State Line Road serves as the dividing line between Iowa and Missouri on this topographic study, where the rolling hills of Appanoose and Putnam counties meet. The small settlement of Mendota occupies the center of the Missouri side, positioned near Mendota Cemetery and the headwaters of Sandy Creek. To the south, Howland sits atop a ridge overlooking the winding drainage of North Blackbird Creek, while Cincinnati anchors the northern Iowa section.
