Summit Ridge forms the backbone of this driftless area landscape, where the Elroy Sparta State Trail follows an old rail grade through the northern valleys. The settlement of St Marys serves as a central point in Jefferson township, while the village of Norwalk sits at the eastern edge where several local roads converge. This 1980s terrain is defined by a dendritic drainage pattern of valleys such as Lyon Valley, Halls Valley, and Spring Valley, each carved into the high plateau.
