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 Laurentide ice sheet (LIS) was a massive sheet of ice that covered millions of square miles, including most of Canada and a large portion of the Northern United States, multiple times during the Quaternary glaciation epochs, from 2.58 million years ago to the present.
In its advance to the Union City Moraine, the glacier crossed terrain free of ice except for a few scattered blocks northwest of Alexandria, but from Alexandria to eastern Delaware County it probably overrode thin debris-charged stagnant ice. Gravel-filled channels in the dead ice mass were not destroyed by the overriding glacier, but a veneer ...
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 ...
At this time the glacier covering the area had grown thin, so it was restrained by dolomite rock layers in the Lake Michigan basin. Where the glacier stopped, glacial till and sand was deposited, creating the hills of the moraine. After the Valparaiso Moraine was formed, the glacier retreated and formed the Tinley Moraine.

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.
