Photos: Firefighters Face Off With Canyon Fire In Northern LA County As Thousands Evacuate

PIRU, CA — The Canyon Fire held steady at nearly 5,000 acres overnight and firefighters are continuing to battle the blaze on the Los Angeles-Ventura county line, which stands at 25% containment.

The fire broke out in a remote, mountainous area near Lake Piru, west of the 5 Freeway and Santa Clarita, at around 1:30 p.m. Thursday. What started as a 30-acre brush fire exploded to 4,856 acres within eight hours.

The blaze prompted evacuation orders in more populated areas, including the Castaic area in Los Angeles County.

Some earlier evacuation orders have been downgraded to warnings.

"Air attack and ground crews aggressively attacked the fire to limit its spread and protect residents and structures in the fire's path," fire authorities from the two counties said in a statement.

One structure has been destroyed, but no homes have burned and no injuries have been reported.

"The hard work and operational efficiency mitigated residential structures from widespread damage, even as the high heat and dry conditions pushed the fire's growth," authorities said.

There are 391 firefighters working the blaze, using seven helicopters, 45 engines and three dozers, according to Cal Fire.

Additionally, several air takers are flying throughout the state, which is contenting with a number of active wildfires.

Los Angeles County Supervisor Kathryn Barger, who represents the area, issued a local emergency proclamation Thursday afternoon in response to the fire aimed at ensuring all resources are made available to fight the blaze.

She urged residents in the area to heed evacuation orders.

"The Eaton Fire showed us how quickly devastation can strike," she said. "It is never worth risking your life, the lives of your loved ones and pets, or the safety of those working to protect you. Your safety is my top priority, and swift action saves lives."

She also said refusing to evacuate complicates the work of firefighters, who must then concentrate efforts on preserving lives instead of property.
