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.

A raging wildfire near the Grand Canyon in the US has destroyed dozens of buildings - including a historic lodge that was the only accommodation available within the surrounding national park's North Rim. The fire that destroyed the Grand Canyon Lodge is one of two that has swept across tens of thousands of acres in the area.
