Officials in Routt County say hotshot crews from Wyoming and two helicopters are helping fight the blaze, which is burning in prime elk habitat.

A second nearby blaze, the Big Red Fire, has burned about 2 square miles (6 square kilometers) near the Wyoming border. It started Aug. 19 but has spread in the past few days in hot, dry weather.

Smoke from those two wildfires and others burning in the Pacific Northwest has created unhealthy air quality across western Colorado. It’s also obscured the view of the mountains from Denver and the Front Range.
