Classic Post: Washington State Uses M-60 TANKS for Avalanche Control Work

Washington State Use TANKS for Avalanche Control

The Washington State Department of Transportation uses several methods to protect drivers from avalanches along US 2 near Stevens Pass, including firing live artillery rounds at unstable snow to trigger avalanches while the roads are clear. Avalanche technicians usually fire the two M60 tanks near the summit at Stevens Pass between midnight and 6 a.m., but on Tuesday, January 09, 2013, WSDOT officials decided that the snow was unstable enough that US 2 needed to be shut down during the afternoon so that avalanche technicians could fire the tanks.
