Cahokia regional vicinity and Horseshoe Lake watershed, shown as the black dashed line. Coring sites are indicated by red stars. Cahokia largely consists of deposits that are within the large circle; black rectangles indicate the location of major Cahokian mounds. Black dots show the locations of small archaeological deposits (<2 mounds) occupied contemporaneously with Cahokia (approx. 1000-1400 CE; Milner, 1998).
