The Homestake Mine, located in the Black Hills of South Dakota, was the largest and deepest gold mine in North America, producing over 40 million ounces of gold during its operation.
Tripp County, South Dakota, is located in the central region of the state. It was officially established in 1873 and named after the prominent politician and lawyer Bartlett Tripp. The area had long been inhabited by various Native American tribes, including the Lakota Sioux, but colonization began with the arrival of European settlers.

During the late 19th century, Tripp County experienced a surge in population as homesteaders were attracted to the fertile land and opportunities for farming and ranching. The arrival of the railroad in the area further facilitated settlement and economic growth. Small towns like Winner, which eventually became the county seat, began to emerge as commercial hubs.

Tripp County played a significant role in the development of livestock farming, particularly cattle ranching. The introduction of barbed wire fences in the late 1800s allowed for the expansion of ranches and the establishment of cattle trails. The county became known for its high-quality beef production and hosted various cattle drives during this time.

In the early 20th century, Tripp County faced challenges such as droughts and economic downturns, impacting its agricultural sector. However, efforts to modernize and diversify the local economy were successful, enabling the county to recover. Today, Tripp County remains a rural area with a primarily agricultural economy, while also being a gateway to recreational activities, including hunting and fishing, attracting visitors to its scenic landscapes and natural beauty.
