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.

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 to not aggressively attack the fire right away.
