RAPID CITY, S.D. – Wildfires driven by lightning storms and challenging weather conditions have prompted emergency closures and response efforts across the region.

Devils Tower National Monument announced a full closure as firefighters contend with an active blaze nearby. “Devils Tower National Monument is currently closed due to a wildfire,” monument officials stated on social media on August 1st.

Meanwhile, further west in Sheridan County, Wyoming, crews continue fighting the Lumin Fire, which has burned approximately 7,200 acres. According to Sheridan County Health, a series of lightning storms moved across the region on Friday, July 31, 2026, igniting multiple fires north of Clearmont, Wyoming, near the junction of SR-Buffalo and Passaic Roads.

While two of the initial fires were quickly contained, the Lumin Fire expanded rapidly due to weather and fuel conditions. The terrain and local fuels have made containment difficult, with the fire spreading across private and state lands. While structures in the area have been threatened, officials confirmed that none have been lost. Firelines have been constructed around the perimeter, though crews face significant weather challenges.

A Wyoming Type 3 Incident Management Team under Incident Commander Jon Warder was ordered to assume command of the incident. Fire suppression efforts involve local resources from the Clearmont Fire District, all Sheridan County Fire Districts, Sheridan County Road & Bridge, Campbell County Fire, Wyoming State Forestry Helitack, fixed-wing aviation, and heavy equipment contractors including CDS and Fischer.

Officials noted that SR-Buffalo and Passaic Roads will experience increased traffic from fire personnel and requested that only necessary travel take place in the area.

Authorities also issued a warning regarding the use of unmanned aircraft near active fire operations. When drones are flown near a wildfire, firefighting aircraft are forced to suspend operations immediately due to the risks posed to pilots flying low in reduced visibility. “If you fly, they can’t,” officials emphasized, adding that grounded aircraft grant the fire more time to grow, placing crews, homes, livestock, and communities at greater risk.

The Clearmont Fire District extended appreciation to local supporters including the Cowboy Bar & Grill, McDonald’s in Buffalo, Wyarno Bar & Grill, Padlock Ranch, Sheridan Ranches, and Coca Cola Bottling Company, noting that no additional donated items are needed at this time.
