A wildfire that leveled a historic lodge and visitors center on the Grand Canyon’s North Rim grew rapidly more than a week after it began as firefighters pushed ahead Monday with efforts to slow its spread.

The visitor center and a wastewater treatment plant were among the 50 to 80 structures lost, the park superintendent said. The area was evacuated Thursday.

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.
