In this episode of America Unearthed, host and forensic geologist Scott Wolter takes a look at mysterious stone walls, in the East Bay area, near San Francisco. This episode bounces east, and makes a strong case that the Chinese of the Ming Dynasty made it to America in the early 1400's. It's also possible that earlier Chinese expeditions, perhaps carrying explorer Marco Polo, made it to North America, as well.
I've been fascinated by archeology, the explained, and the unexplained artifacts, in the world since I was a kid. The mysterious, 50 mile long stone walls in the Bay Area are another interesting historical anomaly. In a little side note, the searcher on Oak Island, in Nova Scotia, Canada, found a Chinese coin this past summer (2020), featured in the current season of the show, The Curse of Oak Island. The coin dates from 200 B.C.E. to about 900 A.D. Personally, I think humans traveled a lot farther in ancient, and even pre-historical times, than we give them credit for. I think there are whole chapters of human history, yet to be revealed.
