Boom! Wait, you have a cannon?

My friends at the Washington State Department of Transportation posted this photo on their Flickr feed recently. Amazing how a photo can offer a glimpse into the world of transportation.

FIRE!

From WSDOT: “Avalanche Specialist Alan Willard yells “FIRE!” as he shoots a howitzer. Crews are working to reduced avalanche hazard near SR 20 at Liberty Bell. The successful mission knocked down 8 feet of snow covering both lanes of the highway.”
