Hidden in the hills of Eastern Oklahoma lies one of America’s greatest ancient mysteries—the Spiro Mounds Archaeological Center.
Between 800 and 1450 AD, this site was the bustling center of a powerful Mississippian civilization that built massive earthworks, sacred chambers, and underground tombs filled with incredible treasures. Though heavily looted in the 1930s and scattered across the globe, legends say sealed chambers still remain, holding secrets that could rewrite history.
Who were the people of Spiro? Where did their advanced knowledge come from? And why did their great city collapse? Join us on The Only in OK Show as we venture just off Highway 9 to uncover the remains of a thriving, thousand-year-old culture hidden beneath American soil!
