Grand Canyon Wildfire Spreads to More Than 126,000 Acres
The Dragon Bravo fire has been burning for more than a month, fueled by record-low humidity that has hampered containment efforts.
The mayor of Fredonia, Ariz., declared that his town of about 1,300 people just north of the park was facing a 'significant and ongoing wildfire emergency' because of the fire. Businesses were struggling with supply chain interruptions, ranchers have been displaced and the tourism economy, dependent on more than one million annual visitors, is expected to suffer, according to the emergency declaration, which was issued on Monday.
The declaration called for better forest management of the Kaibab National Forest, reviving a criticism of the response to the Grand Canyon wildfire after Gov. Katie Hobbs of Arizona called for an investigation last month into why the federal government had decided to manage it as a 'controlled burn.'
The local economies around Fredonia, Arizona's northernmost town, and the Kanab area in southern Utah across the state line rely on visitors to the national park and have been affected by the closures along the Grand Canyon's North Rim.

Grand Canyon ‘Megafire' Explodes in Size and Is Now Creating Its Own Weather
Despite over a month of firefighting efforts, the Dragon Bravo fire experienced a surge of growth this week, doubling in size within just a few days. The northern Arizona 'megafire' is now the largest active blaze in the continental U.S. and the largest of 2025 so far. As of Wednesday, August 6, the Dragon Bravo fire has torched 130,520 acres along the Grand Canyon's North Rim, according to the national wildfire monitoring database InciWeb. This fire sparked to life when lightning struck the area on July 4. National Park Service responders initially tried to manage the Dragon Bravo Fire with a confine-and-contain strategy, but it quickly grew out of control. This week, dry heat and gusty winds stoked another surge of rapid growth, challenging crews already struggling to control the blaze across rough terrain. According to a Wednesday InciWeb update, they have only managed to contain 13% of the fire. The fire was pushing north on Tuesday, August 5, and crews deployed ground and air resources to minimize the growth of this new front. This strategy should drive the inferno into territory where it will quickly run out of fuel, according to the InciWeb update, but high heat and low humidity will continue to stoke the flames through Friday. To make matters worse, the fire is burning so hot that it's generating weather that could help it spread more rapidly. On Thursday, July 31, fire information officer Lisa Jennings told the Associated Press that towering 'pyrocumulus' clouds had been hanging over the inferno for a week straight. These enormous, anvil-shaped convection clouds form when air over the fire becomes superheated and rises in a large smoke column. If there is sufficient water vapor in the atmosphere and the updraft intensifies, pyrocumulous clouds can develop into pyrocumulonimbus clouds, according to the Royal Meteorological Society. These clouds may produce intense localized rain, which would help to dampen the fire, or create downdrafts that spread embers far and wide. They can also generate dangerous fire tornadoes. The Dragon Bravo fire has already destroyed dozens of structures—including the historic Grand Canyon Lodge—triggered evacuations, and forced officials to close the North Rim for the remainder of the 2025 season, according to the National Park Service. There have been no reports of fatalities or damages. Dragon Bravo is currently one of four large, active wildfires in Arizona and one of 42 burning across the U.S., the National Interagency Fire Center reported Wednesday. With wildfire season in full swing, federal agencies that fight wildfires are navigating devastating staff cuts. Under the Trump administration, the Park Service has lost 24% of its permanent workforce, according to the National Parks Conservation Association. A recent ProPublica investigation found that over one-fourth of the Forest Service's firefighting jobs were vacant as of July 17. The agency has publicly maintained that it has sufficient staff and resources to handle what's already shaping up to be an active season, but in July, more than a dozen active and retired Forest Service employees told Reuters the agency was struggling to fill vacancies. Climate change is exacerbating the extreme weather conditions fueling the relentless Dragon Bravo fire, worsening wildfire activity on a global scale. This inferno underscores the risks of weakening U.S. firefighting capacity while failing to reduce planet-warming emissions. At this rate, severe, unmanageable fires like Dragon Bravo are quickly becoming the new norm.

How the Dragon Bravo Fire created its own weather
The massive wildfire burning near the Grand Canyon has been so intense at times that it created its own weather. The Dragon Bravo Fire -- which has scorched more than 130,000 acres in Arizona north of the Grand Canyon -- has become so hot that it spurred pyrocumulus clouds, or "fire clouds" at points. The fire-driven clouds can form when the heat and smoke from a very large wildfire is released into the atmosphere, according to the National Oceanic and Atmospheric Administration. Pyrocumulus clouds are similar to the cumulus clouds that can been seen on a fair-weather day; however, instead of rising due to heat from the sun-warmed ground, the air is lifted by intense heat from a fire, causing it to cool and condense water vapor, forming a new cloud. The formation of pyrocumulus clouds and a wildfire's ability to generate its own weather also depend on the broader weather pattern affecting the region. At times, these clouds can grow so large that they generate their own intense, erratic winds and even produce lightning. The most intense are called pyrocumulonimbus clouds, which are similar to a thunderstorm in structure and potential weather impacts. Even when pyrocumulus clouds don't form, the intense heat from a massive wildfire can still create locally strong, gusty winds in the area. The Dragon Bravo Fire broke out on July 4 as a result of a lightning strike and was driven by inaccessible terrain and winds, according to Grand Canyon National Park. Since then, it has grown to a " megafire," defined by the National Interagency Fire Center as a wildfire that burns more than 100,000 acres. It is about 13% contained, and more than 1,300 personnel are battling the blaze, according to Inciweb, an interagency risk incident information platform. Critical fire weather returned to the region on Sunday due to a drop in humidity, according to the National Interagency Fire Center. The mayor of Fredonia, Arizona, declared a local emergency on Monday due to the ongoing wildfire disaster. The fire destroyed the Grand Canyon Lodge, a National Historic Landmark and the only in-park lodging option in the North Rim of the Grand Canyon National Park, according to NPS. The lodge first opened in 1937. Dozens of structures have been destroyed by the fire, including the North Rim Visitor Center and several guest cabins, according to NPS. The local watershed has also been impacted. An "aggressive full suppression strategy" is being deployed to manage the fire, according to NPS. Crews will continue to hold and reinforce lines around the perimeter of the fire, the National Interagency Fire Center said. Arizona Gov. Katie Hobbs has called for a federal investigation into the management of the fire. The North Rim of the park closed for the 2025 season as a result of the damage and losses from the fire.
