The River's headwaters were near Blowing Rock, North Carolina; it then flowed through Virginia, West Virginia, Ohio, Indiana, and Illinois. (Hansen, 1995). [ 4 ] The largest tributary to the Teays River was the Old Kentucky River (Teller 1991), which extended from southern Kentucky through Frankfort and subsequently flowed northeast, meeting ...

The Allegheny Plateau (/ ˌ æ l ɪ ˈ ɡ eɪ n i / AL-ig-AY-nee) is a large dissected plateau area of the Appalachian Mountains in western and central New York, northern and western Pennsylvania, northern and western West Virginia, and eastern Ohio. It is divided into the unglaciated Allegheny Plateau and the glaciated Allegheny Plateau.
The river's path traveled through modern-day West Virginia, Kentucky, Ohio, Indiana, and Illinois, finally emptying into the Gulf of Mexico, which at the time extended to southern Illinois. The glaciers of the Ice Age soon began to block the Teays, effectively damming the river and forming Lake Tight, near what is now Chillicothe, Ohio.
[1] Marine (1997) found five terrace levels along the rivers, but he had to conclude that the lake deposits found on them resulted from only two episodes of glacial damming. Deposits on the fifth and fourth terrace levels represent damming during a pre-Illinoian glaciation, whereas the third- and second-terrace-level deposits represent damming ...
Till plains are large flat or gently sloping areas of land on which glacial till has been deposited from a melted glacier. In some areas, these depositions can be up to hundreds of feet thick. The morphology of the till plain is generally reflective of the topography of the bedrock below the glacier. Another term for till plain is ground moraine.
Since glacial till is highly fertile soil, agriculture on the glacial till plains is very productive. The region has gently rolling moraine hills left over from the retreating glaciers, as well as small sandy ridges , which were formed as coastal dunes during periods in which Lake Erie was higher than it is today (14,000-12,000 years ago).
