Strange phenomenon: SB Identity filmed in Ravne Tunnels@Bosnian Pyramids
This is a strange phenomenon that we observed in December 2010 after opening the new section of tunnel Ravne. These small clouds of fog that formed suddenly and move independently, without following the flow of air.

New images come from the Bosnian valley of the pyramids. The leading archaeologist of the Foundation APBPS, Mrs. Dr. Sara Acconici, team member of the Italian SB Research Group and now a permanent resident of Visoko, has descended recently in the new tunnel sections accompanied by an Italian archaeological speleologist. These brave researchers have entered more than 120 meters inside the flooded tunnel labyrinth and they stopped only when the water level reached a considerable height.
However, they were able to take some very interesting images.

Abstract: The objective of our research included the audio gamma recording of the ultrasound vibration coming out of the Sun Pyramid and pointing towards outer space as already detected by other researchers coming before us. For this experiment we used a compander in order to turn ultrasound vibrations into audible sounds. Results were astounding, but we will carry out the experiment again during our next expedition at the end of February, in order to verify if results are scientifically reliable and can be repeated by means of a very rigid protocol for each recording. Therefore, so far present results have to be considered preliminary.
SB Research Group – January 28th, 2011.
The objective of our research included the audio gamma recording of the ultrasound vibration coming out of the Sun Pyramid and pointing towards outer space as already detected by other researchers coming before us. The scientific expedition left Trieste on January 23rd, 2011 and included only three researchers: Lucia Krasovec Lucas, architect, expert of ancient structures, Valeria Hocza, scientific assistant and myself, Paolo Debertolis, anthropologist. On site there was also the chief worker of the excavations in Ravne’s maze, Amir Suša www.sbresearchgroup.eu.
The research was carried out in two days from January 24th – 25th, 2011.

Unfortunately on the first day a snowstorm deposited on our path more than a metre of snow.
We immediately realized we could not get to the plateau west of the Sun Pyramid by car, despite the four-wheel drive which could have saved us a good distance to reach the top. Therefore we had to walk with our boots and gaiters from the foot of the Sun Pyramid, up to the top with the snow still falling.

Photo: Despite the difficult climb and the snow storm, the scenery between one snowfall and another was amazing.
In order to reach the top we had to walk along the path starting at the bottom of the Sun Pyramid on the most eastern portion of the northern facade; more or less below the first excavating surveys. Afterwards the path rounds the eastern facade with two hairpin bends and then reaches the southern facade, the most ruined part, owing to trenches dug by different armies to approach the western part at the crossroads with the plateau.
From there, even with the best weather conditions, one must walk to the top, dominated by the medieval fortress destroyed by the Ottomans after conquering Bosnia at the end of the Middle Ages.


Photo: Different sceneries from winter to summer in the path leading to the Sun Pyramid.
This is the plateau west of the pyramid. Also during the last Balkan war the top of the pyramid was a strategic place guarded by the Serbian Army for the whole war until Dayton’s agreements stopped the last war in Bosnia (November 21st, 1995), after three years of the bloodiest war in Europe since 1945.
The idea of recording ultrasound frequency with a compander was put forward by our instrument expert, Giorgio Battistoni, who built one on purpose for our team, by developing a consolidated project published by a well known Italian Journal on Electronics.
Companders are processors of sound dynamics belonging to a group of electronic devices operating essentially on the level or width of the audio signal variations depending on the range of levels and the spectrum distribution of the compandor itself.
The compandor used by our team could turn ultrasound vibration into audible sounds.

