Headline: Dragon Bravo Fire Remains Largest Wildfire in U.S. as Containment Reaches 12%
The Dragon Bravo Fire, currently the largest wildfire in the nation, continues to rage in northern Arizona. The fire, which started on July 4, 2025, near the Grand Canyon North Rim, has scorched nearly 116,592 acres as of August 3, 2025[1].
The fire, which was sparked by lightning, has led to several closures, including the North Rim of Grand Canyon National Park being closed for the entire 2025 season[4][5], and State Route 67 south of Jacob Lake is closed[3]. Over 70 structures, including a historic lodge on the Grand Canyon's North Rim, have been destroyed[2].
The fire involves mixed fuels such as mixed conifer, aspen regeneration, ponderosa pine, pinon-juniper, and sage[1]. Over 1,200 personnel are involved in firefighting efforts[1].
Despite the efforts of over 1,100 fire personnel, the fire remains only 12% contained[1]. Fire officials are continuing to deal with extreme fire behavior due to the alignment of slope, fuel, and wind[1].
The weather forecast for the region is expected to be hot, dry, and breezy for the rest of the week, which could exacerbate the situation. U.S. Highway 89A, north and east of the Kaibab National Forest and south of the main stem of Soap Creek and north and west of Grand Canyon National Park, is temporarily closed[3].
A public meeting regarding the fire was scheduled for August 5, 2025, in Fredonia, Arizona, to update the community and provide further information from incident management[1]. For updated information, the public can contact the Southwest Area Complex Incident Management Team 2 at 928-268-5610 or by email at [email protected][1][2].
