Two Mysteries in Siberia: A Possible Ancient Connection

Por-Bajin is a remote archaeological site located in the mountains of southern Siberia. The walls of the site, which resemble a fortress, are massive – up to 10 meters tall and 12 meters thick at the base – enclosing an area of about seven acres containing the remains of dozens of buildings. Constructed from clay supported by wooden beams, the buildings within the site are thought to have been built around 780 CE by a nomadic people known as the Uighurs.

What is particularly unusual about the site is that it is located on an island in the middle of a shallow lake almost literally in the middle of nowhere. If it were a fort, a shallow lake would offer little protection. Adding to the mystery is a lack of artifacts and evidence of sustained occupation. Perhaps this should come as no surprise as the ground beneath the buildings is permafrost and the buildings had no apparent heating system. Archeologists admit that after two years of intensive fieldwork, with one-third of the site excavated, Por-Bajin remains a mystery.

Although the site is said to be oriented east-west, Por-Bajin is, in fact, rotated 7.5 degrees east of north. Can its orientation offer any clues about when it was built, and by whom?

Chinese Influence

In China, there are numerous earthen pyramids that were constructed as mausoleums and burial mounds containing the remains of early emperors and their families. Some of these pyramids are oriented to the cardinal directions, but some are not. Historically, the art of placing, arranging, and orienting cities, streets, palaces, houses, and tombs, known as divination, geomancy, or Feng shui, has been an important element in Chinese landscape design and city planning.

Researchers from the Czech Republic have shown that there is a correlation between the orientation of many Chinese pyramids and the location of the magnetic pole at the time they were built. The magnetic pole wanders slowly over time. By using a model of the past motion of the magnetic pole and knowing the approximate construction date of the site, the Czech study shows that some form of magnetic compass, which was known to the Chinese as early as the fourth century BCE, could have been used to align the pyramids to magnetic north.

Archaeologists have noticed that the architecture and construction methods at Por-Bajin are similar to those in China at the time. Did the builders of Por-Bajin use a compass to align the site to magnetic north? At the time of construction in 780 CE, the north magnetic pole was located near 83°N 40°E (Figure 2). A compass reading at Por-Bajin would have pointed 10° west of north, about 17.5° west of the site’s alignment to north. It is thus highly unlikely that a compass was used to align the site since it would have pointed in the wrong direction.

Figure 2 Location of the north magnetic pole at 780 CE is located at 83°N 40°E (orange circle). The magnetic declination at Por-Bajin would have been approximately 10° west of north (from McElhinny and McFadden ).

Past Celestial Alignment

Does the azimuth angle of the site, 97.5°, coincide with solar or lunar events such as solstices or lunar standstills? Table 1 lists sunrise azimuths at the summer and winter solstices and moonrise azimuths at the major and minor lunar standstills at Earth’s minimum and maximum obliquity angles. Clearly, the site is not rotated enough to the east to line up to any of these events.

Was Por-Bajin aligned to a previous location of the North Pole? The Hudson Bay, Greenland, Norway Sea, and Bering Sea poles are located at azimuth angles −2.4°, −4.4°, −28.2°, and 47.9°, respectively. Again, the answer is no.

There is one last possibility – that Por-Bajin could have been aligned to solar or lunar events referenced to earlier positions of the pole.

Table 1 Minimum and maximum obliquity values of sunrise and moonrise azimuth angles at solstices and lunar standstills.
Figure 3 East-west axis of Por-Bajin could have aligned with the winter-solstice sunrise when the North Pole was in the Norway Sea and Earth’s obliquity was near its maximum value (top yellow line in inset).

Figure 3 compares the alignment angle of the site to summer and winter solstices and major and minor lunar standstills in summer and winter at minimum and maximum obliquity angles for the current pole (white), Hudson Bay pole (magenta), Greenland pole (green), Norway Sea pole (yellow), and Bering Sea pole (red). For an alignment to have been possible it must lie between the minimum and maximum obliquity values. Comparing the orientation of Por-Bajin to these alignments we find that it would have lined up with the winter solstice sunrise if the pole were located in the Norway Sea.