Materials and methods
It has often been cleared that an apparently innatural 28-KHz ultrasound frequency originates from the Sun Pyramid and Vratnica mound.
Ultrasounds can be briefly described as mechanical waves that we cannot hear even if they reach our ear because their frequency is higher than the maximum frequency detected by human beings. Actually because of its nature, the human ear can convey to the brain – which will then turn them into sounds – only acoustic waves having frequencies between 20 Hz and 20.000 Hz, even though not all individuals can detect these degrees. Therefore frequencies lower than 20 Hz and higher than 20.000 Hz cannot be detected by human beings as sounds, whereas many animals can hear frequencies lower than 20 Hz and others higher than 20.000 Hz (or 20 Kilo Hz).
However there are instruments suitable to detect frequencies overcoming our hearing abilities; on the Sun Pyramid actually such instruments recorded sounds with 28.000 Hz frequency.
Yet one thing is reading 28 KHz on a scale or on a display, another thing is listening or analysing that emission confirmed by the instrument.
To achieve this we benefitted from a project published by an Italian Journal, which is well known for the manufacturing of electronic kits not available on the market. The Journal’s name is Nuova Elettronica.
Issue 245 of 2010 published a project that could prove useful for our research, i.e an instrument able to “convert ultrasounds into audible sounds”.
Instrument’s features
This project takes advantage of the ability of a particular microphone, which can be defined more correctly a supersonic sensor. Such sensor detects sounds whose frequency ranges between 10 and approximately 65 KHz. The circuit diagram is displayed in the following figure.

Briefly one part of the instruments generates a variable frequency thanks to a knob and from that frequency the instruments withdraws the frequency received by the microphone. The result of such withdrawal can be heard into the headphones. For example, let us suppose that the microphone is detecting a 40 kHz-frequency (not audible); if, by rotating the tuning, we produce a 50-kHz frequency we will hear a difference between 50 and 40 kHz, i.e. a 10-KHz sound and it will be an audible frequency.
The signal coming from the sensor is then applied to an amplifier and the tension gain at this stage is approximately 100 times. In order to hear ultrasounds detected by a microphone, they need to be “conveyed” to a lower frequency, in order for them to be heard by a human being. The system we used is similar to that used in several radio receivers, in which the high frequency signal of dozens or hundreds MHz is lowered deeply compared to the incoming signal.
The instrument uses a variable beat-frequency oscillator and a two-entry mixer, used to produce an outgoing signal equal to the difference between the frequencies of the incoming signals, one generated by the instrument and the other coming from the microphone. The first frequency can be tuned with a tuner, as if looking for a radio station. The “different” signal is then cleared from possibile tension peaks and is conveyed to the second part of the intrument which amplifies it and conveys it to the headphones and/or to a recorder. The volume can be tuned.
The instrument’s wire diagram is the following:

The equipment is included in a plastic container and powered by a 9 Volt battery.
The supersonic sensor we used (technical sheet here) has been manufactured by the American company Knowles Acoustics and, despite its very small size, it implies very advanced technology: the equipment contains highly miniaturized mechanic and electronic components integrated in the same silicon substratum.
A further, but important technical detail is the assembly of the small microphone on the focal point of a metal parabola, so as to collect the very straight ultrasound waves at best.

