The fire on the North Rim of the Grand Canyon started from a lightning strike but was managed as a controlled burn until it spread.
The Dragon Bravo Fire has destroyed dozens of structures and a water treatment facility, and the White Sage Fire, located in Kaibab National Forest, has forced hundreds to evacuate.
What fueled the explosive growth of the Dragon Bravo Fire was a mix of gusty winds, dry air and above-normal heat β weather conditions experts described as atypical for this time of year, when monsoonal moisture typically tamps down wildfire risk across Arizona.
