The Dragon Bravo Fire has destroyed dozens of structures and a water treatment facility, and the White Sage Fire, located in Kaibab National Forest, has forced hundreds to evacuate.

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.

The White Sage and Dragon Bravo wildfires in Arizona have together burnt more than 40,000 acres and destroyed the historic Grand Canyon Lodge. Up to 80 other structures in the Grand Canyon National Park's North Rim, including a water treatment facility, have also been lost. No injuries are reported.
