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 inner canyon, including Phantom Ranch, was closed, as were trails to the inner canyon, because a water treatment facility on the North Rim was damaged by fire and was leaking chlorine gas, park officials said. Chlorine gas is toxic and is heavier than air, meaning it could settle into the lower part of the canyon.

A raging wildfire near the Grand Canyon in the US has destroyed dozens of buildings - including a historic lodge that was the only accommodation available within the surrounding national park's North Rim. The fire that destroyed the Grand Canyon Lodge is one of two that has swept across tens of thousands of acres in the area.
