A helicopter drops water on the Copco Fire, which burned some 144 acres in the Grapevine, 3 miles east of Gorman.
A brush fire that scorched 144 acres of brush in a hilly, remote area of the Angeles National Forest near Gorman was nearly fully contained on Sunday.
Firefighters mopped up hot spots as patrols on the ground and in the air surveyed the landscape to make sure there were no flames, said Carol Lew, a spokeswoman with the Angeles National Forest.
Fire investigators, meanwhile, continued to probe the cause of the fire.
The so-called Copco Fire started on Saturday before noon near an aqueduct called Quail Lake, off Lancaster Road, which is about 3 miles east of Gorman.
One firefighter suffered minor burns, but there were no other injuries reported.
At its height Saturday more than 300 firefighters, assisted by several water-dropping helicopters, battled the flames.
Officials were concerned about the proximity of the fire to overhead power lines and a gas pipeline in the area. But no homes or businesses were threatened and no evacuations were ordered, fire officials said.
Though the fire was visible from the 5 Freeway, it did not affect traffic, officials said.
