Rio and North Henderson anchor this western Illinois landscape where three counties — Knox, Mercer, and Warren — converge. The terrain is defined by the branching tributaries of Henderson Creek, including N Henderson Cr, Middle Henderson Cr, and S Henderson Cr. This network of waterways is complemented by smaller bodies such as Railroad Pond and Glass Lake, indicating a legacy of transport and local drainage management.
