GRAND CANYON NATIONAL PARK, Ariz. — A wildfire that tore through a historic Grand Canyon lodge and raged out of control Monday had been allowed to burn for days before erupting over the weekend, raising scrutiny over the National Park Service’s decision not to aggressively attack the fire right away.

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.

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.
