Five active wildfires — the Lee, Elk, Oak, Stoner Mesa and Crosho fires — have charred more than 142,000 acres, or 222 square miles, on the Western Slope in recent days.

At least 15 fires have burned more than 198,000 acres across Delta, Dolores, Garfield, Grand, Mesa, Moffat, Montrose, and Rio Blanco counties, as well as in parts of eastern Utah.

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.
