Aerial searchers look for possible missing hikers near CA wildfire LOS ANGELES, May 31 (UPI) -- A wildfire that scorched about 1,000 acres in Los Angeles County by Thursday afternoon prompted an aerial search for possible missing hikers, authorities said. The county fire department said it dispatched a helicopter to fly over an area near the brush fire in the Angeles National Forest north of Castaic after a report that as many as nine hikers may have been missing, the Los Angeles Times reported. A department spokesman said one hiker was spotted Thursday evening but was not in danger, the newspaper said. The Powerhouse fire, which was being fanned by winds gusting up to 24 mph, was burning close to high-voltage power lines, but no power outages had been reported. The Times reported the county sheriff's department said mandatory evacuations were ordered in the Green Valley area. At least one structure owned by the Los Angeles Department of Water and Power was destroyed by the blaze, which was being fought with water-dropping aircraft as well as by firefighters on the ground.
