GRAND CANYON NATIONAL PARK, Ariz. — A wildfire that tore through a historic Grand Canyon lodge and raged out of control Monday had been allowed to burn for days before erupting over the weekend, raising scrutiny over the National Park Service’s decision not to aggressively attack the fire right away.

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.
