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.

A wildfire that leveled a historic lodge and visitors center on the Grand Canyon’s North Rim grew rapidly more than a week after it began as firefighters pushed ahead Monday with efforts to slow its spread.

Two fast-moving wildfires—the Dragon Bravo and White Sage fires—have scorched more than 45,000 acres, destroyed the iconic North Rim lodge and dozens of structures, and led to long-term closures in the Grand Canyon.
