Tihuanaco was once a thriving lakeside port until a catastrophic event destroyed it around ten thousand years ago. At that time, Lake Titicaca was much larger than it is today, with waters reaching depths of over a hundred feet. Archaeologist Professor Bosnanski has uncovered remnants that prove Tihuanaco was a bustling port as early as 15,000 years ago. However, a massive flood triggered by an earthquake obliterated the city. Archaeologists have discovered human and animal remains, as well as broken pottery, jewelry, and tools within the sediment layers. This reveals a long-buried history, shedding light on the secrets of humanity, nature, and societal change.
