Richard Edging excavated a location along this geographic feature called the Turk Site, which was occupied around the Dorena and Medley Phases. Holly Bluff and Medora were established near this feature during a successor culture to the Marksville, the Plaquemine culture. "Cooking balls" were uncovered near this feature at a site whose semicircular embankments extended out from a central (-5[1])plaza, called Poverty Point. A (*) culture named for this feature preceded (10[1])the Taensa (-5[1])and Natchez and created a spear-throwing game called chunkey. This feature names a Woodland Period culture that created "America's Woodhenge" and dozens of raised earth mounds, including Monks Mound. The settlement of Cahokia was founded on, for 10 points, what American (10[1])river that passes (10[1])through St. Louis? ■END■
