Crews have worked through the night to build containment lines around a wildfire in rural Northern California that has burned more than 4 square miles, damaged five structures and prompted mandatory evacuations. State fire spokeswoman Stacie McCambridge says the blaze began shortly before noon Tuesday in the Pope Valley area of Napa County. It grew to 2,700 acres by late Tuesday. State firefighters and crews from Napa, Lake and Solano counties spent the day working in 90-degree weather as they contained 30 percent of the fire.
