The blaze burned downhill toward Monrovia and north toward State Route 2 in the Buckhorn Area, with “significant” western growth toward Mt. Wilson, Angeles National Forest officials reported.
Nearly 900 firefighters were working to stop the blaze, aided by five helicopters and four fixed-wing aircraft. Additionally, firefighters were setting strategic fires to help clear vegetation on the southern end of the blaze in the Santa Anita Canyon area near Chantry Flat, officials said.
The abnormally dry vegetation has been fueling the blaze, leading to extreme fire behavior and rapid rates of spread.
