Upper Iowa River

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

Backhaus SiteThese sites contain glass beads, iron knives, brass ornaments, and other historic trade goods, along with traditional Oneota goods such as Allamakee Trailed pottery. 

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 Lane Enclosure

Lane Enclosure SiteThe Lane Enclosure, situated on the Hartley Terrace of the Upper Iowa River, was built a few hundred years before the Oneota culture. It features a 72-meter (236-foot) diameter earthwork approximately four feet in height with an interior ditch. Oneota people resided at the site around AD 1400-1500 and again in greater numbers and probably on a year-round basis around 1650. Archaeologists found European trade goods, bones of deer, elk, and fish, and maize in the Oneota storage pits.

The Wild Site

Little Desert SiteThe Wild Site was a small Oneota village in the river floodplain near the Hartley Terrace. Its Oneota occupation dates to AD 1400-1500. The site was probably a summer farming village, with occupation possibly extending into late fall or early winter.

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.
