The Dragon Bravo Fire burning on the North Rim of Grand Canyon National Park has grown to 105,415 acres, officially putting it in the range of a “megafire”. The wildfire began on July 4th, 2025, likely due to a lightning strike. Mixed conifer, aspen regeneration and ponderosa pine are the primary fuel source for the fire. 1,194 personnel are currently assigned to the fire.
When Does A Wildfire Become A “Megafire”?
According to National Geographic, the U.S. Interagency Fire Center defines a megafire based on its size. When a wildfire burns more than 40,500 hectares, or 100,000 acres, it falls into the definition of a megafire. Once rare, these massive wildfires have become more and more common over the past 40 years.
Grand Canyon Wildfire Operations
The Grand Canyon wildfire is currently approaching a transition of fuels in the north and east, which could wind up altering the progression of the fire. Crews are continuing to reinforce what they’ve already accomplished in the north on the 213 road.
Work along Forest Road 22 west of State Route 67 will continue in order to protect the area around Kaibab Lodge and the park entrance station. Crews are working to protect cultural values on the Walhalla Plateau as well. It is possible that the fire could burn itself out upon reaching the scar from the 2018 Obi Fire.
