Archaeoastronomy and Landscape Archaeology at Cahokia

New research reveals that Cahokia, the largest Native American city north of Mexico during the Mississippian era, features earthen mounds strategically aligned with astronomical phenomena and landscape markers. Specifically, Monks, Rattlesnake, Powell, and other mounds are found to be oriented toward solar, lunar, and Milky Way trajectories, intersecting prominent bluffs that likely served as horizon references. This discovery was achieved using LiDAR imagery, historic documents, ethnohistoric data, and archaeological evidence, providing unprecedented insight into the sophisticated spatial planning of this ancient civilization.
