California wildfire traps campers in national forest

Three fast-spreading California wildfires sent people fleeing Saturday, with one trapping campers at a reservoir in the Sierra National Forest, as a brutal heat wave pushed temperatures into triple digits in many parts of state. The wildfire burning near Shaver Lake exploded to 56 square miles (145 square kilometers), jumped a river and compromised the only road into the Mammoth Pool Campground, national forest spokesman Dan Tune said. At least 2,000 structures were threatened in the area about 290 miles (467 kilometers) north of Los Angeles, where temperatures in the city's San Fernando Valley reached 117 degrees (47 degrees Celsius).
