Arizona Gov. Katie Hobbs toured the Grand Canyon's North Rim on July 19 after the Dragon Bravo Fire left a path of charred mountainsides and burned-down structures.

Republic photographer Michael Chow captured the wildfire in a time-lapse video taken July 14 from the Canyon's South Rim. Chow set up his camera on a tripod, pointed it at the smoke, hoping it cleared at some point and and shot a photo every four seconds for 4 1/2 hours.

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.

A wildfire burning in Grand Canyon National Park triggered a chlorine gas leak Friday afternoon after flames reached a water treatment facility.
