U.S. land managers have long known that they have a problem on their hands with overgrown forests and persistent drought. With the risk of catastrophic wildfire increasing, one tool is to use

A combination of high winds, dry air and above average temperatures caused a wildfire in the Grand Canyon to rapidly expand and cause major damage.

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.

As of Monday, the Dragon Bravo fire on the North Rim had consumed more than 5,700 acres and was not contained, according to the U.S. Forest Service.

Wildfires burning at or near the Grand Canyon's North Rim are still raging as strong winds, high heat and low humidity persist.
