Denver, Colorado -
(KUSA) A 150 acre, prescribed burn near the Rocky Mountain Arsenal grew out of control when a massive dust devil swept fire and tumble weeds in the firefighters direction.
The prescribed burn happened around noon, Friday, March 14.
Video captures the moment the dust devil began and shows hundreds of tumble weeds catching fire before several firefighters run for safety. From a safe distance, the filming resumes.
The unexpected dust devil ended up burning an extra acre of land but no property was damaged and no one was injured.
