Los Angeles Fire Department spokesman Ron Myers said firefighters relied heavily on water-dropping units because of the rough terrain. “It’s a steep (area) with heavy brush,” Myers said. Officials reiterated concerns about the severe fire danger, with Los Angeles on track to have the driest rainy season on record.

UNIVERSAL CITY – Two Illinois teens surrendered Friday after allegedly touching off a wildfire that scorched the tinder-dry hills west of Griffith Park and spewed a column of smoke that could be seen for miles. About 300 firefighters and seven water-dropping air units battled the blaze, which spread quickly from five to 150 acres near Barham Boulevard and Forest Lawn Drive, officials said. At an evening news conference, Mayor Antonio Villaraigosa said the blaze had been deliberately set. “They’ve admitted that they started this fire,” Villaraigosa said of the 16- and 17-year-old boys, who turned themselves in to Burbank police and were later taken to the LAPD’s Hollywood station. No other details about the boys were available. Firefighters responded about 1 p.m. to a call at the Oakwood Toluca Hills Apartment Complex in the 3600 block of North Barham Boulevard. The fire was dangerously close to the facility, known for housing out-of-town actors looking for their big break in Hollywood. “It’s something you don’t want to see in your backyard, that’s for sure,” said actor and apartment resident Travis Caldwell, 18. “It was nuts. It started so small and it just raced right up the hill.” There were some anxious moments as flames threatened Warner Bros. Studios and the landmark Hollywood sign, but no structural damage was reported. One firefighter suffered a minor injury, officials said.
