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 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.

As of Monday, the Dragon Bravo fire on the North Rim had consumed more than 5,700 acres and was not contained, according to the U.S. Forest Service.
