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.

In this secluded paradise, mail still arrives by mule, turquoise cascades tumble into travertine pools, and time flows at the pace of the river.

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

The resulting Nankoweap landslide would have dumped enormous limestone boulders into the river corridor, creating a temporary dam and a lake whose surface may have reached 940 meters elevation before water overtopped and eroded the blockage, likely within 1,000 years.
