Coteau des Prairies, a prominent glacial upland, dominates this landscape in northwest Iowa. This landform directs the flow of Stony Creek as it meanders southward, eventually crossing the border between Dickinson County and Clay County. The area is characterized by its organized agricultural grid, with section lines marked by routes like Co Hwy A30 and 270th St. Local history is preserved at the Excelsior Township Cem and the Westport Cem, which serve as quiet landmarks for the rural townships of the region. The presence of Stony Lake in the northwest corner highlights the remaining glacial depressions that punctuate this high prairie terrain, showing how water and topography dictated the placement of early farmsteads and transport corridors.
