About this map

Mississippi River bottomlands dominate this landscape on the Illinois-Missouri border, where a complex network of levees and sloughs protects agricultural tracts. The intricate water system includes The Sny and the Sixmille Settling Basin, indicating the extensive engineering required to manage the floodplains of the late 20th century. Settlement is concentrated on the higher ground of the eastern bluffs at Pleasant Hill, while the riverfront near Clarksville is defined by the massive infrastructure of Lock and Dam No 24.

Conservation efforts are prominent across the islands and backwaters, with significant portions of the land dedicated to the Mark Twain National Wildlife Refuge and the Upper Mississippi River State Conservation Area. Genealogists will find the Martinsburg Cem and Sapp Cem situated near the valley edge, marking the historical footprint of early residents near the vanished site of McIntosh and the rugged Jeager Knob.
