Ancient Hopewell Earthwork on the Wabash River Determined to be Oneota Sioux

Prehistoric Antiquities of Indiana, Lilly, 1937

The village and burial site near the mouth of the Wabash yielded so many artifacts similar to the Oneota culture, such as limestone disk pipes, copper ear spools, tubular beads, and characteristic triangular arrow points, that Siouan relationship seems almost certain. Probably the village at Bone Bank [Posey County, Indiana] and the citadel at Merom, both on the lower Wabash, were also Siouan sites.
