The Sangamon River carves a winding path along the boundary between Mason and Cass counties, creating a complex floodplain of sloughs and lakes. The northern reach is defined by the slow-moving waters of Anderson Slough, McHenry Slough, and Fish Lake, while the southern terrain rises into more dissected hills. The small community of Newmansville anchors the southeastern corner, serving as a focal point for researchers interested in the local rural landscape.
