The Yarnell Fire burned in hilly terrain adjacent to the town of Yarnell, AZ (located south of Prescott, AZ). This event, caused by an lightning strike, lasted from June 28 - July 10, 2013 and burned over eight thousand acres of mountaineous terrain. Due to the high impacts caused by the fire, the event eventually gained a lot of attention by the local and national media and governments.

The location of the Yarnell Fire experienced less than average total precipitation during the 2012-2013 water year. The lack of precipitation, along with seasonally dry conditions in June, led to extremely dry vegetation. As a result, combustion easily began after the lightning struck a patch of vegetation. The rapid growth conditions were likely aided by strong and erratic winds created by thunderstorm outflow.
