One week ago, the Yarnell Hill Fire covered only a few hundred acres, burning in dense brush 85 miles northwest of Phoenix. Then last Sunday, it exploded. Powerful winds and dry fuel propelled the fire across thousands of acres in a matter of hours, engulfing 19 elite firefighters who were trying to keep it from reaching the nearby town of Yarnell.
Nearly 700 firefighters stepped in to battle the blaze after that. A week later, the fire is nearly contained.
