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.

A combination of high winds, dry air and above average temperatures caused a wildfire in the Grand Canyon to rapidly expand and cause major damage.

A wildfire in tinder-dry forest destroyed dozens of buildings, prompting public outrage that it was left to burn for a week before firefighters tried to fully extinguish it.

Highway closures and evacuations remain in effect as a wildfire burns more than 58,000 acres in Coconino County. It is one of two blazes raging at or near the northern rim of the Grand Canyon.

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.
