About Mark:

Mark Eddy is a historian, researcher, and author whose work explores the forgotten prehistoric legacy of the Ohio River Valley and the scholars who first uncovered it. A native of the region, Eddy has spent decades studying the intersection of geology, anthropology, and early American antiquarian research, bringing long-overlooked discoveries back into the historical conversation. He is also well known as the host of Mark Eddy’s popular podcast interviews, where he connects with experts, researchers, and explorers who share his passion for America’s ancient past, unexplained history, and lesser-told narratives. In Lakes, Lizards, Linton and Leverett, Eddy combines historical documentation, scientific analysis, and field experience to shine new light on the Permian fossils, earthworks, and cultural mysteries that shaped the Upper Ohio Valley—revealing a region far richer and older than most realize.
