A major brush fire continued to burn Sunday morning in a remote area near Castaic Lake.
The fire broke out Saturday and spread from 5 acres to 500 acres in little more than two hours. By Sunday morning, fire crews were holding it at about 1,000 acres with 10 percent containment.
No homes were threatened, though two outbuildings had been destroyed.
Visitors to the area have been evacuated. The upper east launch ramp of the lake was closed, but the western launch ramp remained open.
Firefighters made progress Saturday on the west side of the fire. On Sunday they were turning their focus on the eastern front.
"We actually had to get firefighters in boats to get them across the lake to fight this fire. The other areas are higher up in the Angeles National Forest so we can get to them through fire roads and other means," said Nathan Judy, a spokesman for the Angeles National Forest.
Crews faced another day of scorching heat, too, with temperatures expected to break 100 degrees in the area.
A cause has not been determined, but Judy told KPCC this was a good time to remind folks headed to the forest for Father's Day to be careful.
"If you are going to have a charcoal barbecue or a camp fire, they're only allowed within our campgrounds that are designated for that use with what we provide, the metal ring, or the stand up barbecue. Anything else is not legal in the Angeles National Forest," he said.
