Pleasant Hill and Nebo anchor this portion of the Illinois landscape, where the flatlands of the Mississippi floodplain meet the deeply dissected bluffs of the interior. The contrast in terrain is immediate, with the western edge defined by drainage features like Crooked Slough and Dolman Pond, while the eastern portion is dominated by narrow ridges and steep hollows. The distribution of family and community burial grounds across these ridges is remarkable, serving as a primary record of rural settlement patterns.
