A fire near the southern edge of Millville Plains was quickly contained by an aggressive Cal-Fire response Thursday afternoon. The blaze broke out at One O'clock off of Dersch Road near Golden Lane about a half mile east of Cow Creek. It burned about 7 acres of mostly grass land and was contained within an hour. Cal-Fire was assisted by firefighters from Millville and Palo Cedro. The cause has been determined to be a hot exhaust pipe on a vehicle that was driven into the tall dry grass.
