About this map

Gilman and Onarga anchor the eastern edge of this mid-2010s survey, where the rigid grid of Iroquois County section roads meets the diagonal passage of the railroad and Interstate 57. The landscape is dominated by large-scale agriculture, yet it preserves several localized points of interest for genealogists and local historians. Small settlements like Ridgeville and Thawville punctuate the western plains, while Delrey sits further south along the rail corridor.

Watercourses such as Prairie Cr and Spring Creek wind through the flat terrain, breaking the geometric precision of the township range. Several burial grounds are documented, including Onarga Cem, Thawville Cem, and the more secluded Lisk Cem. This record of the modern landscape shows how the original settlement patterns around the rail lines have persisted into the twenty-first century, even as transportation networks have evolved.
