Scattered erratics in northeastern Kentucky and southern Ohio are pre-Kansan in age. Only the Nebraskan is recognized as earlier than Kansan; these have been designated as remnants of deposits left by the Nebraskan glacier. The ice sheet overrode the preglacial Teays creating ponds or glacial lakes. The back up of water diverted the upper basin over the surrounding divides into the preglacial Ohio River. Thus the ‘deep stage’ more likely is post-Nebraskan and pre-Kansan in age rather than preglacial. With the withdrawal of the Nebraskan glacier, which caused integration of the upper Kanawha (Teays) with the preglacial Ohio, a vastly shortened, unnamed descendant of the Teays apparently headed somewhere in west-central Ohio and cut the ‘deep stage’ across Ohio, Indiana, and Illinois during the long Aftonian interglacial stage, which followed.
