Smoke from the Wallow Wildfire billows over the White Mountains as the sun sets in Springerville, Arizona June 8, 2011. The wildfire, believed to be sparked by inattentive campers, blazed unchecked for an 11th day in eastern Arizona on Wednesday, leaving at least 600 square miles of pine forest blackened and menacing several mountain towns near the New Mexico border.
