All mound information, unless otherwise noted, is taken from "The Cahokia Atlas: A Historical Atlas of Cahokia Archaeology", written by Dr. Melvin L. Fowler, Ph.D.(1989).
Not all mounds have names.

Mound 92

Just to the south of Mound 91 and cut by the modern highway and its ditches is another possible mound, Mound 92. It shows only as a slight elevation just below the 128-meter (419.9 foot) contour line. On some air photos there is a semicircular white area that suggests a mound disturbed by modern construction and cultivation. Its presence could be tested by cutting an east-west trench paralleling the highway ditch starting at about N20W746. If a mound is confirmed here, the four mounds (43, 44, 91, and 92) logically enclose a plaza, one designated the West Plaza (Fowler 1978a).
