Lost Ancient Technology of Peru & Bolivia
Ancient Peru and Bolivia, like Egypt, contain enigmas and mysteries, especially in stone which most conventional scholarship can`t explain. Rather than simply being exclusively the works of cultures such as the Inca, there are many megalithic wonders which defy both the conventional time lines and known levels of technology attributed to the ancient people of South America. The most glaring example is most likely Puma Punku, near the shore of Lake Titicaca in Bolivia, which hints at not only being several thousand years old, but also seems to have been achieved using what we would call high level machine technology.
There are also many sites in Peru, and especially near the city of Cusco that also show the hall marks of having been made by cultures using technology supposedly not known by cultures such as the Inca. A massive collection of photographic and detailed analysis is contained in this book, as well as on site observations by leading engineers.
