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.

The Dragon Bravo Fire has destroyed dozens of structures and a water treatment facility, and the White Sage Fire, located in Kaibab National Forest, has forced hundreds to evacuate.

The Grand Canyon Lodge is the only hotel on the park's North Rim, which is closed for the rest of the season due to wildfire risk. The hotel was already rebuilt once, after a kitchen fire in 1932.
