The wildfire that blackened 11, 262 acres including a mobile home park in Los Angeles, has been completely out, authorities said on Friday.

Destroyed in the fire's path were more than 600 structures, including some 480 modular homes at the Oakridge Mobile Home Park, along with nine single-family homes, 104 outbuildings and 10 commercial buildings, according to county fire officials.

The cause of the fire was still under investigation, fire officials said.

Investigators have spoken to witnesses about the brush fire, which began last Friday, but were still seeking additional information to assist in the ongoing investigation into what sparked the blaze, said Brian Humphrey of the Los Angeles Fire Department.

The fire was believed to have started in the city's northern foothills, Humphrey said.

"We hope someone who saw or heard something will call with information to assist in determining the cause of this devastating fire," said Jody Noiron, supervisor of the Angeles National Forest.

On Tuesday, residents of the mobile home park were allowed to return to the site, where only 125 homes were left standing.

Although most of the park's residents have been accounted for, police are still trying to track down residents of 16 units.

On Tuesday, President George W. Bush declared Southern California a disaster area, freeing up federal aid to areas ravaged by the wildfires, including Los Angeles, Santa Barbara, Orange, San Bernardino and Riverside counties.
