Progress in fighting 4 Arizona wildfires PHOENIX, May 20 (UPI) -- Diminishing winds helped hundreds of firefighters battling four wildfires in Arizona make headway to shrink them, officials said. The largest of the four, known as the Sunflower fire, has been burning since May 12 northeast of Phoenix. It has consumed 16,600 acres and is considered 33 percent contained, The Arizona Republic said. The second largest fire named Gladiator was started by a house fire a week ago and has about 13,000 acres burning, officials said. It's considered 10 percent contained and evacuation orders remained for about 350 people in towns northeast of Phoenix. The Bullflat fire on the Fort Apache Indian reservation was started by a lightning strike May 10 and has destroyed 2,145 acres since. Firefighters say it is 80 percent contained. The easternmost Elwood fire on the remote San Carlos Indian reservation was considered 60 percent contained after consuming nearly 1,600 acres, firefighters said. The cause of the Elwood fire is under investigation, the report said.
