Powell Tract (Cahokia)


This site is located 1.6 km north of Fairmont City in Madison County, Illinois. A six-period sequence of occupation has been established (Coleman 1974). The refuse pit (Feature 331) in which maize kernels were found, contained other organic materials such as hickory nut shells, squash seeds, as well as large amounts of potsherds from Period III--"the period of densest urban occupation on the Powell tract" (Coleman 1974:115).
