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.

Firefighters are battling a lightning-caused wildfire on the North Rim of the Grand Canyon. The Dragon Bravo Fire has burned down the Grand Canyon Lodge and triggered a chlorine gas leak.

The visitor center and a wastewater treatment plant were among the 50 to 80 structures lost, the park superintendent said. The area was evacuated Thursday.