The Norway pole is −28.2° or 28.2° west of the current North Pole. The site would have been aligned at an azimuth angle of 28.2° + 97.5° = 125.7°, which is within 0.3° of the winter sunrise/summer sunset solstice angle of 126° at the latitude of the site when the pole was in the Norway Sea and Earth was at maximum obliquity (Figure 4).

Figure 4 Alignment of Por-Bajin to the solstice when the pole was in the Norway Sea

Notice that the diagonal of the site is aligned due east-west. This means that the solstice angle relative to east, 126° −90° = 36°, is also encoded in the aspect ratio of the site’s bounding rectangle; i.e., W/L = tan 36°.

As shown in Figure 3 Por-Bajin would have aligned to the solstice when Earth’s obliquity was close to its maximum value of 24.2°, which occurred 9,000 years ago and reoccurs every 41,000 years. Using a modified version of Charles Hapgood’s original pole shift timeline places the North Pole in the Norway Sea 75,000 to 125,000 years ago. During this period of time, the site would have lined up to the solstice 9,000 + 2 x 41,0000 = 91,000 years ago.

Figure 5 Aspect ratio of Por-Bajin is related to its orientation (see text).

What is particularly intriguing about this date is that at this time, near the end of the Sangamon interglacial period, this part of the world would have been warmer, making the existence of Por-Bajin here in central Siberia much more plausible than it is today.  The only problem with this dating is that according to accepted genetic timelines modern humans had not yet left Africa.

A Denisovan Connection?

Evidence of Denisovans – a long extinct humanoid species who coexisted with the Neanderthals about a half-million years ago – was first discovered in a cave located about 900 km west of Por-Bajin. Archaeologists there have mapped out 22 layers of sediment. The earliest evidence of occupation is in the deepest layer (1) going back 282,000 years. In 2008 a stone bracelet was found in layer 11 that has been dated to about 70,000 years ago. The bracelet shows evidence of manufacturing technology typical of much later periods, including a hole made with what appears to have been a high-speed drill.

Given the apparent fine-scale technological sophistication of the Denisovans 70,000 years ago, and evidence suggesting that they inhabited this part of the world on and off for 200,000 years or more, could they have built larger structures during this period of time? Pushing the limits of what we know, given the Denisovans possessed an appreciation for jewelry and art perhaps they lived in other places besides caves.

Earlier we wondered how and why a nomadic people built an enormous site on an island in the middle of a lake in such a harsh climate. Perhaps they did not. Could places like Por-Bajin have been first established by Denisovans that were co-opted by later civilizations, the last being the Uighurs? Perhaps deeper excavations at Por-Bajin and other nearby archaeological sites might reveal the true origin of these sites.

Finally, one has to wonder if the Russian government’s interest in Por-Bajin, including its support of the excavation with paramilitary troops starting 2007, had anything to do with the discoveries being made in the nearby Denisova Cave at around the same time. Do they suspect, or have they already discovered a Denisovan connection between these two sites?

Finding evidence of Denisovans at Por-Bajin would support the hypothesis proposed in Before Atlantis that the site was not built by modern humans in historical times but by an earlier indigenous technological civilization in the distant past.

Evidence of Great Antiquity at Machu Picchu

Before Atlantis introduces the idea that many ancient sites throughout the world might be far older than previously thought based on the alignment of these sites to previous locations of the North Pole. This article discusses one of the sites, Machu Picchu, in greater detail.


Unlike so many other places that were destroyed by the Spanish, Machu Picchu remained unknown to the outside world until its rediscovery by Hiram Bingham in 1911. Most archaeologists believe Machu Picchu was built by the Incas for their emperor Pachacuti in the fifteenth century; however, no one has been able to adequately explain all of the structures at the site in terms of technology that is thought to have been available to the Incas at that time.

Figure 1 Machu Picchu divided up into four sectors (from Magli).

For the purpose of understanding the layout and orientation of the site, Giulio Magli divides Machu Picchu into four sectors (Figure 1). Sectors I and II occupy the southeast and northeast portions of the site consisting of numerous compounds called kanchas.  The kanchas at Machu Picchu contain structures constructed from coarsely fitted stones that conform to the terrain and are oriented in generally eastern facing directions. Magli sites evidence that the Incas could have conducted accurate celestial observations related to the solstices within these two sectors.

