- Cahokia, an indigenous culture around 1050 CE near modern-day Collinsville, Illinois, was the most populous settlement in pre-Columbian North America. Scholars argue that both the vitality and demise of Cahokia were tied to the culture's relation to water, set by the geologic landscape of the Mississippi floodplain.
- 3.2: Classroom Activity
- This Classroom Activity focuses on identifying landforms in the Mississippi River floodplain by comparing geomorphological features from 1050 CE to the present through Google Earth. It intends to compare landforms in historical and contemporary maps while noting morphological changes. Additionally, it highlights the evolution of the floodplain's boundaries and the river channel's path, recommending the measurement of floodplain width at various locations for in-depth analysis.
- 3.3: Assignment
- This Assignment examines floodplain characteristics of alluvial channels, with a focus on the Mississippi River, detailing dimensions, inundation patterns, sediment processes, and human uses. It describes key erosional and depositional landforms, such as cut banks, meanders, natural levees, and point bars.
