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 North Rim of the Grand Canyon has forced the closure of several trails and campgrounds. Meanwhile, life goes on at the South Rim where tourists endured a smokey visit Monday.

The Dragon Bravo Fire on the North Rim of Grand Canyon National Park is exhibiting “extreme and volatile fire behavior,” park officials said in a release Sunday.

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.

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.
