Oneota sites on the Upper Iowa River and its tributaries are the "type sites" of the Orr focus (now Orr phase) and thus the first archaeological sites that were identified as likely those of the historic period Ioway. Their artifacts and house styles are similar to those of slightly earlier Oneota sites around La Crosse, Wisconsin. Most of the Orr phase sites investigated to date have been cemeteries adjacent to Ioway village sites. The villages probably were seasonally occupied and had nearby gardens, and most were situated on stream terraces or floodplains.

More recent excavations at sites with Oneota materials including the Backhaus, Wild, and 'Little Desert' sites promise to provide further details of Oneota lifeways in northeast Iowa.

The Wild Site

Oneota people at the site built large oblong structures with central hearths and many storage pits. Some of these pits contained corn. The Wild site was discovered buried beneath 1 meter of alluvial deposits, suggesting that the Upper Iowa River floodplain may hide more Oneota villages.