To use the instrument, the parabola with the microphone must aim towards the direction to be examined, and by rotating the tuning potentiometer, ultrasound waves can be detected (if present), heard in the headphones or recorded if a tape or digital recorder is connected. This is just the beginning of the use of these instruments to ultrasound detected on the top of the Sun Pyramid. One can listen to the released sound, but at a lower tone, since the real sound is so high-pitched we could not imagine; the interesting feature to be searched is a possibile sound modulation. This is what we will try to do during the analyses of the different recordings.
Further equipment
For our measurements of possibile raioactivity we used a GAMMA-SCOUT w/ALERT portable Geiger counter manufactured in Germany with a steel-coated GM tube filled with halogen gas, dosing of alpha, beta and gamma rays, rotating discriminator.
It is a very compact and portable equipment with internal memory which records radiation trends in the different periods and USB port to download measurements on the PC.
To look for magnetic fields, we used a EMF Tester PCE-G28 equipped with 3D external probe and a wide LCD display.
By placing the probe in the interested area this instrument enables the measurement of the magnetic field on the three axis without moving the probe in the space.
The experiment
A preliminary remark must be made. Three scientific teams already used instruments to detect the presence of an ultrasound beam coming from the top of the Sun Pyramid and pointing to the sky.
The first team to notice this ultrasound frequency released at the top of the Sun Pyramid was a group of Croatian researchers, who came in the Bosnian Pyramids’ Valley on April 10th and 11th, 2010, led by the physicist Slobodan Mizdrak, from Zagreb. The instruments used in their research were an 823 EMF gaussmeter with internal probe and an 828 EMF gaussmeter with a 3D external probe, gauged in the factory. [ Energetic Radiation from the Bosnian Pyramids ]
Two devices have been used to analyse the frequency: an oscilloscope and a spectrometer.
This discovery has been confirmed later by a team of the Russian Geophysical Institute Schmidt of Moscow (Dr. Khavroshkin and Dr. Tsyplakov).
Finally, again in 2010, Dr. Harry Oldfield, a British independent researcher detected the electromagnetic fields above the Sun Pyramid with a special camera using the Polycontrast Interference Photography technique (PIP camera, an evolution of Kirlian’s camera). He was able to reveal the ultrasound radiation accumulated in the pyramid as well as its release through the top.
The main features of the ultrasound frequency were a continuous emission of 28.000 Hz. During the Croatian team’s walk to the top of the Sun Pyramid, instruments did not show ultrasound frequencies on the whole western side. Such frequency appeared surprisingly only at the top of the pyramid and only within a metre’s radium. Outside a 5-meter diameter no sound could be detected by the instruments.
The Zagreb (Croatia) team detected the same emission frequency (28kHz), and even the same sinusoidal shape, also at the centre of the plain placed at the top of Vratnica’s barrow, but also in a few passages on the sides of Ravne’s underground complex.
Therefore we decided to carry out a different survey. We wanted to record the “voice” of the pyramid with the compander. We also brought a gaussmetre equipped with 3D external probe and a Geiger counter.

Photo: We have looked all over the top for the right position of the ultrasound beam emission.
Once we reached the top, unfortunately the wind and the snow created many interferences and we had to keep the microphone’s protection cap on at the centre of the compandor’s parabola, in order to avoid spurious influences.
We had to explore many places on the flat top of the pyramid before detecting the ultrasound radiation outside the walls of the Medieval citadel at the highest spot of the top, slightly westwards.


Photo: Despite the snowstorm and the cold weather we managed to find the origin of the strong ultrasound beam.
By using our hearing as a reference, we discovered that the ultrasound beam is much wider compared to what the Croatian team reported after catching it only on their instruments’ displays.
The sound can be heard as a continuous whistle, and tends to fade away by withdrawing from the top progressively and not abruptly.
Unfortunately the recording is disturbed by the wind which can be clearly heard, our voices and the voices of two boys who followed us to the top maybe intrigued by our instruments, and even the continuous barking of the boys’ dog.
Unfortunately, after half an hour of analyses and approximately fifteen minutes of recording we had to interrupt the experiment and go downhill because of the worsening of the very cold weather and dusk coming in rapidly.
First we checked if in the same place there was an anomalous gamma radiation with the Geiger counter or if there were magnetic fields. The radiation we detected was the natural one, contained into normal ranges recorded all over Bosnia (0,06.-0,22 μSv/h).


Photo: Radioactivity levels were perfectly normal where ultrasounds could be detected. During the photo shooting we detected only 0,10 μSv/h on the Geiger counter.
Similarly we looked for magnetic fields with the gaussmeter equipped with a 3D probe. In this case too the analysis was negative: there is no magnetic field on top of the Sun Pyramid.


Photo: No magnetic field can be detected by the gaussmeter with 3D external probe on top of the Sun Pyramid. This last data is very important because the whistle cannot be referred to radio waves originated by radio stations or repeaters placed nearby.
The whistle, turning the 20.000 Hz vibration into an audible sound can be clearly heard even though it is disturbed by other sounds (two small parts of the non-processed original recording, can be downloaded here:
http://files.podsnack.net/app/swf/EmbedCanvas.swf?hash_id=272022eddf5db8366f106292ea322908
![]()
(In the first recording our voices and the dog’s barking overlap the sounds, the second recording has been carried out on a different ultrasound frequency, besides a different emission frequency and the children’s voices overlap; in both recordings the wind blowing can be heard sometimes).
However, having learned from experience, on the next day we wanted to go in other areas around the Sun Pyramid to verify if this vibration could be felt in other places too. For this reason we reached several excavation survey sites on the northern facade and started measurements.
The walk was shorter than the previous day, but not less impracticable, with more than a half-metre snowfall and a short uphill path.
At the Deset Probe (survey number ten), placed in the lower two thirds of the northern facade, almost setting the microphone’s parabola on the ground, we detected a similar ultrasound frequency, i.e. a continuous whistle, yet also coupled to a series of bursts, as if the wind were blowing into the microphone.


