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 engulfed the Grand Canyon Lodge on the North Rim, destroying the landmark building and dozens of structures while firefighters battle a second blaze north of the canyon.

A Grand Canyon water treatment facility located at the North Rim caught fire on Saturday, causing chlorine gas to be released into the air. Multiple closures are being enforced due to the incident.

Authorities maintained the evacuation zones for the White Sage Fire north of the Grand Canyon as the fire grew expectantly.
