RIO BLANCO COUNTY, Colo. — The Lee Fire in Rio Blanco County has grown to the sixth largest in Colorado history, according to the Colorado Division of Fire Prevention and Control. The fire was mapped with infrared technology at more than 106,000 acres as of Sunday.

A Colorado prison was evacuated as one of the largest wildfires in state history continued to grow, and officials warned residents of remote areas to be ready to leave Sunday as gusty winds and low humidity fed the flames.

A Colorado prison was evacuated due to a fast-growing wildfire that’s already one of the largest in state history, officials said. The ongoing spread of the Lee Fire in western Colorado forced the relocation of 179 incarcerated individuals at the Rifle Correctional Center to the Buena Vista Correctional Complex on Aug.
