Nearly 400 firefighters are working around the clock on the Dragon Bravo Fire burning on the North Rim of Grand Canyon National Park, Tuesday.

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

A wildfire destroyed a historic lodge at the Grand Canyon's North Rim and some political leaders want to know if the fire was mismanaged. One fire expert said officials should approach policy changes carefully because controlled burns are still critical to forest health.

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.

Crews fighting a wildfire were focused on stopping the flames from consuming nearby cabins, a water pumping station, mule stables and other structures, fire officials said.
