BUFFALO GAP, SD – Officials declared the 79 Fire 100% contained late Tuesday night after the grass fire scorched 5,408 acres in Custer County. While the perimeter is now secure, state and local resources will remain on-site for several days to monitor for hotspots and ensure the flames do not reignite.

The fire broke out on April 11 near mile marker 37 on Highway 79, located just north of Buffalo Gap. Fueled by dry conditions and high winds, the blaze experienced explosive growth, surging from an initial 500 acres to more than 5,000 acres.

Governor Larry Rhoden declared a state of emergency on April 11 to bolster the response for the region near Rapid City.

“Keeping South Dakotans safe is my number one priority, and this emergency declaration will provide the resources firefighters need to get control of this fire,” Rhoden said. “I’m grateful for their dedication and bravery in keeping everyone safe.”

The emergency declaration authorizes the use of the state fire suppression fund to cover costs, ensuring local agencies have the financial support required for a long-term response.

Throughout the week, a coordinated effort involving federal, state, and local firefighting assets, including aircraft, worked to halt the spread. Although the fire moved rapidly toward the east in its early stages, crews successfully protected structures and prevented injuries.

State and local resources will continue to check on the fire for several days.
