Orion and Sherrard anchor this Western Illinois landscape, where the agricultural plains of Henry, Rock Island, and Mercer counties meet. The terrain is defined by the incision of the Edwards River and its tributaries, including Camp Creek and Coal Creek, which create a series of gentle valleys and ridges. Small rural settlements like Swedona and Ophiem reflect the region's deep-rooted farming heritage, connected by a systematic grid of county roads such as Knoxville Rd and Sherrard Orion Rd.
