Yankeetown people lived near the mouth of the Wabash River during the Late Woodland/Mississippian period. They were the residents of the Foster site.
They produced distinctive, well made, and well-fired pottery. Their smoothed and, less commonly, cordmarked jars were tempered with grog (crushed fired clay). But what really distinguished these people's pottery from that of their ancestors, and from that of their descendants, too, was how they decorated their jars.
Common vessel forms were jars, bowls, and sometimes, pans. Large vessels had lugs or loop-shaped handles.
Other diagnostic artifacts from Foster included triangular arrowheads; abraders, celts, and hammerstones; beads and human figurines made from pottery; and disks and pendants made from cannel coal (a kind of carvable, hard, smooth coal).
The ancient Native people who lived at this house grew corn, goosefoot, maygrass, and little barley in nearby agricultural fields. They also collected hickory nuts, pecans, walnuts, and acorns, and several types of fruits, including grapes, blueberries, and raspberries They ate deer, raccoon, beaver, gray squirrel, opossum, bird, turtle, snake, and fish.
