The Dragon Bravo Fire started on July 4 and was managed at first as a controlled burn. Then the wind picked up, and it quickly became uncontrollable.

Gov. Hobbs is calling for an independent investigation into the fire's management, specifically questioning the decision to use a controlled burn during the hottest part of summer.

Parts of the Jacob Lake area are under GO evacuation orders, and the North Rim of the Grand Canyon is also evacuating. The fire has grown to more than 40,000 acres.
