North Henderson and Rio anchor this landscape where the boundaries of Mercer, Knox, and Warren counties meet. The terrain is defined by the dendritic drainage patterns of North Henderson Creek, Middle Henderson Creek, and South Henderson Creek, which carve through the agricultural tablelands of western Illinois. For genealogists, the map is particularly rich in small burial grounds and family landmarks, including Mount Vernon Cem, Deatherage Cem, and Rice Blue Cem.
