The Grand Canyon's North Bravo Fire intensified on July 11, the day before Katy Rock Shop owner Jacob Proctor and his family arrived at the national park.

Fire activity on the Dragon Bravo Fire, located at Grand Canyon National Park’s North Rim, remains “extremely active,” according to an incident update Monday.

The Grand Canyon Lodge was one of dozens of structures destroyed in a fast-moving wildfire in Arizona over the weekend, the National Park Service confirmed.

Grand Canyon National Park evacuated Phantom Ranch and areas of the inner canyon after the rapidly growing Dragon Bravo Fire led to the leak of poisonous gas.

A Grand Canyon water treatment facility located at the North Rim caught fire on Saturday, causing chlorine gas to be released into the air. Multiple closures are being enforced due to the incident.
