Firefighters are battling wildland fire that has burned about 100 acres in the area of Smartsville in Yuba County.
Chelsea Fox, a spokeswoman for the California Department of Forestry and Fire Protection, said the fire, which is 70 percent contained, is in a sparsely populated area of Chuck Yeager and Waldo roads. She described the terrain as grasslands and rolling hills.
Some road closures are in effect in the area, but no residences are threatened.
Fox said approximately 100 firefighters are on scene, along with five air tankers and two helicopters.
