The Blood Run site is a prehistoric and protohistoric Oneota cultural settlement
adjacent to the Big Sioux River in Lincoln County, South Dakota and Lyon
County, Iowa. In 1987, the State Historical Society of Iowa, through cooperative
efforts of the Iowa Natural Heritage Foundation and local landowners, acquired
a portion of the site.
Blood Run is the largest of the known Oneota cultural sites extending
across 650-1250 acres in Iowa and approximately 1000 acres in South Dakota.
