Benton County firefighters fought to contain a range fire late Sunday afternoon off Interstate 82, between Coffin Road and McNary Dam.
The fire was fueled by high winds and required almost 15 fire trucks and water vehicles to be called to fight the blaze, said A.J. Hill, fire coordinator for Benton County.
Firefighters had about 80 percent of the fire contained by 9 p.m., but various hot spots kept them busy later into the evening, Hill said.
No road closures or structures were threatened by the blaze.
Never miss a local story.
Cause of the fire remains unknown.
