Tornadoes of flame caught on camera

EUGENE, Ore. - Firefighters in Oregon and Colorado this week captured video footage of "fire whirls," also known as fire devils or fire tornadoes.

Fire whirls are a "spinning vortex column of ascending hot air and gases rising from a fire and carrying aloft smoke, debris, and flame," according to the National Interagency Fire Center in Boise, Idaho. "Fire whirls range in size from less than one foot to over 500 feet in diameter. Large fire whirls have the intensity of a small tornado."

The Oregon example happened Friday, August 12, in a field that caught fire near NW Cornelius Schefflin Road and NW Verboort Road. Firefighters from the Cornelius Fire Department captured the whirl on camera.

Charles "Trey" Bolt captured a fire whirl on camera in Colorado on Sunday, August 14, while working the Beaver Creek Fire near the Wyoming border.

The official Beaver Creek Fire information Facebook page initially posted a still photo of the "firenado" on Monday.

The image took off like wildfire online.

The managers of the page on Tuesday posted a video Bolt made of the fire whirl.

The Beaver Creek Fire on the Colorado/Wyoming border broke out June 19, 2016. Since then, the fire has burned nearly 57 square miles. The fire is 44 percent contained.

The Cornelius fire burned 7 acres and closed roads in the area.
