The Sangamon River meanders across the southern landscape of this central Illinois quadrangle, defining the boundary between Sangamon Co and Christian Co. The village of Mount Auburn anchors the southeastern corner, where the Mount Auburn Cem and local street grids sit just north of Mosquito Creek. Further north, the grain-and-rail corridor is dominated by Illiopolis, a primary settlement situated along the railroad and the northern reaches of the Old River.
