The Dragon Bravo Fire in Arizona has destroyed dozens of structures and a water treatment facility on the Grand Canyon's North Rim.
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.
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.
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.
Grand Canyon officials were forced to close the North Rim for the remainder of the season after flames destroyed an iconic lodge and dozens of other structures.
