VIDEO: Dust devil forms during controlled burn in Denver

DENVER (WITI) -- Firefighters out west conduct controlled burns this time of year to minimize the risk from wildfires later in the season. But during a controlled burn near Denver, something unusual happened.

Thomas Rogers was shooting video when a large whirlwind of tumbleweeds blew up 200 feet in the air during the controlled burn at the Rocky Mountain Arsenal National Wildlife Refuge on March 14th.

“You don’t see that very often,” a firefighter says on the video.

The “fire-whirl” didn’t get too far out of control and it didn’t cause any damage. It was just a wild sight caught on camera until the wind died down.
