Ohlman stands as the primary settlement in this corner of Central Illinois, situated at the junction of Montgomery and Christian Counties. The landscape is defined by its agricultural grid, centered around the Missouri Pacific Conrail line that cuts diagonally through the northern territory. Local history is anchored by rural landmarks such as Shiloh Ch and Rosamond Grove Cem, which serve the surrounding townships of Rosamond and Audubon. The terrain transitions from flat prairie in the north to a more dissected drainage system in the south, where Ramsey Creek and Elliott Creek carve into the upland. Notable surveying history is present in the form of the Third Principal Meridian, which forms the eastern boundary of the map, marking a fundamental line in the settlement and division of Illinois lands.
