Wildfires burning at or near the Grand Canyon's North Rim are still raging as strong winds, high heat and low humidity persist.

The White Sage Fire, burning in northern Arizona near the destructive Dragon Bravo Fire, continues to grow with evacuations still in place.

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.
