 Despite an aggressive response from multiple agencies, high winds spread the fire to over 15,000 acres within the first 24 hours. The fire has now burned more than 17,000 acres and is nearly 90% contained. The cause of the nearby salt fire remains under investigation, with the FBI offering a $10,000 reward for information leading to the arrest and conviction of anyone responsible for that fire.
