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.

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.
