The Sangamon River meanders through the central Illinois prairie, marking the winding border between Sangamon County and Christian County. This 2018 survey documents the rural agricultural landscape surrounding Illiopolis and Mount Auburn, where rectilinear section lines define a grid of farm roads such as Lanesville Rd and Mechanicsburg Illiopolis Rd. Small settlements like Lanesville, Saunders, and Haynes appear as quiet junctions amidst the vast acreage of central Illinois farmland. The map reveals a high concentration of historic burial sites, including the Sangamon County Home Cem, Bethel Cem, and Milligan Cem, which are vital for genealogical research. Notable terrain variations break the flat horizon, specifically the elevations at Yellow Hammer Knob, Blind Horse Ridge, and Hampton Bluff overlooking the river valley.
