COCONINO COUNTY, Ariz. — Stage 2 fire restrictions will go into effect July 17 for Grand Canyon National Park due to the high threat of wildfire danger in the region. The U.S. Department of Interior said the restrictions will be applied to the South Rim and all other areas of the park.

As crews battled to contain two wildfires in northern Arizona, Grand Canyon National Park implemented Stage 2 fire restrictions on Thursday.

The fire on the North Rim of the Grand Canyon started from a lightning strike but was managed as a controlled burn until it spread.

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

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 new report has calculated that making national parks the responsibility of states would raise costs, cut revenue and reduce access for Arizonans.

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.

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.
