Forensic geologist Scott Wolter investigates a massive, 50-mile stone wall in California that has no official place in American history books. By tracing the construction style back to ancient China and analyzing rare Ming Dynasty maps, Wolter uncovers evidence of a massive seafaring operation that reached the US West Coast centuries before Columbus. Was Marco Polo a secret agent on these voyages? From the foothills of San Francisco to the Great Wall itself, we explore the artifacts and evidence that could rewrite the history of the New World forever.
