Through the combined efforts of ground crews, engines, and aerial firefighting resources, officials confirmed that the fire reached 100% containment the following day.
The fire burned in an area near Deer Valley Road and Deer Hill Lane in southern Antioch, affecting open grasslands and rolling hills in eastern Contra Costa County.
