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.

Researchers have found a link between two geological events in iconic locations of the U.S. Southwest that scientists previously didn't think had anything to do with each other.

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 new study suggests ancient wood floated into a cave far above the Colorado River when a meteorite-induced earthquake triggered a landslide, a dam, and an ancient lake.

A wildfire in tinder-dry forest destroyed dozens of buildings, prompting public outrage that it was left to burn for a week before firefighters tried to fully extinguish it.

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.

Watt and Braman entered the league together in 2011, with Watt being the No. 11 overall pick in the draft that year. As of this writing, Braman's GoFundMe has raised over $88,000, which is well past the initial goal of $25,000.
