West Virginia's Ancient River Shadows Haunt Its Mountains

The ancient Teays River, once a major river system in West Virginia, was buried under sediment by the Laurentide Ice Sheet during the last Ice Age. This glaciation reshaped the region's geography, creating large lakes like Lake Tight and Lake Monongahela, which altered river courses and led to the formation of the Ohio River. Geologists continue to study these changes, piecing together the complex history of the region's prehistoric rivers and glacial impacts.
