Nature is an unpredictable beast.
That's the lesson a Colorado fire crew learned when things suddenly went in an unexpected direction during a prescribed burn at the Rocky Mountain Arsenal.
Prescribed, or controlled, burns are a necessary part of keeping a forest healthy as they clear out overgrown vegetation that would otherwise raise the risk of a much larger wildfire, but it's rare that they would have quite this effect.
Thankfully, the well-trained crew contained the fire, tumbleweeds and the dust devil, managing to only burn one acre of land they hadn't planned to.
The video, posted by Thomas Rogers, gives a pretty remarkable first-hand perspective of this incredible natural phenomenon.
