About three quarters of this area lies in the Interior Plains. Eastern Ohio, excepting the lakefront, is within the Kanawha Section of the Appalachian Plateaus, part of the Appalachian Highlands. Most of the Interior Plains here are in the Central Lowland, but southwest Indiana is in the Interior Low Plateaus.
The northwest corner of Indiana fronts Lake Michigan and much of Ohio's north consists of Lake Erie shoreline.
These states are in the part of North America in which English-speakers and Christians are the majority.
Indianapolis, Indiana, is in the heart of the Till Plains, and--though the state's capital--is better known for its 500 mile car race.
On the Ohio's River's right bank is Cincinnati, Ohio. The river marks the southern bound of the Till Plains. Beyond it is the Lexington Plateau.
Columbus, Ohio's capital, is at the junction of two of the Ohio's tributaries, and within the Till Plains.
Cleveland, Ohio, lies in the narrow south shore extension of the Eastern Lake Section, where the Cuyahoga River enters Lake Erie. It has cleaned up since the notoriously polluted river mouth caught fire decades ago.
Speakers of Algonquian languages like Kickapoo and Miami lived in western Indiana before the arrival of Europeans. The multi-ethnic resistance religion and rebellion led by Pontiac, spread through this area. A famous resistance religion, led by the Shawnee, Tecumseh, was centered in Tippecanoe, Indiana, also called Prophetstown.
The French were the first Europeans in the area, traveling by waterways. The English-speakers claimed the area after the United Kingdom defeated France, and subsequently violently displaced the indiginous inhabitants.
