About this map

The Keokuk Dam anchors this mid-1930s landscape, where the Mississippi River widens into Keokuk Lake. On the Illinois side, the riverbank is a complex network of channels and islands including Hackley Island, Taylor Island, and Kauffman Slough. The topography transitions from the alluvial bottomlands of Wilcox and Rocky Run to the dissected uplands of Montebello and Sonora, revealing a rural infrastructure of one-room schools such as Froggy Sch and Green Plain Sch.

Transportation patterns are dominated by the Toledo Peoria and Western railroad and early highways like State Highway No. 9. Local life centers around crossroads settlements and country churches, notably Sandhill Ch and Bethlehem Ch. This survey, compiled in part from Army Air Corps aerial photography, provides a clear view of the Hancock County shoreline before modern development altered these drainage systems.
