The Jerusalem fire burned 25,118 acres in Napa and Lake counties, eventually joining the southern flank of the Rocky Fire, which was extinguished Aug. 14.
Members of the public are cautioned to be aware of their surroundings when outdoors and are asked to report any smoke, which may indicate spot fires.
Visitors are also reminded that campfires are not allowed on the wildlife area.
