Arizona's governor has demanded an investigation into why a wildfire that destroyed a historic lodge and dozens of other structures on the North Rim of the Grand Canyon was allowed to burn for a week before federal firefighters tried to put it out.

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.

A historic lodge and dozens of other structures on the Grand Canyon’s North Rim have been destroyed by a fast-moving wildfire, prompting officials to close access to the area.
