Southern Ohio, northern Kentucky, and western West Virginia are a unique corner of Appalachia. While the modern Ohio River is a key part of this region's identity, two huge, ancient river valleys that appear to lead nowhere still scar the southern Ohio landscape, with similar valleys visible in West Virginia.
