    Imagine this site as it once was – a large village and ceremonial site of the ancestors of the Omaha, Ponca, Iowa and Oto-Missouria tribes, known as the Oneota people. The Oneota were attracted to the site by the Big Sioux River, abundant game, fertile soil and access to pipestone. The land was inhabited from 900 A.D. to 1720 A.D. and was a major trading site from about 1500 to 1700.

    Take a self-guided walking tour along mowed trails to view protected burial mounds, village sites and other features of cultural interest.

    Blood Run is located in Iowa and South Dakota along the Big Sioux River and Blood Run Creek. South Dakota is developing the Good Earth State Park at Blood Run and the Iowa Department of Natural Resources is working on a study to develop a companion park in Iowa.
