As of 11 p.m. Sunday, the fire burned more than 22,000 acres and was 20 percent contained, according to the U.S. Forest Service. Officials had earlier estimated that the fire was at 25,000 acres. Full containment is not expected until next Monday.
The blaze was burning near the Antelope Valley California Poppy Reserve. It jumped the California Aqueduct near West Lancaster Road and was threatening a farm.
Officials say in some areas, the brush hasn't burned since 1929. Tinder dry brush combined with low humidity, high heat and fierce winds created a massive firestorm that cost some residents everything.
"We had to evacuate. We left immediately. We didn't have time to pick up anything," Monique Hernandez said through tears.

Saturday evening, a hiker was spotted in the middle of the forest, right in the path of the fire. One of the attack aircraft dropped a fire shelter down to him. Officials said within about half an hour, firefighters were able to scoop him up and rescue him.
High temperatures, rugged terrain and shifting winds are creating obstacles for crews. Also, downed power lines are posing a hazard. Firefighters say they've noticed arcs of electricity jumping from the ground in their direction.
Local health officials warned that air quality in the Santa Clarita Valley and San Gabriel Valley mountains will be unhealthy for sensitive individuals throughout the weekend due to the fire, and they urged residents to take precautions and stay indoors if possible.
The cause of the fire remains under investigation.
