The Grand Canyon's North Bravo Fire intensified on July 11, the day before Katy Rock Shop owner Jacob Proctor and his family arrived at the national park.

Gov. Katie Hobbs wants an independent federal investigation on the handling of the Dragon Bravo wildfire, which has burned more than 5,700 acres as of Monday.

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.

Wildfires can burn and spread differently depending on what vegetation they burn. The two fires in northern Arizona have varied landscapes. Ponderosa pine trees grow near the North Rim of the Grand Canyon and can live for hundreds of years.
