They tell us the Cheyenne Mountain Complex was carved into solid granite in just six years during the 1960s — but the evidence tells a different story. A fully self-sustaining underground city, complete with 25-ton blast doors, independent air, water, and power supplies, and no public access to its underground structures even today. Were these massive complexes in Colorado and Russia truly built — or found? In this episode, we uncover why military designation legally locks these ancient sites away, why the public is never shown proof, and why these vast underground worlds might belong to a civilization far older than we are allowed to believe.
