FORT GARLAND, Colo. — Three people have been arrested for allegedly starting a Colorado wildfire by leaving a campfire unattended.

The Teller County sheriff’s office said Monday that 23-year-old David Renfrow, 19-year-old Kegan Owens, and a 17-year-old boy were arrested in connection with a fire east of Fort Garland that has destroyed at least eight homes.

The Chateau Fire in the state’s south central mountains has burned about two square miles, but all residents have been allowed to return home.

It is one of 10 large wildfires in Colorado. The largest, the Spring Creek Fire, has destroyed more than 130 homes and is 70 percent contained.

A fire pit that wasn’t completely extinguished is suspected of starting that 168-square-mile fire.

In a separate development, crews have gained some ground against a deadly wildfire burning on the California-Oregon state line that killed a man and injured three firefighters.

California fire officials say the Klamathon Fire was 30 percent contained Monday.

The fire, one of many in the drought-ridden West, killed one person in a house and destroyed 72 structures.

It also injured three firefighters, including one who suffered severe burns to his face.
