In Arizona, state officials are demanding an investigation as parts of Grand Canyon National Park have been evacuated and a historic lodge has been destroyed by an out of control, 5,000-acre fire.

The wind-driven Dragon Bravo Fire jumped containment lines on the Park’s North Rim over the weekend. On Saturday night, it grew 500 acres, destroying more than 50 structures, including the 1930s-era Grand Canyon Lodge. Park officials say the fire also burned the water treatment facility, releasing poisonous chlorine gas and forcing firefighters to pull back.

The North Rim is closed for the season while the popular South Rim remains open.

Arizona Gov. Katie Hobbs called for an independent investigation into the fire on Sunday. She says Arizonans deserve to know why the federal government chose to manage the fire as a controlled burn during the hottest part of Arizona’s summer.