Photo: Measurements on the Deset Probe have been carried out more rigorously and with the instrument’s maximum sensitivity.
However that day, despite the heavy snowfall, the sun shone again and there was no wind. The microphone was well secured to the main instrument, without anomalous contacts.
Such sounds cannot be heard by human ears and therefore can be ascribed to the womb of the Sun Pyramid. We make this recording available, even though our voices overlap them. At a certain point the change in the whisle is due to a small tuning shift. Background noises are not caused by wind nor by clothes or cables.

Graphic spectral analysis of 5 seconds of the ultrasound recorded on the Deset Probe (analysis by Giorgio Battistoni).
The idea we came up with is that at Deset Probe level there is some sort of energy leakage present inside the pyramid. But this is only theory, so far not supported by evidence.


Photo: The Deset Probe in today’s version (winter) and in the Fall (November 2010) .
Obviously our next mission at the end of February will include the repetition of the experiment in order to verify if results are scientifically reliable and replicable. Moreover we will implement a very strict protocol for all recordings. Therefore, so far present results have to be considered preliminary.

Photo: Inside Ravne’s tunnels complex we did not detect the ultrasound frequency coming from the Sun Pyramid.
Possibile ultrasound catching inside Ravne’s underground complex was disappointing. No unusual vibration was detected except below the monolyths where there are underground water flows which could generate such vibrations, softened by the megalyths. However this part is still being studied.

Bosnian pyramids: Photos of the ravne tunnel complex
posted from:http://forum.davidicke.com/showthread.php?t=118565&page=4
This is probably the best example of a photographed orb within my photos of the Ravne tunnel complex. Ive so many, so no doubt more will turn up.
You see to the right of the photo is another dry stone wall within the tunnel fill which was excavated that day.
These walls indicate to us that the tunnel fill could not have been a natural deposit because dry stone walls dont form in natural deposits!
The Drywalls are positioned at intersects along the main passage where smaller side passages branch off. These are also filled in the same way as the main passageway. The material is unconsolidated and can be pulled from the tunnel walls quite easily.
The board on the floor protects various stones which are below. Larger boulders are placed along the floor of the tunnel at various positions. The actual tunnel floor is 30cm below what we are working on.
The position of these stones almost certainly has some importance and must be studied further.
These are the typical objects that get pulled out daily from the tunnel fill material

Much of this material here is either shaped stone or an artificial composition ie concrete.
Similar material can be identified in situ on the moon pyramid. This could indicate that the tunnels were filled in after the construction of the pyramids. Someone may have filled the tunnels with all the waste material. As you can see much of the material is broken and eroded bricks/tiles.
The white ball of material in the left corner is a sandy limestone. This material may have been used for the creation of a binding agent in the concrete.
The dark coloured artifact (Bottom, centre-left) is part of a larger slab made up of 4 pieces in total.
Each piece was pulled out in close succession over 2 days. There are markings across all four pieces. Someone had broken the complete slab and then buried it within the tunnel.

Here you can see the clear difference in colour between the natural post glacial deposit the tunnels are cut into and the material filling the tunnel.
The tunnel fill is a mix of unconsolidated sand, bands of clay and mixed sized boulders. Orientation of the stones and boulders are random. There is no preference for orientation as there would be if the material were deposited by water.
This and the fact there are dry stone walls within the fill gives us confidence in the idea that the tunnels were purposely blocked up.
The next step is to figure out whether it was blocked up from the outside, or from the inside.

