Whilst Tiwanaku and Pumapunku are clearly the work of an extremely advanced civilization, some people believe they are also more than 17,000 years old, throwing a spanner firlmy in the works of the Orthodox historians.
The processes and technologies involved in the creation of these temples are still not fully understood by modern scholars. The architectural achievements seen at Pumapunku are striking in light of the presumed level of technological capability available during its construction. Due to the monumental proportions of the stones, the method by which they were transported to Pumapunku has been a topic of interest since the temple’s discovery.
The largest of these stone blocks is 7.81 meters long, 5.17 meters wide, averages 1.07 meters thick, and is estimated to weigh about 131 metric tons (about the weight of 60 cars). The second largest stone block found within the Pumapunka is 7.90 meters long, 2.50 meters wide, and averages 1.86 meters thick. Its weight has been estimated to be 85.21 metric tons. Both of these stone blocks are part of the Plataforma Lítica and composed of red sandstone. Based upon detailed petrographic and chemical analyses of samples from both individual stones and known quarry sites, archaeologists concluded that these and other red sandstone blocks were transported up a steep incline from a quarry near Lake Titicaca roughly 10 km away.
In assembling the walls of Pumapunku, each stone was finely cut to interlock with the surrounding stones and the blocks fit together like a puzzle, forming load-bearing joints without the use of mortar.
The precision with which these angles have been utilized to create flush joints is indicative of a highly sophisticated knowledge of stone-cutting and a thorough understanding of descriptive geometry. Many of the joints are so precise that not even a razor blade will fit between the stones. Much of the masonry is characterized by accurately cut rectilinear blocks of such uniformity that they could be interchanged for one another while maintaining a level surface and even joints.
The blocks were so precisely cut as to suggest the possibility of prefabrication and mass production, technologies far in advance of the Tiwanaku’s Incan successors hundreds of years later.
Puma Punku is believed to have once contained a great wharf, and a massive four part structure. Yet all that remains today are megalithic ruins from some cataclysmic event in history. A great earthquake? A comet that came too close to the Earth? A worldwide flood? These are all possible causes to the destruction of the once great structure that is now the ruins of Puma Punku.
Not only is there evidence to support the claim of a cataclysmic flood, but there is even evidence to support the theory that people once lived there before such a flood even occurred. The suspected flood could have happened somewhere around 12,000 years ago, and there is scientific evidence of tools, bones, and other material within flood alluvia, which suggests that a civilized people were there prior to any flood.
Local legend holds that the site was created by giants, who later angered the gods and so were swept away in a flood, but the large stones have encouraged some alternate creation theories in recent years.
