The blaze was discovered just before 4 p.m. Sunday afternoon, in the foothills on the northern side of Simi Valley near Cottonwood Drive.
No homes were damaged, and no evacuations were ordered. But, the blaze put up a huge plume of smoke. Because of the rugged terrain in the area, aircraft played a key role in efforts to contain the blaze.
Firefighters were able to get the upper hand on the fire in about two hours. The cause of the blaze is still under investigation.
