About this map

Gilman and Onarga anchor the eastern edge of this East Central Illinois landscape, where the flat agricultural terrain is defined by a rigid grid of country roads. The transition between Iroquois County and Ford County is visible on the western margin, a boundary that cuts through the open prairie. Small rural settlements like Ridgeville and Thawville serve as local hubs, connected by an extensive network of numeric routes such as Co Rd 1200 N and E 1500 North Rd.

Waterways like Prairie Cr and Spring Creek meander across the plains, offering the only break in the geometric precision of the fields. For genealogists and local historians, several burial sites are preserved here, including Onarga Cem, Thawville Cem, and the more isolated Lisk Cem. This record of the 2021 landscape captures the enduring pattern of Illinois prairie farming and the small towns that support it.
