Firefighters were battling two wildfires in southern California on Sunday that have forced nearly 2,000 people to evacuate.
The larger blaze burned 15,433 acres (6245 hectares), about 24 square miles (62 square kilometres), of dense, dry bush in the San Bernardino National Forest and was 12 per cent contained.
Authorities initially said the fire charred 18,000 acres (7,285 hectares), but infrared mapping overnight showed the fire was smaller.
About 340 residents were under mandatory orders to leave the Fawnskin area and another 1,200 voluntarily left their homes in the resort community of Green Valley Lake, a Forest Service spokeswoman said.
However, cooler temperatures were expected to aid firefighters and the fire was heading northwest away from the homes.
California Governor Arnold Schwarzenegger declared a state of emergency for San Bernardino County on Saturday, clearing the way for state government assistance with costs related to the fire.
The fire, which remained under investigation, burned several outbuildings at a campground.
About 1,080 firefighters were aided by 12 fixed-wing aircraft, 27 hand crews and 15 bulldozers.
