Historical Markers in
Buffalo County, South Dakota

South Dakota is the only state in the U.S. that has never had an earthquake.
Buffalo County, South Dakota, has a rich and diverse history that dates back thousands of years. Before European settlement, the region was home to various Native American tribes, including the Lakota Sioux. These tribes thrived on the Great Plains, relying on bison for sustenance and utilizing the vast grasslands for hunting and gathering.

In the mid-1800s, American settlers began to arrive in the area due to the Homestead Act of 1862, which offered free land to those willing to cultivate it. This led to the establishment of farming and ranching communities in Buffalo County. However, conflicts between settlers and Native Americans, particularly during the Dakota War of 1862, disrupted the peace in the region.

Buffalo County was officially organized in 1883, taking its name from the bison herds that once roamed the area. The county seat was established in Gann Valley, which became a hub for trade and commerce in the region. Agriculture, mainly wheat farming and cattle ranching, became the primary economic activities.

In the early 20th century, Buffalo County experienced both growth and challenges. The expansion of the Chicago, Milwaukee, St. Paul & Pacific Railroad in the early 1900s brought increased transportation opportunities and access to markets for local farmers. However, the Dust Bowl and Great Depression in the 1930s severely impacted the agricultural industry, leading to economic decline.

Today, Buffalo County continues to be a rural community with a strong agricultural heritage. The county remains sparsely populated, but its residents take pride in preserving their history and supporting local businesses and agriculture.
