The fire, which started Sunday in the East Fork of San Gabriel Canyon, had scorched about 4,000 acres and it was estimated 5 percent contained as of 4 p.m. Monday, Angeles National Forest spokesman John Wagner said.
There were about 500 personnel assigned to fire, which was burning in medium to heavy brush, all chaparral, on steep terrain, Wagner said. A half-dozen helicopters were also assigned to the fire, according to the Forest Service.

The fire was said to be pushing north toward the Sheep Mountain Wilderness area.
