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.

Arizona’s governor is calling for a “comprehensive and independent” investigation after a wildfire in Grand Canyon National Park torched thousands of acres and destroyed dozens of structures, including the iconic Grand Canyon Lodge.
