Puma Punku is a temple complex created by the Tiwanaku culture located at an elevation of twelve thousand nine hundred feet above the sea in Bolivia. It is one of three settlemets attributed to the Tiwanaku culture. At the site we find huge megalithic stones some weighing up to 440 tons (600 full sized cars). The quarry from where these stones were carried from lies 10 miles from the site. Modern Archeologists propose the same explanation here as they do for all the other megalithic buildings of antiquity, that the stones were transported by rolling them on wooden logs. What they neglect to take into account is that Puma Punku lies in a broad, unprotected, arid plain that hosts no trees as its elevation places it above the natural tree line. The Tiwanaku culture are believed to be a precursor to the Inca empire. However little is known about them since they had no known written language. What remains of this culture are astonishing stone monuments that bear close resemblance to those created by other ancient cultures all over the planet.
The architectural feats found at Puma Punku reveal a precise level of planning which is unheard of from a culture with no written language. Some of the stones at Tiwanaku have puzzled scientists for years as their perfect angles, drill holes and smooth surfaces that bear evidence of some type of ancient machinery. Many researchers have dated Puma Punku to a time in history that predates the dawn of civilization by thousand of years. Arthur Posnansky, a German – Bolivian scholar studied the site for nearly 50 years. He determined by analyzing astronomical alignments of the ruins that obliquity of the ecliptic at the time of the building of the Kalasasaya was 23 degrees, 8 minutes, and 48 seconds. Based on these calculations, Posnansky was thereby able to date the initial construction of the Kalasasaya and Tiahuanaco to 15,000 BC. This date was later confirmed by a team of four leading astronomers from various prestigious universities in Germany. However this answer is considered controversial, even impossible, so it has been ignored and censured by the scientific community for fifty years now.
Here we can appreciate the precision of some of the grooves made on the granite stones. (Granite being among the hardest minerals on earth) Inside the groove there are very small drill holes which are equally spaced. The tools needed to make these complex marks are far beyond the ones available to people of the time. Not to mention that no tools have ever been found at the site.
The image on the left is of a granite stone fitted with metal clamps, many rocks were fitted this way at the site. Interestingly, similar clamp designs can be found in ancient site around the world. The image to the right contains examples from TL Dendera Egypt, TR Angkor Wat Cambodia, BL Tiahuanaco, BR Ollantaytambo, Peru.
