Related mounds

Until the 19th century, a series of similar mounds was documented as existing in what is now the city of St. Louis, some 8 mi (13 km) to the west of Cahokia. Most of these mounds were leveled during the development of St. Louis, and much of their material was reused in construction projects.

The lone survivor of these mounds is Sugarloaf Mound. Located on the west bank of the Mississippi, it marked the initial border between St. Louis and the once autonomous city of Carondelet.

One of the largest Mississippian sites is Kincaid Mounds State Historic Site, located in Massac and Polk counties in southern Illinois. It is 140 mi (230 km) southeast of Cahokia, located in the floodplain of the Ohio River. With a total of 19 mounds at the complex, it is considered the fifth-largest Mississippian site in terms of the number of monuments. It is believed to have been a chiefdom, as an elite burial mound was among those found. The site is designated as a National Historic Landmark.
