The Turkey River valley dominates this mid-1960s Iowa landscape, where the settlements of Clermont and Elgin serve as focal points for the surrounding townships. The route of the Chicago Rock Island and Pacific railroad traces the river's winding path through Pleasant Valley, connecting smaller locales like Brainard and the rural crossroads of Illyria. The topography is defined by significant drainage systems including Otter Creek, Beaver Creek, and Mink Creek, which cut through the uplands to meet the Turkey River.