Skipping Sector III for the moment, Sector IV contains the enigmatic Temple of the Three Windows and the Intihuatana. In contrast with the kanchas, the structures in Sector IV consist of much more massive and precisely cut and fitted stones. Archaeologists believe that the structures in Sector IV were constructed last and left unfinished by the Incas. Another possibility is that the structures in this part of the site are the ruins of something that is much older, constructed by an earlier pre-Inca civilization. Is there any evidence of an earlier civilization at Machu Picchu?

Temple of the Three Windows

Sector III is an open northwest facing area that Magli associates with a range of directions between 135° to 155° (or -55° to -25°) that are thought to have been important to the Incas. Too far south of east to be aligned to the Sun or Moon, Magli suggests that this range of orientations might reference certain celestial features such as the Milky Way – the celestial counterpart of the Vilcanota river, which could have been used to determine the timing of the equinox based on its relation to the Sun. This direction also turns out to point to a possible pole in the Bering Sea 80,000 to 85,000 years ago or more. Could this direction have been important to the Incas simply because it was once north?

That this direction once pointed north seems consistent with the alignment of the Temple of the Three Windows (Figure 2). The orientation of the eastern wall, -34° (or 34° west of north) is aligned to within a few degrees of the Bering Sea pole. This means that if the North Pole were in the Bering Sea, the three windows would have faced due east and the Sun would have risen in line with the temple on the equinox (Figure 3).

It has been suggested that the Intihuatana (Figure 4) or “hitching post of the Sun,” a name attributed to Bingham, was designed to mark dates when the Sun would be directly above the Intihuatana and so would cast no shadow. A simple gnomon with a vertical shaft casts no shadow at noon on the equinox only if it is at the equator (Figure 5) Since Machu Picchu is about 13° south of the equator the device must be tilted in the direction of the Sun for it to disappear on a given date (Figure 6). For example, if it is intended to mark the date of the summer solstice, it must be tilted in the direction of the sun on that date by approximately 11°; if it is intended to mark the date of the equinox, it must be tilted due east by approximately 13°.

Figure 5 Solar path at the equator. The middle line is the path on the equinox.
Figure 6 Solar path at Machu Picchu. The southern path is that of the sun on the summer solstice.

If the function of the Intihuatana is just to mark the days when the shadow of the sun disappears why is its shape so complex?

Figure 7 3D model of the Intihuatana with alignments to the Bering Sea pole (solid line) and to the solstice directions (dotted lines).

Before the Bering Sea to Norway Sea pole shift, Machu Picchu would have been rotated approximately 34° counterclockwise (i.e., west of north) relative to its current orientation and shifted about 6° further south in latitude. Figure 7 is a 3D model of the Intrihuatana with alignments relative to the Bering Sea pole. Being even further south than it is now, the surface would have to have been tilted even further toward the east for the Sun to disappear on the equinox. Although some sides and edges of the Intihuatana stone appear to be somewhat aligned to the pole and the winter solstice sunrise directions, its shape seems inconsistent with that of a device designed to mark either solstices or the equinox at this time.

Figure 8 3D model of the Intihuatana with alignments relative to the Norway Sea pole (yellow lines) and possible sides and edges corresponding to these directions.

After the pole shift, the Temple of the Three Windows would no longer face east. A new way might have been required to mark the cardinal or other important directions at Machu Picchu.  It is hypothesized that several versions of the Intihuatana were constructed over time. The original device could have been constructed after the Bering Sea to Norway Sea pole shift (Figure 8) at which time the gnomon and several sides appear to closely reference the directions of the pole and the summer solstice. Was the original Intihuatana created at the time when the North Pole was in the Norway Sea to mark the summer solstice?

Figure 9 3D model of the Intihuatana with alignments relative to the Greenland pole (green lines) and possible sides and edges corresponding to these and previous directions.

A later pole shift from the Norway Sea to Greenland would rotate Machu Picchu to within a few degrees of its current orientation and shift its position to within 2° of the equator (Figure 9). At this point, the original device was no longer aligned to the summer solstice, but with a vertically oriented gnomon would have been virtually shadowless at noon on the equinox. Perhaps it is at this point in time that the device serendipitously became the “hitching post” of the Sun.

