Wildfires burning at or near the Grand Canyon's North Rim are still raging as strong winds, high heat and low humidity persist.

A wildfire destroyed a historic lodge at the Grand Canyon's North Rim and some political leaders want to know if the fire was mismanaged. One fire expert said officials should approach policy changes carefully because controlled burns are still critical to forest health.

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 water treatment facility at the North Rim had been compromised by the fire, causing chlorine gas to fall towards the bottom of the canyon.
