The Mississippi River valley north of Hannibal dominates this 2012 survey, revealing a landscape defined by complex hydrology and family history. The river's path is marked by a network of chutes and backwaters, including Texas Chute, Eastern Slough, and the Rock Ridge Slough, which frame numerous islands like Fabius Island and Bay Island. On the Missouri side, the South River Levee stands as a critical piece of infrastructure, protecting the low-lying agricultural lands and small settlements like Huiskamp and Helton from the seasonal fluctuations of the river system.
