This video segment, adapted from Where the River Bends, a KET documentary, shows how climate change and glacier movement during the Ice Ages caused the now-vanished Teays River to move to the south and become the Deep Stage Ohio River. Listen to a local historian describe how the advance and retreat of the Wisconsin Glacier about 100,000 years ago caused the path of the Deep Stage Ohio River to change, creating the course of the modern Ohio River that impacted the growth and development of the region.
