The Dragon Bravo Fire in Arizona has destroyed dozens of structures and a water treatment facility on the Grand Canyon's North Rim.

Fire crews allowed a fire to burn through brush on the Grand Canyon’s North Rim. They they lost control.

The Grand Canyon Lodge in far northern Arizona that was an elusive getaway for nearly a century has been destroyed by a wildfire.

What fueled the explosive growth of the Dragon Bravo Fire was a mix of gusty winds, dry air and above-normal heat – weather conditions experts described as atypical for this time of year, when monsoonal moisture typically tamps down wildfire risk across Arizona.

A water treatment facility at the North Rim had been compromised by the fire, causing chlorine gas to fall towards the bottom of the canyon.