Figure 10 3D model of the Intihuatana with alignments relative to the Hudson Bay pole (violet lines) and possible sides and edges corresponding to these and previous directions.

After the next pole shift from Greenland to Hudson Bay, Machu Picchu shifted south several degrees and rotated clockwise several degrees. It is possible that the Intihuatana could have been modified to once again be an equinoctial marker by adjusting its inclination slightly to account for its new latitude and alignment to north.

Figure 11 summarizes possible alterations to the shape of the Intihuatana stone based on its past alignment to ancient poles and corresponding solar directions. Could the complex and otherwise inexplicable shape of the Intihuatana be the result of numerous incremental changes that had to be made to the device, originally designed as a solsticial marker, for it to continue to function later as an equinoctial marker?

Application of Charles Hapgood’s hypothesis that the Earth poles have shifted several times over the past 100,000 years provides new insights into many ancient sites that have defied conventional explanation. Our analysis suggests that the Temple of the Three Windows might be one of the oldest structures at Machu Picchu, and that the Intihuatana, constructed sometime later could have functioned first as a solsticial marker and later as an equinoctial marker over most, if not all, of its long history.

Hapgood’s Pole Shift Hypothesis Revisited

In Before Atlantis I apply Charles Hapgood’s hypothesis that Earth’s poles have shifted several times over the past 100,000 years to understand the alignment of numerous ancient sites across the world and to use the hypothetical alignment of the these sites to ancient poles as a new means of dating the sites. This article presents a revised version of Hapgood’s original pole shift hypothesis.

Milankovitch Cycles

It is widely accepted in the scientific community that climate patterns are driven to a large extent by the amount of solar radiation that reaches the Earth. The amount of radiation depends on a combination of factors including changes in the eccentricity in our orbit around the sun, axial tilt or obliquity, axial and apsidal precession, and orbital inclination. The combination of these effects gives rise to what are called Milankovitch cycles.

Although there is extensive evidence that the variation in solar radiation is an important factor, there are certain problems with Milankovitch’s model related to the timing of the cycles and their correlation with climate events. Perhaps the biggest problem is that the magnitude of climate changes have turned out to be far greater than what is predicted by the model.

Pole Shifts

The idea of pole shifts originates in a talk given in May 1872 by the French ethnographer Charles-Étienne Brasseur de Bourbourg called “Chronologie historique des Mexicains.” He interpreted passages in the lost Codex Chimalpopoca that beginning about 10,500 BCE, four periods of cataclysms had changed the world, each caused by a temporary shifting of Earth’s axis [1]. In the mid 1900s Hugh Auchincloss Brown [2] and Charles Hapgood [3] proposed that shifts of the geographic pole could explain ice ages, mass extinctions, and other worldwide events. Hapgood proposed that an asymmetrical accumulation of polar ice created a force that caused the crust of the Earth to displace, i.e., slide over, the mantle. Albert Einstein later determined that this force was insufficient, leaving Hapgood’s hypothesis without a physical cause.

In the 1990s, a team led by Joseph Kirschvink found paleomagnetic evidence of a massive 90° pole shift 500 million years ago at around the time of the Cambrian explosion [4]. Although there is some indication that the magnetic pole has deviated significantly from the geographic pole over the past 100,000 years, paleomagnetic evidence of a shift in the geographic pole over this period is inconclusive. Perhaps the best independent evidence supporting Hapgood’s pole shift hypothesis is the alignment of over four dozen sites to four previous locations of the North Pole as described in Before Atlantis.

Adjusted Timeline

Rather than interpreting the ice ages as global climate events, Hapgood believed the spatial patterns of climate change were best explained by changes in the geographic location of the North Pole. By examining patterns of climate change, he estimated that three pole shifts had taken place during the past 100,000 years: 1) from Hudson Bay (60˚N 73˚W) to the current pole, 12,000 to 17,000 years ago, 2) from the Atlantic Ocean between Iceland and Norway (72˚N 10˚E) to Hudson Bay, 50,000 to 55,000 years ago, and 3) from the Yukon (63˚N 135˚W) to between Iceland and Norway 75,000 to 80,000 years ago (Figure 1).

