The Cottonwood Fire has reached 90% containment after burning an estimated 97,458 acres near Beaver, Utah, according to a July 18, 2026, update from InciWeb. As fire officials continue to monitor the blaze, which began on June 22, efforts are shifting toward evaluating existing evacuations and closures for potential reduction.
Incident Management and Reentry Efforts
The Great Basin Complex Incident Management Team (CIMT) #4 took command of the fire operations on July 8, 2026. Under the direction of Incident Commander Steve Shaw, the team has been working alongside the Beaver and Paiute County Sheriffs’ Offices to manage the impact of the massive wildfire.
According to official incident information, the management team is specifically focused on coordinating with local law enforcement to evaluate when conditions will be safe enough for residents and the public to begin reentry into previously evacuated areas. This process involves a careful assessment of fire activity and safety risks within the perimeter.
Fire Origin and Fuel Composition
The fire, which originated on June 22, 2026, at approximately 3:36 p.m., experienced rapid growth during its initial stages. InciWeb reports that the spread was fueled by extremely dry fuels and weather conditions that were highly conducive to fire movement.
The primary fuel types involved in the blaze consist of a high density of timber and shrub. Specifically, forest litter combined with a significant shrub component—including manzanita, mountain mahogany, and shrub oak—has driven much of the fire's progression through the landscape.
Weather Impacts and Suppression Tactics
Despite the massive scale of the fire, recent weather patterns have provided some relief to ground crews. InciWeb noted that while heavy rainfall impacted certain portions of the fire area, it did not affect all parts of the incident. Additionally, daytime humidity levels have helped limit the potential for further fire growth.
However, significant challenges remain for the 542 personnel currently assigned to the incident. Firefighters are continuing to construct direct containment lines along the fire perimeter to minimize further acreage burned. Crews must still contend with steep terrain, limited access to certain areas, and ongoing dry fuel conditions.
Current Status and Investigation
The cause of the Cottonwood Fire remains under investigation. The fire is located approximately five miles east of Beaver, Utah, and continues to be a major focus for regional fire agencies.
Air resources remain active in supporting ground-based firefighters to meet suppression objectives. For those seeking real-time updates on air quality and smoke levels related to the incident, officials have directed the public to the InciWeb incident information page.
