PALM SPRINGS, Calif. (AP) -- Two wildfires that prompted evacuation of dozens of homes remained out of control Tuesday after burning more than 8,400 acres of Southern California brush and forest.
No homes were destroyed, authorities said.
The cause of both fires remained under investigation.
Three firefighters suffered heat exhaustion Monday as they battled a 5,000-acre blaze on the edge of the San Bernardino National Forest west of Palm Springs. Two campgrounds were evacuated as about 1,000 firefighters, backed by helicopters and planes, worked to contain the fire that began Sunday afternoon.
The blaze was 25 percent contained, but could still threaten the mountain communities of Idyllwild, Pine Cove and Garner Valley, officials said.
Temperatures in the Riverside County area were expected to exceed 100 degrees.
In northern Los Angeles County, a 3,200-acre fire in the Lake Hughes area of the Angeles National Forest was 30 percent contained.
The fire prompted the mandatory evacuation of 10 homes in the Happy Valley community shortly after midnight, county fire Inspector John Mancha said. About 24 homes in nearby communities were evacuated voluntarily Monday.
More than 500 county firefighters and hundreds of others from other agencies were on the line, Mancha said.
The blaze started about 12:30 p.m. Monday and quickly spread in the heavy brush, fanned by winds that gusted around 20 mph, Mancha said.
The fire moved into thick forest that hadn't burned in 75 years, county Fire Department spokesman Mike McCormick said.
In Los Angeles, 90 Boy Scouts were evacuated from a camp in Griffith Park after a blaze erupted Monday afternoon. It burned only four acres before it was contained in a little over an hour.
