Crews with hand tools battled to contain wind-whipped Arizona wildfires on Wednesday that have raced across more than 30 square miles of parched ponderosa forest, brush and grassland, consuming several buildings and threatening a small town. The Sunflower Fire, the largest of at least four blazes in central and eastern Arizona, has burned nearly 20 square miles (52 square kilometers) in the Tonto National Forest, about 40 miles north of Phoenix, fire officials said.
