Onarga and the southern edge of Gilman anchor the northwestern corner of this Iroquois County landscape, where the flat agricultural terrain is defined by a dense grid of township and county roads. The eastern half of the map is shaped by the meandering course of Spring Creek and its tributaries, including Shavetail Creek and Little Mud Creek, which provide the primary topographic relief in an area dominated by large-scale farming.
