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 was among "numerous" historic structures to burn as two wildfires in northern Arizona triggered evacuations amid hot, dry and gusty conditions, officials said Sunday.

Parts of Grand Canyon National Park remained closed to the public Sunday because of wildfires and the release of chlorine gas from a North Rim water-treatment facility, the National Park Service said.
