Poplar City and Biggs anchor the northern landscape of this Central Illinois region, where a dense grid of county roads reveals a legacy of rural agricultural settlement. The southern edge is defined by the winding course of the Sangamon River, which marks the boundary between Mason Co and Menard Co. The lowlands north of the river, known as Herget Bottoms, are heavily managed by a system of drainage features including the Herget Drainage Ditch, Perry Slough, and Wash Lake Slough, illustrating the extensive reclamation of river bottomlands for farming.
