Firefighters in Arizona were trying to contain a pair of fast-moving wildfires that destroyed a historic lodge in Grand Canyon National Park, closed a section of the park for the rest of the season and prompted calls for an investigation into federal authorities' wildfire response.

The fire was at 0% containment as of July 13.

Arizona Governor Katie Hobbs demanded an independent investigation into the federal government's handling of the fire, which was sparked by lightning on July 4.
