Communities in the U.S. West and Canada are under siege from raging wildfires. A blaze sparked by lightning is moving fast in rural Idaho and a human-caused inferno has forced the evacuation of hundreds of homes in northern California. Authorities said a tanker plane crashed in Oregon while fighting one of the many wildfires. A single pilot was on board and was found dead on Friday. California's largest active wildfire is zero percent contained after destroying 134 structures and threatening 4,200 more. A California sheriff says the Park Fire was started when a man pushed a burning car into a gully in Chico.
