Explorer David Hatcher Childress discusses mysterious ruins found in the mountains of Peru and Bolivia in his search of ancient technology and the secrets of megalith building. He examines the amazing stonecutting at Puma Punku, a site neighboring the ancient ruins of Tiwanaku near Lake Titicaca in Bolivia. He looks at whether the so-called Inca wallsfound in Cuzco and at other sites such as Sacsayhuaman, Ollantaytambo and Machu Picchuwere really made by the Incas. The evidence seems to support the idea that they were actually constructed by a far older culture.
