The Kaskaskia River snakes across the heart of this landscape, its winding course defining the transition between the townships of North Okaw and East Nelson. At the turn of the millennium, the area reflects a deeply rooted rural infrastructure where the small settlement of Cooks Mills and the nearby Cooks Mills Consolidated Oil Field highlight the dual reliance on agriculture and subterranean resources. The presence of numerous active oil wells and the North Mattoon Oil Field in the south underscores the industrial character of this corner of Illinois.
