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.

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 (NPS) confirmed.

A wildfire on the Grand Canyon’s North Rim has consumed some 5,000 acres and destroyed between 50 and 80 structures, including National Park Service administrative buildings, visitor facilities, a gas station and a water treatment plant.
