The nearly century-old Grand Canyon Lodge in far northern Arizona was a refuge for ambitious hikers and adventurous tourists eager to bask in the magnificent views of one of the most remote and renowned landscapes in the world.

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.

National wildfire policy has changed significantly over the past century. After the “Big Burn” of Idaho and Montana in 1910, federal fire officials treated all fires as an enemy and instituted a “10 a.m.” rule seeking to snuff them out within a morning of spotting them.

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.
