Black Ridge

Fire Start, Size and Growth

Start Date/Time/Location: The Black Ridge Fire ignited around 4:00 p.m. MDT on Monday, May 25, 2026. The fire is located approximately 8 miles northeast of Richfield in Lincoln County, Idaho.
Size and Containment: As of the latest updates over the past 72 hours, the fire has burned an estimated 1,500 acres and has been successfully brought under control.
Fuels, Growth and Rate of Spread: Burning primarily in grass and brush, the fire initially spread rapidly upon ignition. At its peak, fire behavior included seven to eight active fingers moving around and through remote lava blisters in the area.
Containment Efforts: Wildland firefighters and fire managers, including resources from the Bureau of Land Management (BLM) Idaho Fire and the National Interagency Fire Center (NIFC), actively responded to the incident. Access to the fire proved to be a significant logistical challenge for ground crews due to the rugged volcanic terrain and lava rock formations. Despite these challenges, crews successfully halted forward progress and brought the fire under control.

Crews have successfully managed the perimeter despite the challenging volcanic terrain, and ongoing efforts are focused on monitoring and patrolling the area.

Cause and the Role of Weather and Climate

Cause: The Black Ridge Fire was caused by a lightning strike during the busy Memorial Day holiday weekend.
Weather and Climate: Southern Idaho is experiencing dry conditions typical of the early summer fire season. The combination of dry grass and brush fuels, coupled with seasonal breezes and windy, dry conditions, created an environment that was highly conducive to rapid fire growth across the region upon ignition.
