Description: Walworth County is unique in South Dakota. There are few places in the United States that can boast of the heritage of the land and people like this county. As early as 1823, hunters, trappers, and later Gen. William Ashley came up the Missouri River with the intent to establish a post. By 1869, some of the Sioux tribes signed a treaty with the US government, giving up a defined land district that included what became Walworth County.
