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