The fire burned about 20 acres of grass and timber, Brown said. Most volunteer fire agencies in the area were fighting the blaze. The fire was burning under Bonneville Power Administration towers, making it difficult for crews to receive aerial support since water couldn't be dropped on the towers, Brown said.

The fire was burning near some structures, but no structures were been lost, according to Brown. He also said no one was injured.

Brown says about 75 firefighters will continue overnight into Friday to extinguish the fire.
