Update 9:12 p.m.: Hikers walked out on their own
Hikers feared missing in the area of the Powerhouse Fire were spotted walking out on their own and apparently in good condition, according to the L.A. County Sheriff's Department.
"In about the last half hour several hikers have been spotted and they are clear of that evacuation area," said Sgt. Brian Dorsey of the Palmdale station. "As of right now we don't have any further information as to additional hikers that are outstanding. The last set of hikers that came through actually stated that they believed they were the last ones on the trail."

Some 300 firefighters from Los Angeles National Forest and L.A. County had been deployed to help combat the fire, which had consumed more than 1,000 acres since it was first observed at 3:28 p.m., Angeles National Forest spokesman John Wagner said.
