Mitchell, OR -

A sheriff says a wildfire burning in central Oregon has prompted the evacuation of numerous campgrounds and roughly a dozen ranch homes.

Wheeler County Sheriff Chris Humphreys said late Monday night that the Bailey Butte fire has burned across about 800 acres in an area where the Ochoco National Forest meets rangeland. He says local fire departments are protecting homes and so far no residences have burned.

A two-mile stretch of U.S. Highway 26 was temporarily closed about 13 miles west of Mitchell, Oregon. The Red Cross says it plans to open an evacuation center in Mitchell.

The sheriff says another fire in the area, Toney Butte, has burned across 2,000 acres but hasn't prompted any evacuations.

He says the area has been hit by lots of lightning but it wasn't immediately clear what started the fires.
