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

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

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.

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.