Here is an interesting artifact!
Look closely and you can see the head is that of a bird.
New photos from the Bosnian pyramids
posted from: http://forum.davidicke.com/showthread.php?t=118565
We found another pyramid yesterday, bringing the total number of structures to 6 here in Visoko.
I got to meet some Bosnian government officials today, they seem very nervous of the whole thing.
Got myself on Bosnian national TV today as well haha. Madness.
Ive had about 4 interviews for the national press, people in Bosnia all know of these pyramids, tho most dont believe it. Many of the ppl living in the town where the Sun Pyramid towers over refuse to accept the reality. They are all nervous for what it means.
The weather has been very cloudy in the morning so Ive had no chance to get some good shots of the actual Pyramids cos they are covered in cloud.
Ill show you some photos of the labyrinth system. These are 100s of KMs of tunnels which connect all the pyramids in the complex.
At some point in the past every inch of these tunnels were filled in with rocks, sand and clay. It takes a team of miners a whole day to move about 4m deeper into the tunnels, just to get an idea of the scale we are talking about.
Also, something amazing, there are large megaliths placed around the tunnels. Dowsing shows that water is below these rocks.
One has 2 separate flows intersecting creating an energy vortex.
Now, in outside air it is usually 1000ppm ionised atoms. Next to these large stones the ionized particles increases to 36000 ppm. The air is fresher, cleaner and healthier within the tunnels than outside in the open country.

Here is the block with symbols carved. There is also a Swastika. Sorry the detail isnt very clear. Bad light.


This is the end of the tunnel with the debris extracted. The wall in front is the material we are removing.

This is one of the Megaliths

Section of the tunnel. Imagine you are a grey alien and the size of this passageway is a perfect fit. Not made for tall modern man.


Tony Robinson eat your heart out!

Main tunnel splits off into 2 separate passages. We have decided to concentrate our efforts on the Right hand side passage.

Pyramid of the Moon (left), Temple of Mother Earth (right) which is more of an elongated curved pyramid. The Moon pyramid has a terrace rather than a peak, similar to some S.American Pyramids.

Excerpts from “The Bosnian Pyramid of Sun”, by Semir Osmanagic;
published by Klepsidra Sarajevo, October 2005, first edition.
12,500 years ago a large part of the European continent was under deep layers of ice. Areas of Southern Europe from France through Spain, Italy, Croatia, Bosnia, Turkey and Caucasian areas have grown rapidly with human cultures.
Developed societies of the Pacific, Atlantic and Mediterranean have left a strong outline on the architecture, social organization and spiritual life of people in Southern Europe . Bosnia and Herzegovina as well as the Adriatic rim has been important as a potent energy source for them.
Ranging a few hundred kilometres from river Sava to the Adriatic Sea, Bosnia and Herzegovina was considered one of the most outstanding areas in Europe at that time. Several millennium inaugurals of Illyrian and Basque-Caucasian people left behind genius facilities in the form of pyramids, monolithic towns formed in stone and complex energy harvesting systems.
12,000 years ago a universal cataclysm, which resulted in the ice melting in most of Europe , caused a few hundred-meter rise in the sea level. Civilizations were under the sea. Soon after, the water retreated and during the centuries that followed soil and maquis covered the pyramids.
Now we have a rare opportunity to lay a hand on the remnants of our ancestors. We can foresee a mosaic using several accessible pictures. A mosaic that makes Bosnia and Herzegovina an archaeological treasure.
Seventeen lost pyramids found in new infra-red satellite survey of Egypt

