 and Ohio, and northwest across Ohio (see image of former course and tributaries). Massive continental ice sheets began to cover large parts of Ohio and other states downstream (west) of Ohio between 2.5 and 3 million years ago. Their presence caused lakes to form along the Teays and associated rivers. Overflow of these lakes into nearby, lower valley caused large floods and new rivers to form. These rivers include the Ohio and Scioto

 rivers, which are associated with the most direct evidence of the Teays River.

Visual remains of the Teays River include large valleys containing only small streams (such as the mile-wide valley from Huntington to St. Albans and the valley beginning from Wheelersburg, Ohio north). The valleys can be seen on aerial and satellite images. However, short segments of the valleys are occupied by the Ohio and Scioto rivers. The Scioto River flows through the valley in the opposite direction (south) taken by the Teays River (north).
Through all its shifts and changes the river has retained a continuous history, with the result that the present Ohio-Mississippi river system contains some unique relict
