Firefighter Al Fix of Missoula, Mont., leans against a pine tree to get a little sleep along the firebreak in Icicle Canyon near Leavenworth, Wash., early Wednesday. A thunderstorm that had threatened to kick up old wildfires and touch off new ones instead brought much-needed relief to the dry slopes of the eastern Cascades Wednesday and gave crews the chance to strengthen and extend firebreaks. More than 9,000 firefighters were battling seven major blazes in Washington. No serious injuries have been reported among firefighters, but at least 37 homes have burned. But lightning started new fires in eastern Oregon, including one that ultimately covered 34,000 acres of rangeland in the Bureau of Land Management's Vale District. The Fire Center said crews were battling 19 major fires in six states Wednesday.
