Together, five wildfires burning on Colorado’s Western Slope have consumed hundreds of square miles, destroying at least five homes and 19 outbuildings, fire officials said.

As yet another large wildfire grows on the Western Slope, Gov. Jared Polis has declared a disaster emergency statewide and authorized the use of the National Guard. The Crosho fire, which sparked Monday southwest of Steamboat Springs, is now more than 1,700 acres, with no containment.
