The fire was ignited by lightning strikes on Thursday, prompting officials to evacuate the North Rim of the Grand Canyon National Park, according to the National Park Service.

On Friday, officials said in a post on X that roughly 500 visitors were evacuated from the area, and that park employees and residents remain sheltering in place.

The wildfire also prompted officials to evacuate the North Rim and South Rim of the Black Canyon of the Gunnison National Park, which remains closed to the public.

As the White Sage Fire rages on, the nearby Dragon Bravo Fire has grown to 1,500 acres on the North Rim of Grand Canyon National Park, officials said in a post on X on Friday.

"High temperatures, very low humidity, gusty winds, and very dry vegetation across the region” created a risk for wildfires to occur, officials said.

The National Park Service said in a statement on Friday that hiking in the Grand Canyon was not advised as the fires rage on and affect the park's air quality.
