14. Ancient River Channels
Beneath the Black Belt’s farmland, the soil conceals old riverbeds and oxbow lakes, remnants of the region’s dynamic hydrological history. The Alabama and Tombigbee rivers have long shaped and reshaped their floodplains, creating abandoned channels, oxbow lakes, and shallow swamps (alblackbeltheritage.com). These features influence modern land use, affecting both agriculture and flooding patterns. For example, the Cahaba River, Alabama’s longest free-flowing river, contributes to the region’s rich biodiversity and has historically been a vital water source.
