According to Angeles National Forest officials, the blaze began shortly before 4 a.m. near the intersection of San Dimas Canyon and Golden Hills roads. Officials initially estimated the fire zone to be about 100 acres but later revised that number down as containment reached 20%.
No homes were immediately damaged or threatened, officials said. Flames seen in the area north of the 210 Freeway were moving away from residences as Los Angeles County Fire Department helicopters and fixed-wing aircraft performed water drops. County sheriff's deputies and La Verne firefighters and police officers were also at the scene.
