Wind gusts and heavy brush created enormous walls of flame and embers sparked spot fires, but crews later were able to make progress in efforts to surround the blaze..
About 450 firefighters from the city, county and U.S. Forest Service were on scene as aircraft dumped thousands of gallons of water.
A firefighter and a jail inmate helping battle the fire were slightly injured. The cause of the fire remains under investigation.
"We've got five investigators at the point of origin right now," Tripp said. "We're going to try to do our best to determine what the cause was."
