About this map

The Blanchard River and Sandusky River drain this portion of the Till Plains, where the agricultural grid is punctuated by established college towns and industrial rail hubs. Higher education is a cornerstone of the region, anchored by Bluffton College in the northwest and Ohio Northern University at Ada. The landscape is defined by its drainage engineering, featuring an extensive network of ditches and runs such as Tiderishi Ditch and Cottonwood Ditch that support the fertile farmland.

Conservation areas provide a contrast to the surrounding fields, most notably the expansive Killdeer Plains State Wildlife Area and Big Island State Wildlife Area. Transportation networks are dominated by the heavy rail lines of Conrail and the Norfolk and Western, which serve several small settlements like Dunkirk, Forest, and Upper Sandusky. To the southwest, the recreational waters of Indian Lake and its associated Indian Lake State Park mark a distinct shift from the inland plains.
