Nearly 400 firefighters are working around the clock on the Dragon Bravo Fire burning on the North Rim of Grand Canyon National Park, Tuesday.
It took one week for a naturally occurring wildfire at Grand Canyon National Park to grow from a low-level threat to a full-on disaster. On July 4, a lightning strike ignited a wildfire on the North Rim of Grand Canyon National Park.
The Dragon Bravo Fire started on July 4 and was managed at first as a controlled burn. Then the wind picked up, and it quickly became uncontrollable.
