The Mississippi River meanders through this portion of Marion County, creating a complex landscape of islands and sloughs. High ground to the southwest transitions into a sprawling floodplain dominated by Goose Island and Bay Island. The northern reach of Hannibal anchors the map, while smaller settlements like Huiskamp, Helton, and Mungers dot the rural interior. This 2015 edition provides a detailed look at the local topography before modern developments altered the drainage patterns of the Fabius River and South River.
