Many of South Dakota's ghost towns are in the Black Hills, where gold was found in 1874. South Dakota Public Broadcasting counts at least 200 Black Hills mining communities that survive only as ghost towns, out of more than 500 settlements founded there since 1874. Some chased gold, like Rochford, laid out in 1878; others silver and lead, like Galena; and Tinton turned from gold to tin and was abandoned after a fire destroyed its mill in the 1950s.
East of the Hills the story is railroads and homesteads. Ardmore, near the Nebraska line, began in 1889 as a stop where trains took on water and had one resident in the 2020 census. Okaton grew up with the Milwaukee Railroad in 1906 and faded when the line closed and Interstate 90 passed it by. Scenic, beside Badlands National Park, was bought almost whole by a church in 2011. Farther east, small farm towns simply emptied: Lily dissolved in 2017 after its population reached zero, and a 2003 tornado left only foundations at Manchester.
What remains varies. Rochford still has a saloon and about ten residents, Galena keeps its 1882 schoolhouse, and at Spokane a barn, a house and the school stand in the national forest. Many prairie sites are private, best seen from the road.
