Arizona Department of Public Safety Officers and Yavapai County Sheriff Officers salute the fire vehicles used by the 19 firefighters who perished battling a fast-moving wildfire in Peeples Valley, Arizona July 3, 2013. Weary crews on Tuesday looked for a break in the weather to gain ground against a fierce Arizona wildfire that has already killed 19 of their fellow firefighters in the worst wildland fire tragedy in 80 years. Fire managers say the so-called Yarnell Hill fire, which has already charred nearly 8,400 acres (3,400 hectares) of tinder-dry chaparral and grasslands northwest of Phoenix, was zero percent contained as darkness fell on Monday evening.
