The Dragon Bravo Fire destroyed the historic Grand Canyon Lodge and continues to burn in northern Arizona. See photos of the devastation.

A wildfire that tore through a historic Grand Canyon Lodge​ had been allowed to burn for days before erupting over the weekend, raising questions about federal officials' decision not to aggressively attack it right away.

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 and Senators Mark Kelly and Ruben Gallego are calling for an independent investigation into how federal officials managed the Dragon Bravo Fire burning on the North Rim of Grand Canyon National Park.

A Grand Canyon water treatment facility located at the North Rim caught fire on Saturday, causing chlorine gas to be released into the air. Multiple closures are being enforced due to the incident.
