Explore mounds and village sties occupied by the Oneota and Prairie Sioux
This National Historic Landmark was a large village and ceremonial site of the people who were ancestors of the Omaha, Iowa, Ponca and Otoe-Missouria tribes. The Big Sioux River, abudant game, fertile soil for gardens and access to pipestone made this land attractive to these people. It was a major trading site from about 1500 to 1700. Hundreds of burial mounds were once observed and many are protected at this site.
