The Ancient Ghost Cities of America: Why Did They Vanish?

Deep in the American Southwest sit perfectly preserved, 5-story stone skyscrapers built into the sides of sheer cliffs. Yet, 700 years ago, the advanced civilization that built them vanished without a trace. Welcome to History’s Blindspot. Long before European contact, the Ancestral Puebloans ruled the brutal deserts of North America. They engineered sprawling road networks, mapped the cosmos without telescopes, and built Chaco Canyon—the "Manhattan of the ancient world." But around 1150 AD, they abruptly abandoned their open-air cities and began building claustrophobic, heavily defended fortresses high up in the cliffs of Mesa Verde. In this documentary, we investigate the terrifying 50-year mega-drought that triggered their collapse, the violent internal conflict that followed, and the incredible true story of where they actually went. Why do you build an impenetrable fortress in the sky, only to abandon it overnight? 🔔 Subscribe to History's Blindspot for more forgotten history 👇 Join the Conversation: If you had to abandon your city tomorrow and could only carry what fit in a backpack, what is the one thing you would take?
