About this map

The Mississippi River forms a complex maze of islands and sloughs along the Illinois-Missouri border, shaping the lowlands west of Pleasant Hill. The hydrological engineering of the valley is evident through features like the Sixmile Cr Diversion Ditch and the Sixmile Settling Basin, designed to manage the flow of The Sny and its many tributaries. These waterways, including Cocklebur Slough and Ransom Slough, define a landscape where dry ground is often found only on named rises like Jaeger Knob.

Family history is preserved in several upland burial grounds, including Emert Cem, Wells Cem, and Sapp Cem, situated on the bluffs overlooking the river bottoms. Small settlements such as McIntosh and Roblee provide anchors for researchers tracing the development of Pike and Calhoun Counties. The map also documents numerous river islands such as Pharrs Island and Middleton Island, illustrating the shifting nature of the river channel over time.
