#m101a1

No, the State of Colorado isn’t blowing up grandmas for doing 10 mph under the limit in the left lane. But the state’s Department of Transportation is keeping people safe by clearing avalanches with World War II artillery.

Armed with a 105 mm howitzer — possibly an M101A1, though please feel free to correct us — the Colorado DOT clears avalanche prone areas by shooting shells up to 7 miles away into the mountain tops. Those shells have a secondary charge that explodes on impact to trigger a controlled avalanche.
