Evacuations were ordered Monday as the Stone Fire scorched land near Agua Dulce.
It’s unclear how many people are affected. Animal control officials are also being dispatched to the area to assist with evacuations of horses and other animals in the rural area.
The fire broke out early Monday afternoon and quickly scorched 1,000 acres of brush and threatened structures, according to county fire officials.
Dubbed the “Stone Fire,” the blaze was reported around 12:30 p.m. Monday near the 35100 block of Anthony Road and went to a third alarm by 1 p.m., according to the Los Angeles County Fire Department.

About 240 personnel were on scene, and a fixed-wing aircraft was deployed. The flames were burning in medium brush.
