(N.Morgan) In a controlled burn, sometimes ting can go awry and in the video below, you see one way that can happen. This fiery dust devil at the Rocky Mountain Arsenal began as a planned burn, but quickly got out of control when a dust devil swept the fire in with hundreds of tumble weeds!
A dust devil is a strong, well-formed, and relatively long-lived whirlwind, ranging from small (half a meter wide and a few meters tall) to large (more than 10 meters wide and more than 1000 meters tall). The primary vertical motion is upward. Dust devils are usually harmless, but can on rare occasions grow large enough to pose a threat to both people and property.
