Arizona wildfire rages on

A vast wildfire, measuring half the size of the state of Rhode Island and described as the second worst fire in Arizona history, continues to surge across eastern Arizona. The fire has jumped past firefighter's containment lines to reach the edges of residential areas, prompting more evacuation orders. Winds carrying burning embers continue to ignite smaller fires, causing new concerns about the prospect of extinguishing the 13-day-old fire. The Wallow Fire has destroyed approximately 337,000 acres and threatens main electrical lines that supply power as far away as west Texas. Thousands have evacuated. Paula Nelson (35 photos total)
