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 Dragon Bravo and White Sage wildfires burned throughout the North Rim. According to local officials, the Dragon Bravo Fire “exhibited extreme and volatile fire behavior” over the weekend, and it expanded to around 5,000 acres of land, per CBS News.
