YORBA LINDA, Calif. (AP) -- Firefighters tried to contain flames burning across more than 1,200 acres Tuesday in scattered fires from San Diego County to Palmdale.
An Orange County blaze spread over 900 acres of grassland near Chino Hills State Park, said Capt. Steve Miller of the county Fire Authority. The fire was reported shortly after 2 p.m. and the cause was unknown.
The blaze was moving away from homes in Yorba Linda and was 25 percent contained late Tuesday night, Miller said. Firefighters expected to have the fire fully contained by Thursday.
Three boys were seen running from the scene, and investigators hoped to locate them, Miller said.
Firefighters from Anaheim, Chino Hills Brea and the California Department of Forestry were helping county crews tackle the blaze.
No injuries were reported and no homes were threatened, Miller said.
In the San Bernardino National Forest, a 100-acre fire burning in stands of trees forced the evacuation of 1,200 children from campgrounds, officials said.
The fire was reported at 3:18 p.m. in the Barton Flats campground area, said Kim Boss, a spokeswoman for the U.S. Forest Service. More than 300 firefighters had 5 percent of the blaze contained by late Tuesday night.
Parts of Highway 38 were closed and an evacuation center was set up at Yucaipa High School, Bailey said.
There were no injuries reported and the cause was under investigation.
In Los Angeles County, a brush fire reported at 8:31 p.m. quickly burned 200 acres in the Palmdale area, said Kyle Sanford, a fire dispatcher. No homes were threatened and the cause of the fire was under investigation.
In San Diego County, a fire broke out at 2 p.m. in the northern part of the county in the Palomar Mountain area and burned 70 acres, said Matt Streck, a spokesman for the California Department of Forestry.
The fire was 80 percent contained late Tuesday night and full containment was expected early Wednesday morning, Streck said.
Firefighters were able to keep the blaze from spreading into Palomar Mountain State Park, which has a large amount of deed trees killed by bark beetle infestation, Streck said.
