Firefighters in Arizona were trying to contain a pair of fast-moving wildfires that destroyed a historic lodge in Grand Canyon National Park, closed a section of the park for the rest of the season and prompted calls for an investigation into federal authorities' wildfire response.

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 Grand Canyon Lodge was the park's one and only hotel, according the National Park Service, with the next nearest lodgings roughly 18 miles away.
