Detailed explanation-1: -The Cahokians built three types of earthen mounds-pyramid-shaped platform mounds, which had flat tops that served as bases for ceremonial buildings or residences of the elite, and conical and ridge-top mounds, both of which were used for burials of VIPs and, in some cases, victims of sacrificial rituals.

Detailed explanation-2: -The Cahokia Mounds State Historic Site /kəˈhoʊkiə/ (11 MS 2) is the site of a pre-Columbian Native American city (which existed c. 1050–1350 CE) directly across the Mississippi River from modern St. Louis, Missouri.
