The Enigma Of Puma Punku in Bolivia

Clearly one of the strangest and most misunderstood ancient sites in the world is that of Puma Punku, located at 13,000 feet in altitude and about 2 hours from Bolivia's capitol city La Paz.


Thought by conventional academics to have been created by the Tiwanaku culture between 100 and 900 AD, these scholars can not explain how the hard grey andesite stone was shaped with such amazing precision (some of the surfaces are within 2/10,000 of an inch of being laser flat.) Also, the quarry from which these sometimes megaton blocks were removed is more than 70 km away.

Moreover, there is no other site in Bolivia, and indeed the Americas where the same techniques of stone shaping can be found. It seems as if the master builders appeared, built Puma Punku and then left, never to be heard from again...


From about 1000 AD until the latter part of the 19th century Puma Punku was used as a quarry by successive cultures. What still remains at the site is a treasure for all of humanity. 


Even the famous Sun Gate of Tiwanaku may have originally been part of Puma Punku. Come with us on our September or October tours, 2014 and experience this enigma for yourself:

Greetings. This is the beginning of a blog, which I hope to add to every day where possible. As some of you may know, aside from the tours that I do and books that I write as well as videos I make, I am involved in research projects. Two which are underway at present are: 1/ Testing of the elongated skulls of Peru: samples are being processed at present by a Peruvian archaeologist to be sent to a genetics lab in the United States in order to begin trying t... continue reading

A Tale Of Two Lost Cities: Machu Picchu and Choquequirao

Machu Picchu, the lost city of the Inca, or at least that is how this citadel high in the Amazon borderlands is advertised to the world at large. Indeed, the Spanish conquistadors failed to find this masterpiece of ancient complex construction during their campaign of cultural exploitation and degradation beginning with their arrival on the shore of what was to become called Peru in 1532. This famous site caught the imagination of the world when National G... continue reading

Elongated Skulls Of Paracas: A People And Their World

Four hours drive south of Lima Peru lies the Paracas Peninsula, part of which is an ecological reserve, where one can see wildlife such as sea lions, and a myriad of various sea bird species. The area is amazingly rich in seafood, and abundant fresh water exists just below the surface of the desert sands. Therefore, it would seem to be a perfect place for people to live. Stone tools, of various forms and styles of shaping have been found in the area, and c... continue reading

Ollantaytambo: House of the Dawn; an Underestimated Inca Monument

The vast majority of visitor trips to Peru go something like this; land in Lima, the capital, tour around the city for a day, and then fly to Cusco. Once there, while adjusting to the 12,000 foot plus altitude, a walk through the historic city center is a must, and then, the next day, take in Sachsayhuaman, the “fortress” of the Inca perched on a hill overlooking the city. But the main attraction still awaits; a fabled “lost city” abandoned by the Inca in ... continue reading

The Disappearance Of The Children Of Viracocha, Part 3: Cuzco: The City Which The Inca Found, Not Founded

The greatest mystery about the Inca is not their accomplishments, but their origins. Where could such a sophisticated culture have come from? It is well written through accounts of the conquistadors, and Inca descendants that these people came to Cuzco as a fully developed society; teaching agriculture, metallurgy, animal husbandry, textile weaving, and the arts of warfare and politics, amongst other civilizing pursuits, to seemingly less developed people... continue reading

The Disappearance Of The Children Of Viracocha, Part 2: Inca Epilogue, Chachapoyas, Rapanui, Aotearoa And Hawaii

In part 1 I wrote about the Inca and how they were regarded as the descendants of the Viracochas, a people of mythic proportions seemingly lost in time and often thought of as being fictitious. Part of the reasoning behind this is the fact that much if not most of Inca history, which was mainly oral in nature, was crushed once the Spanish conquered Cuzco; the administrative, military and spiritual center of the Inca in 1533. What they did have as a “writte... continue reading

The Disappearance Of The Children Of Viracocha

Something that has perplexed most if not all researchers of Peruvian history is the creator deity named Viracocha. Deemed to have been the ancestor of the Inca, it was he who created the first Sapa (high) Inca, Manco capac, as well as his full blood sister (and wife) Mama ocllo from the waters of Lake Titicaca, and told them to move from that place and create a new civilization. One thing that is often overlooked is that Viracocha and Viracochan are two c... continue reading

A Brief History Of The Incas; From Rise, Through Reign, To Ruin

I have always been fascinated by Indigenous cultures. As a child growing up on the west coast of Canada, I developed a keen interest in native Haida and Kwagiulth art and oral traditions, when my grade 4 teacher read native “mythsEto my classmates and me. What struck me, even at that early age, was the way that the indigenous story writers treated all of creation, whether animal, plant or human in form, as being equal; there was no social hierarchy as co... continue reading
