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

A wildfire that destroyed a historic Grand Canyon lodge is continuing to spread out of control after it had been allowed to burn for days.

A wildfire that tore through a historic Grand Canyon Lodge​ had been allowed to burn for days before erupting over the weekend, raising questions about federal officials' decision not to aggressively attack it right away.

The Dragon Bravo Fire burning inside Grand Canyon National Park has destroyed dozens of structures, including a beloved and historic lodge.

In this secluded paradise, mail still arrives by mule, turquoise cascades tumble into travertine pools, and time flows at the pace of the river.

The resulting Nankoweap landslide would have dumped enormous limestone boulders into the river corridor, creating a temporary dam and a lake whose surface may have reached 940 meters elevation before water overtopped and eroded the blockage, likely within 1,000 years.

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.
