The boundary between Jo Daviess Co Carroll Co divides a landscape defined by the branching tributaries of the Plum River. In the northern section, the village of Massbach sits near the headwaters of Derinda Creek, while the settlement of Pleasant Valley occupies the valley floor where the Muddy Plum River joins the main stem. This mid-1980s topography reveals an upland region characterized by deep creek drainages and agricultural plots, punctuated by small rural centers and isolated industrial sites like a Quarry near the eastern edge.