More than 1,000 tombs and up to 3,000 ancient settlements were revealed by infra-red images taken of the desert in Egypt.
The work has been pioneered by US Egyptologist Dr Sarah Parcak from the University of Alabama in Birmingham, US.
She told the BBC she was amazed at the number of buildings and settlements that showed up on the images.
‘We were very intensely doing this research for over a year. I could see the data as it was emerging, but for me the “Aha!” moment was when I could step back and look at everything that we’d found and I couldn’t believe we could locate so many sites all over Egypt,’ Dr Parcak explained.
The pyramids are thought to have been covered by silt from the Nile and Dr Parcak believes there could be thousands more sites of interest further beneath the desert’s surface.
Two test excavations have been carried out at Saqqara which revealed two lost pyramids, with the area now being described as one of the most important archaeological sites in Egypt.
The discovery of the forgotten pyramids is part of a new BBC documentary titled ‘Egypt’s Lost Cities’, which airs on BBC1 on May 30th.
Strange signs found at Egypt’s Pyramid of Giza
The markings, which have lain unseen for 4,500 years, were filmed using a bendy camera small enough to fit through a hole in a stone door at the end of a narrow tunnel.
It is hoped they could shed light on why the tiny chamber and the tunnel — one of several mysterious passages leading from the larger King’s and Queen’s chambers — were originally built.
The markings take the form of hieroglyphic symbols in red paint as well as lines in the stone that may have been made by masons when the chamber was being built.
According to Peter Der Manuelian, Philip J. King Professor of Egyptology at Harvard University, similar lines have been found elsewhere in Giza. “Sometimes they identify the work gang (who built the room), sometimes they give a date and sometimes they give guidelines to mark cuttings or directional symbols about the beginning or end of a block,” he said.
“The big question is the purpose of these tunnels,” he added. “There are architectural explanations, symbolic explanations, religious explanations — even ones relating to the alignment of the stars — but the final word on them is yet to be written. The challenge is that no human can fit inside these channels so the only way to do this exploration is with robots.”
Pictures of the markings have been published in the Annales du Service Des Antiquities de l’Egypte, the official publication of Egypt’s Supreme Council of Antiquities, following an international mission led by the Minister for Antiquities.
The robot explorer that took the images is named Djedi, after the magician whom Pharaoh Khufu consulted when planning the layout of the Great Pyramid. It was designed and built by engineers at the University of Leeds, in collaboration with Scoutek UK and Dassault Systemes, France.
Although robots have previously sent back pictures from within the pyramid’s tunnels, Djedi’s creators say it is the first to be able to explore the walls and floors in detail, rather than just take pictures looking straight ahead, thanks to a “micro snake” camera.
The camera also scrutinized two copper pins embedded in the door to the chamber at the end of the tunnel. In a statement, Shaun Whitehead, of Scoutek UK, said: “People have been wondering about the purpose of these pins for over 20 years. It had been suggested that they were handles, keys or even parts of an electrical power plant, but our new pictures from behind the pins cast doubt on these theories.
“We now know that these pins end in small, beautifully made loops, indicating that they were more likely ornamental rather than electrical connections or structural features. Also, the back of the door is polished so it must have been important. It doesn’t look like it was a rough piece of stone used to stop debris getting into the shaft.”
The team’s next task is to look at the chamber’s far wall to check whether it is a solid block of stone or another door.
“We are keeping an open mind and will carry out whatever investigations are needed to work out what these shafts and doors are for,” said Whitehead. “It is like a detective story, we are using the Djedi robot and its tools to piece the evidence together.”
Tunnel found under temple in Mexico
Researchers found a tunnel under the Temple of the Snake in the pre-Hispanic city of Teotihuacan, about 28 miles northeast of Mexico City.
The tunnel had apparently been sealed off around 1,800 years ago.
Researchers of Mexico’s National University made the finding with a radar device. Closer study revealed a “representation of the underworld,” in the words of archaeologist Sergio Gomez Chavez, of Mexico’s National Institute of Anthropology and History.
Experts found “a route of symbols, whose conclusion appears to lie in the funeral chambers at the end of the tunnel.”
The structure is 15 yards b0eneath the ground, and it runs eastwards. It is about 130 yards long.
“At the end, there are several chambers which could hold the remains of the rulers of that Mesoamerican civilization. If confirmed, it will be one of the most important archaeological discoveries of the 21st century on a global scale,” Gomez Chavez said late Thursday.
Teotihuacan, with its huge pyramids of the Sun and the Moon, its palaces, temples, homes, workshops, markets and avenues, is the largest pre-Hispanic city in Mesoamerica. It reached its zenith in the years 300-600 AD.
