About this map

The Mississippi River forms the central character of this riverine landscape, serving as the border between Illinois and Iowa. Along the southern banks, the riverfront settlements of Dallas City and Pontoosuc are defined by their proximity to the water and the rising terrain of The Ridge. The topography here shifts from the wide, island-studded channel containing Dallas Island and Grape Island to the intricate drainage networks of the north, where the Skunk River meanders through Lee County toward its confluence with the Mississippi.

Genealogists will find a high density of small burial grounds scattered across the agricultural uplands, including the Miller Family Plot, Mohnike Cem, and South Walker Cem. These sites, along with older road alignments like Old HWY 61, point to the long-established rural community structure surrounding Spring Grove and Wever. The map captures the complex hydrology of the area, from the engineered Rogers Ditch to the natural oxbows and ponds like Round Lake and Roseum Pond that dot the river valley.
