Bismuth is a ghost town in the Black Hills of Custer County, South Dakota, United States.

[2] The region surrounding Bismuth was a hunting ground and sacred territory of the Western Sioux, as well as the Cheyenne, Kiowa, and Arapaho.

[3] The 1868 Treaty of Fort Laramie guaranteed Black Hills land rights to the Sioux and Arapaho.

Native groups resisted the thousands of white settlers that came to the area over the next year; the conflicts culminated in the Black Hills War in 1876.

[3] The 1874 gold rush and subsequent land seizure gave rise to a series of boomtowns, mines, and other settlements in the region, including Bismuth.

Ponderosa pines are the most common tree, but spruce, aspen, birch and oak also grow in the region.

Native bird species include mountain bluebirds, western tanagers, goshawks, and ospreys.
