Crews working through the night in steep terrain are building containment lines around a wildfire near the rural Northern California town of Weaverville that forced the evacuation of about 200 homes.
CalFire spokeswoman Cris Hartman said early Monday that the fire is 25 percent contained.
She said the flames did not spread overnight. The fire has burned a little more than 1 square mile, or 650 acres, of timber and brush about 2 miles west of the Gold Rush-era boomtown.
Hartman said the blaze, sparked Sunday afternoon near Highway 299, has damaged one structure, likely a barn or a large outbuilding.
Officials said daylight will bring increased risks as gusty winds and dry conditions return.
