Idaho 21 Avalanche Digout

Obviously Highway 21 is outside of our region but I saw these pics and wanted to share them just cause they demonstrate what could happen on Snoqualmie and other Washington passes.

This is Idaho 21, known as "Avalanche Alley." It reopened yesterday after a nearly weeklong closure due to- well- avalanches.

The 12-mile stretch  between Grandjean Junction and Banner Summit got 25 inches of additional snow during the closure, while crews tried to clean up the already-deep snow, which was strewn with rocks and timber.

Avalanche Alley has about 60 avalanche chutes. You can see more pictures here.
