The building was surrounded by vegetation on fire when a team of “helitack” firefighters arrived to protect the area on Tuesday. Grand Canyon National Park officials said the crews knew if the pump house fell, the consequences could cripple park operations for months.

The Dragon Bravo Fire in Arizona has destroyed dozens of structures and a water treatment facility on the Grand Canyon's North Rim.

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.

The Dragon Bravo Fire started on July 4 and was managed at first as a controlled burn. Then the wind picked up, and it quickly became uncontrollable.

As of Monday, the Dragon Bravo fire on the North Rim had consumed more than 5,700 acres and was not contained, according to the U.S. Forest Service.

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.
