I'm sure the Russian military gave a perfectly good explanation for firing shells at this North Ossessia mountaintop, dislodging an awesome torrent of snow. Probably something to do with a controlled avalanche being preferable to nature's own, etc.
But let's be honest; if you were in the Russian military, stationed out in the mountains, you'd be blowing random stuff up every other hour just to stay entertained. [Buzzfeed]
Update: This is not the first time the Russians have done this! And honestly, how could you stop at just one?
