A wildfire in tinder-dry forest on the North Rim of the Grand Canyon grew around 50% on Tuesday after it destroyed dozens of buildings, prompting public outrage that it was left to burn for a week before firefighters tried to fully extinguish it.

The Dragon Bravo Fire has burned more than 8,500 acres southeast of the Grand Canyon. The fire was sparked by lightning on July 4 and has destroyed dozens of structures on the North Rim, including the historic Grand Canyon Lodge.

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.

Arizona Governor Katie Hobbs has called for an independent investigation into the federal response management of a wildfire that caused numerous residents and workers to evacuate and destroyed a historic 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.

Fire activity on the Dragon Bravo Fire, located at Grand Canyon National Park’s North Rim, remains “extremely active,” according to an incident update Monday.

The Dragon Bravo Fire started on July 4 and was managed at first as a controlled burn. Then the wind picked up, and it quickly became uncontrollable.

Dozens of buildings inside the North Rim of the Grand Canyon have been destroyed, including a historic lodge, as a chlorine gas leak has forced firefighter evacuations from the Dragon Bravo Fire.