Figure 1 Hapgood’s original timeline relating climate change to pole shifts.

Figure 2 shows an adjusted timeline based on currently accepted periods of glacial and interglacial events in Europe and North America. Before 125,000 years ago, during the Illinoian glaciation, we propose that the North Pole was in the Bering Sea north of the Aleutian Islands. At the start of the Sangamon interglacial period it shifted to a location in the Norway Sea. During this period the climate in North America became warmer and Europe became colder. Sometime between 75,000 to 125,000 years ago the pole shifted towards Greenland. About 75,000 years ago the pole moved to a location in Hudson Bay at which time the climate in North America became colder. Finally 12,000-17,000 years ago after the pole shifts to its present location, both North America and Europe become warmer.

Figure 2 Revised timeline based on more recent glacial data

Figure 3 shows our refined pole location model and adjusted timeline. In Before Atlantis it is argued that the pole spent more time in the Norway Sea than it did in Greenland based on a greater number of sites discovered to be aligned to the Greenland pole. As this interpretation may not be correct, the order and timing of these two pole shifts remains an open question.

Earth Ancients Radio

On October 27 I spent about an hour talking with Cliff Dunning on his show, “Earth Ancients” about Before AtlantisClick here to get the podcast, which is available on iTunes.

Martian Revelation Radio Show

This past Saturday, October 12, I rolled out my new book Before Atlantis on the “Martian Revelation” radio show hosted by Gary Leggiere. I spoke with Gary about the book, my past involvement in the independent Mars investigation and what I have been working on more recently. I related the idea of pole shifts on Mars to those on Earth and explained the concept of using geometrical alignments of archaeological sites to previous positions of the North Pole to date the sites using Charles Hapgood’s theory of crustal displacement.

An alternative hypothesis

The popularity of alternative archaeology has grown in recent years due to the inability of conventional theories to explain unexpected discoveries within existing scientific paradigms. When Erich von Däniken published Chariots of the Gods? in 1968, the gap between mainstream archaeological thought and the existence of unexplained structures throughout the world was so great that the “ancient astronaut” theory seemed like the only possible explanation. In a similar way, Zecharia Sitchin’s interpretation of ancient Sumerian myths as prehistoric contacts with extraterrestrials was the only way to make sense of those myths.

The age and distribution of the sites that I discovered suggested another possibility: that the original structures at these sites might have been built by a previous, highly developed technological civilization that existed throughout the world tens of thousands of years ago or more. Instead of an exogenous (i.e., extraterrestrial) influence, perhaps an indigenous technological civilization evolved over the timeline of an earlier human migration out of Africa 200,000 to 300,000 years ago, much like we have during the last 70,000 years. If so, our ancestor’s past encounters with this older civilization could have been the source of ancient myths of powerful gods, lost continents, even Atlantis.

An unexpected discovery

Quite unexpectedly, I made an interesting discovery this past year. While using Google Earth to view several archaeological sites in Mexico that I hoped to visit during an upcoming trip, I noticed that most of the structures were not aligned to the cardinal directions – north, south, east, and west. This seemed strange, as most sites, even ancient ones such as the pyramids in Giza, are aligned, often with uncanny precision, to the North Pole.

In the 1950s, a college professor by the name of Charles Hapgood developed a theory to explain patterns of climate change as a result of shifts in the geographic position of the North Pole. Back in the days of my Mars research I remember learning about a site in Mexico that was thought to have once faced a previous location of the pole in Canada, just east of Hudson Bay, at least 15,000 years ago.

Hapgood hypothesized two other prior locations of the North Pole: one in Greenland 50,000 years ago and the other in Alaska around 80,000 years ago. I discovered that, with some relatively minor adjustments to Hapgood’s pole locations, the sites in Mexico, as well as numerous others throughout the world, seemed to line up to past positions of the North Pole. The alignments became even more interesting when I realized that these sites had to be as old as the poles. But how could that be? Humans, or more precisely “modern humans,” could not have built these structures, given that, according to genetic evidence, our ancestors had not yet left Africa.

If modern humans didn’t build these structures, then who did? Aliens? There had to be a better, more scientifically acceptable alternative…
