Ever wonder how the Wyoming Department of Transportation helps reduce avalanche danger on mountain passes during the winter? They bust out the big guns.

WYDOT is one of many agencies across the world who create their own "controlled avalanches" using heavy artillery.

In their case, WYDOT crews blast shells from a M101 Howitzer into potentially hazardous snow drifts.

If you think it sounds cool, just wait until you see the World War II era cannon in action.
