California's largest wildfire so far this year and the seventh-largest in state history spread overnight, while control of the Park Fire that has scorched two counties remained unchanged.
The containment rate remains at 12%.
The fire continues to burn hottest on the east side of Butte County's Butte Meadows area. Crews spent much of Sunday battling two fires in the area, each about 100 acres in size. Firefighters did a good job using bulldozers and pulling ropes around two fires overnight, officials said Monday.
Fire activity is also increasing on the west side of the fire east of the town of Darryville in Tehama County.
