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.

The National Park Service is pushing back against members of Congress who accused the agency of allowing the Dragon Bravo Fire to spin out of control on the Grand Canyon’s North Rim.

Gov. Katie Hobbs questioned why the U.S. government decided to manage the Dragon Bravo fire, which started with a lightning strike, as a “controlled burn” during the height of the summer.

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.

Arizona's governor has demanded an investigation into why a wildfire that destroyed a historic lodge and dozens of other structures on the North Rim of the Grand Canyon was allowed to burn for a week before federal firefighters tried to put it out.

As of Monday, the Dragon Bravo fire on the North Rim had consumed more than 5,700 acres and was not contained, according to the U.S. Forest Service.

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.

A mix of high temperatures, gusty winds, low humidity, and dry vegetation has fuelled the fire's swift advance in Arizona, officials say.
