Abnormally dry, hot conditions near the Grand Canyon's North Rim allowed the Dragon Bravo Fire to grow rapidly.

Here's what's open and closed at Grand Canyon North Rim, South Rim and Phantom Ranch in the wake of wildfires that destroyed the North Rim lodge.

If you’re looking to avoid the crowds, you might want to consider visiting one of the thousands of state parks across the country.

A mix of high temperatures, gusty winds, low humidity, and dry vegetation has fuelled the fire's swift advance in Arizona, officials say.

Two separate cases of zoonotic diseases, hantavirus and rabies, were confirmed at Grand Canyon National Park. A park employee tested positive for hantavirus, while a bat found near the Colorado River tested positive for rabies.

Wildfires can burn and spread differently depending on what vegetation they burn. The two fires in northern Arizona have varied landscapes. Ponderosa pine trees grow near the North Rim of the Grand Canyon and can live for hundreds of years.

The NWS warning was in effect for regions of the Grand Canyon below 4,000 feet elevation. Temperatures were forecast to potentially reach 110 degrees at Phantom Ranch and 102 at Havasupai Gardens.

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.
