The Dragon Bravo Wildfire burning inside Grand Canyon National Park has destroyed dozens of structures, including a beloved and historic lodge.

The Grand Canyon Lodge was one of dozens of structures destroyed in a fast-moving wildfire in Arizona over the weekend, the National Park Service (NPS) confirmed.

Parts of Grand Canyon National Park remained closed to the public Sunday because of wildfires and the release of chlorine gas from a North Rim water-treatment facility, the National Park Service said.
