This river may predate the break-up of western Gondwana as an extension of a proto-Congo river system, 200 Mya during the Jurassic. Ohio: 3~2.5 Mississippi River: Formed when the Laurentide Ice Sheet dammed the north flowing Teays River during the Pre-Illinoian glaciation. The drainage area of the Teays could no longer drain to the north, and ...
The Teays River / ˈ t eɪ z / [1] (pronounced taze) was a major preglacial river that drained much of the present Ohio River watershed, but took a more northerly downstream course. Traces of the Teays across northern Ohio and Indiana are represented by a network of river valleys.

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.
The ancient lake was similar in size to the current lake during glacial retreat, but for some period the eastern half of the lake was covered with ice. Early-period Lake Erie was made up of smaller lakes (Lakes Warren, Wayne, Maumee and Lundy) with lower depths. Much of the ancient lake bed is now northern Ohio.
