Cahokian Neighborhood Dynamics: New Geophysical Data from Rouch Mound Group and Rattlesnake West Neighborhoods
New geophysical surveys at Cahokia Mounds reveal that peripheral neighborhoods, such as the Rouch Mound Group and Rattlesnake West, mirrored the architectural and infrastructure patterns of Cahokia's densely populated Downtown Precinct. By analyzing structure length and width ratios from these areas alongside datasets from the Cahokia and East St. Louis precincts, researchers identified shifts in neighborhood density over time. This noninvasive approach provides deeper insights into how communities on the outskirts adopted and adapted Cahokia's urban planning, offering a clearer picture of its societal organization.
High Resolution Lidar Drone Imagery Assessment of the Rattlesnake Mound Complex at Cahokia, Illinois, USA
A high-resolution lidar drone survey of the Rattlesnake Mound Complex at Cahokia Mounds State Historic Site has revealed new details about a series of low mounds surrounding the primary structure, with only two previously documented. The study also assessed erosion damage caused by unfilled trenches from Moorehead’s 1927 excavation and uncovered new findings related to bundle burials and a 'spirit house' within Rattlesnake Mound. By combining lidar imagery with aerial photographs, researchers provided unprecedented insights into the site's structure and preservation challenges.
Reimagining the Development of Downtown Cahokia Using Remote Sensing Visualizations from the Western Edge of the Grand Plaza
Remote sensing visualizations from the western edge of Cahokia's Grand Plaza reveal significant insights into the development and transformation of Downtown Cahokia, Eastern North America's first American Indian city. The study identified sequences of monument construction and architectural changes in domestic and special-use structures without excavation, providing a detailed occupational history spanning the 9th to 14th centuries CE. Magnetometer and electromagnetic induction surveys, combined with LiDAR-derived visualizations, offered new information on the nature and sequence of earthwork constructions and plaza delineation, beginning in the early 11th century CE. This multi-scalar approach allowed researchers to trace important changes in Downtown Cahokia's history, contributing to a deeper understanding of its vibrant urban landscape.
Evaluating narratives of ecocide with the stratigraphic record at Cahokia Mounds State Historic Site, Illinois, USA
A stable ground surface at Cahokia Mounds, preserved from the Mississippian Period (AD 1050–1400) to the mid-1800s, contradicts the wood-overuse hypothesis that blamed deforestation for increased flooding. This challenges long-standing narratives of ecocide, demonstrating that pre-Colombian ecological changes do not necessarily lead to geomorphic alterations. The study employed stratigraphic analysis around an earthen mound in Cahokia Creek's floodplain, revealing no evidence of erosion or instability during Mississippian occupation, thus invalidating the hypothesis linking upland deforestation to downstream flooding.
Exploring the Land of Lincoln: The Essential Guide to Illinois Historic Sites
Dr. Charles Titus's book, 'Exploring the Land of Lincoln: The Essential Guide to Illinois Historic Sites,' offers a comprehensive exploration of Illinois' diverse historical landscape, focusing on 20 key sites that span from pre-colonial times to the modern era. The work stands out for its chronological organization and elegant prose, providing both geographical context through maps and timelines, as well as rich narrative descriptions of each site's significance. Notably, it includes Cahokia Mounds State Historic Site, one of the most significant prehistoric Native American sites in North America, alongside other pivotal locations such as Starved Rock, Fort de Chartres, and Lincoln-related landmarks. The book is supported by meticulous citations and enhanced with pen-and-ink illustrations, making it an invaluable resource for understanding Illinois' layered history. While subjective in its site selection, the guide effectively balances accessibility with depth, serving both academic and general audiences.
A Conversation with Lisa Overholser, Director of the St. Louis Storytelling Festival
The St. Louis Storytelling Festival, established in 1980, has successfully engaged over 18,000 individuals annually, including 15,000 school students from pre-K to grade 12, through its school and public programs. The festival's outreach extends to prisons, youth detention centers, and hospitals, demonstrating its broad accessibility and impact on diverse communities. Hosted at UNESCO World Heritage Sites like Cahokia Mounds State Historic Site and other significant venues, the festival leverages storytelling as a tool for community education and economic development, aligning with its land-grant mission through the University of Missouri Extension's Community Arts Program.
Exploring New Cahokian Neighborhoods: Structure Density Estimates from the Spring Lake Tract, Cahokia
A recent magnetometry survey of the Spring Lake Tract at Cahokia Mounds State Historic Site, conducted in 2015, reveals significant insights into the site's occupational history. The study identifies a previously unknown borrow pit and demonstrates an increase in building density during the transition between the Terminal Late Woodland and Lohmann phases. Additionally, it shows dense occupation between the Lohmann and Stirling phases, with potential increases in habitation during the Moorehead phase. This challenges previous understandings of domestic space use in Cahokia's late occupational history. The research combines gradiometer data with test excavations and statistical analyses to estimate structure density and area.
Misconceptions of “Stupendous Antiquities” : Native American Mounds, Euro-Americans, and Racial Ideas
A study reveals that the neglect of Indigenous mound sites, such as Cahokia near St. Louis, Illinois, stems from 19th-century Euro-American racial attitudes and misconceptions. Despite Cahokia's grandeur—comparable to London in size by 1200 AD and featuring advanced engineering, urban planning, and astronomical knowledge—the site was not protected until 1964 due to widespread dismissal of Indigenous capabilities. Scholars often attributed these structures to non-Indigenous cultures or aliens, reinforcing stereotypes that Indigenous peoples were incapable of such achievements. This research demonstrates how racial biases led to the degradation and neglect of these sites, highlighting the intersection of antiquities preservation with historical perceptions of race.
Cahokia's Rattlesnake Causeway
Recent archaeological excavations at Cahokia Mounds State Historic Site, Illinois, have uncovered evidence of a significant earthen causeway, the Rattlesnake Causeway. This 1-kilometer-long and 18-meter-wide structure was part of an early, planned city layout that connected Cahokia's central precinct to ridge-top mortuary mounds, reinforcing its sophisticated urban design. The findings reveal a grid-based plan with at least 104 earthen monuments, a large central plaza, and the causeway serving as a key landmark. This research sheds new light on the advanced engineering and spatial organization of one of North America's most complex pre-Columbian societies.
The Cahokia Mounds:
Cahokia Mounds State Historic Site, the largest prehistoric mound center in North America and a UNESCO World Heritage Site, was confirmed by Warren K. Moorehead's 1921–1927 excavations to be constructed by indigenous peoples between A.D. 1050 and 1350. Originally containing over 100 mounds used for rituals, elite residences, or tombs, the site faced destruction from urban development before Moorehead's work. His investigations, blending 19th-century techniques with contemporary methods, preserved the legacy of Cahokia while navigating social pressures. Reissuing his findings provides insight into this critical archaeological effort and the prehistoric civilization that built it.
