed today.
