Cumberland Gap history, Appalachian Mountains caves, karst landscape geology, There is a moment, just before the sun rises over the Cumberland Gap, when the world seems to hold its breath. But what lies beneath this famous mountain pass? Tonight on History Sleepy Time, we venture beneath the gentle ridges of the Appalachian Mountains to explore a hidden world forged over 400 million years. While historical figures like Dr. Thomas Walker and Daniel Boone famously carved the Wilderness Road above, a silent, unmapped universe of underground rivers, vast limestone caverns, and blind cave creatures was quietly thriving below. Join us on a peaceful, atmospheric journey as we explore the deep geological time of the Cumberland Overthrust, the rich Indigenous history of the region, and the mysterious karst landscape that scientists are still struggling to map today.
