The blaze has consumed 44 square miles of rugged, densely forested land about 30 miles east of Redding.
The fire, sparked by lightning Saturday, was 57 percent contained Thursday and continued to threaten 900 homes.
About 2,500 firefighters are working to contain the fire burning near small towns in Shasta and Tehama counties. The blaze was one of several major fires burning across California.
On Wednesday, Gov. Jerry Brown declared a state of emergency in Plumas, Shasta and Tehama counties in response to the wildfires.
