About this map

The Mississippi River forms a dynamic boundary between Missouri and Illinois in this detailed 2017 study, where the river's shifting hydrology is marked by numerous islands and side channels. Large landforms like Powers Island, Billings Island, and Woods Island are separated from the main channel by features such as Doolan Chute and Billings Slough. This fluvial landscape is mirrored by a complex network of man-made drainage systems on the western plains, including the North-Cut Ditch and Circle Ditch.

Small settlements and local history landmarks are concentrated near the roadway network. The community of Unity sits near the western edge of the map, while Lusk is positioned along the riverbank to the southeast. Genealogists can identify several local burial sites, such as Prince Cem, Pollard Cem, Unity Cem, and Cason Cem, providing essential points of reference for family histories in Scott and Alexander Counties. The map effectively documents the intersection of rural agriculture and river-driven geography.
