The Dragon Bravo Fire has destroyed dozens of structures and a water treatment facility on the Grand Canyon's North Rim.

GRAND CANYON NATIONAL PARK, Ariz. — 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.

The only lodging on the Grand Canyon’s North Rim was among dozens of structures consumed by the Dragon Bravo Fire, which has burned more than 5,000 acres.
