A wildfire that destroyed a historic Grand Canyon lodge is continuing to spread out of control after it had been allowed to burn for days.

As crews battled to contain two wildfires in northern Arizona, Grand Canyon National Park implemented Stage 2 fire restrictions on Thursday.

The latest on the Dragon Bravo and White Sage fires. Plus, the trails, lodges, and campgrounds that are closed to visitors.

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.

The fire on the North Rim of the Grand Canyon started from a lightning strike but was managed as a controlled burn until it spread.

PHOENIX — Residents on the North Rim of the Grand Canyon have been ordered to evacuate due to a fire in Grand Canyon National Park. The fire, named the Dragon Bravo Fire, is approximately 5,716 acres and has 0% containment. It was caused by lightning on July 4, officials with the National Park Service said.

The fast-moving fire destroyed a historic lodge and dozens of other structures in the Grand Canyon National Park.

Wildfires can burn and spread differently depending on what vegetation they burn. The two fires in northern Arizona have varied landscapes. Ponderosa pine trees grow near the North Rim of the Grand Canyon and can live for hundreds of years.
