All wood-burning and charcoal fires, such as campfires and charcoal barbecues, are prohibited. In addition, visitors and residents can only use liquid petroleum appliances like stoves, lanterns or heating devices in an empty area or one that doesn’t have flammable materials within three feet.

Here's what we know about the two wildfires that have destroyed tens of thousands of acres of forest and burned at least 70 structures.

The destruction caused by this fire is a reminder of how vulnerable our national parks and residents nearby are to the impacts of a changing climate. NPCA stands ready to support efforts to rebuild and restore what’s been lost and ensure the National Park Service has the resources it needs to protect the Grand Canyon experience for the millions of visitors who travel there each year.

The visitor center and a wastewater treatment plant were among the 50 to 80 structures lost, the park superintendent said. The area was evacuated Thursday.

Two Arizona wildfires wreaking havoc north of the Grand Canyon were still burning with no containment as of Monday morning.

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.
