Firefighters in a mountainous area north of Los Angeles are making good progress in their battle against a brush fire that forced thousands of people to evacuate.

A day after the Canyon Fire ignited in Ventura County, California, it has torched nearly 5,000 acres of land and triggered evacuation orders.

The fire is burning just south of Lake Piru, a reservoir located in the Los Padres National Forest. It’s close by Lake Castaic, a popular recreation area burned by the Hughes Fire in January. That fire burned about 15 square miles in six hours and put 50,000 people under evacuation orders or warnings.
