Avalanche Summary

There have been no recent avalanches reported in the region. If you are getting out into the mountains, let us know what you see by posting to the Mountain Information Network!

Snowpack Summary

Ongoing strong westerly winds have likely been creating wind slabs at upper elevations on lee terrain features. Snowpack depths are highly variable this early in the season with amounts ranging between 50-100 cm at higher elevations, and tapering rapidly below treeline (check out this MIN report from Imperial Ridge). A crust has been reported in the middle of the snowpack.
