In 1975 some measurements were made on the pyramid El Castillo and its surroundings, finding that it had been built in vertical cross point of two underground streams located at differentdepths and they passed beneath it at an angle of 89 ° .
The layout sketch on satellite photography indicates about the arrangement of the same and the direction of its movement towards the N-NE.
The closest to the surface current is about 15 or 20 meters below ground level, and its sense of movement to the 022,5º and its width, measured area of about 4.5 meters. its approximate route was determined by a discontinuous series of locations, finding a curve, he came from the cenote Xtoloc and after crossing under the pyramid, addressed the cenote Sacred roughly following the course of the currently existing road between him and the Pyramid .
Current located more depth measurements were performed only in the vicinity of the pyramid, finding that his address was in the directions 113,5º and 293,5º without determining their sense of movement.
Nor it was determined depth, proving that this was only higher than that of the other stream. At that time he was not given another important more than a mere curiosity. Subsequent studies in Europe and North Africa, as well as found for the tomb of Pacal II in the
Temple of the Inscriptions at Palenque, come to provide new data, which convert these past findings, elements that could be important to complete the study the meaning and content of the pyramid-temple Kukulcán.
Analogies between TEMPLE OF ENTRIES AND THE CASTLE
Temple of Inscriptions and crypt of Pacal II
The location and dimensions of the burial chamber or crypt of Pacal II, has a number of notable features regarding hydrology subsoil.
Like the pyramid El Castillo, was constructed by placing it in the vertical crossing of two underground streams that form a very close angle to 90 degrees, orienting it so that its main staircase follows the direction of the closest to the surface current, water below the crosspoint.
The constructive development of the crypt starts from the rectangle formed by the projection surface crossing of both current and extends in the direction of flow of the closest to the surface current, exactly the direction of this and focused her , so it is slightly misaligned with the perpendicular to the front wall of the temple located at the top of the pyramid, as this in turn, follows exactly the projection of the deeper current.
The staircase is also slightly off, as the currents as a result of being a natural process, have geometric irregularities, describing the surface a slight curve, complete the steps, finish away to the 016º, instead of 019º would be the exact perpendicular. This indicates that what might be called “ritual perfection” dominates “constructive perfection”, leading to slight geometric distortions that have all these structures, even though they were carefully chosen their places of location and orientation before beginning His construction.
The vertical section presents some remarkable features as the burial chamber is not built directly on the ground, to be embedded in the mass of the pyramid, but a depth meter and a half is excavated.
Obviously it is looking for a good connection terrain inside the crypt. Even supports on which to place the mass of the stone sarcophagus constructed as it could hinder this connection, if deposited directly on the floor of the chamber. These construction guidelines, of a type that could be defined as “ritual”, are common with European and North African funerary structures.
This coincidence between cultures and times for no apparent connection between them, suggests that obey some technical reason, on which may arise different scenarios, but what is important for the present case is that, at least for the culture of Palenque , they are followed rigorously.
Pyramid El Castillo and the possibility of existence of a crypt.
In this structure, the different archaeological work, have not revealed any burial chamber. This does not mean that it can not exist.
It is analyzing the possibilities of its existence, according to the guidelines “constructive rituals” used by the Maya to the Temple of the Inscriptions.
Archaeological studies have revealed the existence within an older pyramid (430 A.D.) and was probably the first to be built in this place.
The added outer pyramid is merely a display of power and wealth made later, so that constructive rituals guidelines are to be found in the original structure.
Its apex is located vertically above the point of intersection of two undercurrents located at different depths and form each an angle of 89 °, very close to a right angle.
The closer to the surface, which is to be taken into consideration when determining the constructive guidelines, and flows into the 022,5º width detected in surface current it is in the vicinity of 4.5 m. Its depth is of the order of 15 or 20 m. under ground level. After repeated these measurements with sufficient accuracy, it will be possible to place on the ground, the projection surface area covered by a possible crypt, as would start from side N-NE of the quadrilateral formed by the projection of the intersection of two streams, develop into the 022,5º and its width would be equal or less than 4,5m.
Supposing a longitudinal development equal to or less than Palenque Pacal II, it can be set at about 7 m. With these data can be set a rectangular area of 5 x 7 m located adjacent to the crossing point by the N-NE side, which is located exactly plan.
The vertical positioning presents some difficulties since the crypt supposing a height of 6.5 m, the situation can vary from a high position, all high to allow the strength of the pyramid structure that embeds, and a position low which it is limited by the thickness of land under it, that allows stay safely above the underground river on which it is built. This safety thickness can be estimated at about 2 m.
All volume located between these two extreme positions, including themselves, is the situation of a possible crypt.
It happens that if it were located in the upper position, the archaeological work carried out, the had revealed, something that has not happened, so the highest position to consider is one in which the top of crypt possible, is slightly below ground level. It can be estimated at about 2 m.
These considerations can limit the volume to explore at a depth of 10.5 m from 2 m below ground level. Technique used for localization of possible crypt.
Made new measurements with maximum accuracy, may be established in a definitive manner, the exact position of the volume where the crypt could be found.
Be sufficient make a hole from outside of the base of the outer pyramid, with the precise angle inclined to reach in its central area to the volume of probable location.
The diameter of this serious drilling the minimum necessary for him to enter a small camera using a similar to that used in the Temple XX of Palenque technique. This diameter can be estimated at no more than two or three inches.
The inclination to the horizontal is of the order of 15 and drilling length of about 28 m.
By the time the drilling reached a gap in the field, it could be considered inside and check if it was the intended burial chamber.
Thus it is avoided the known alter, while can be carried out with minimal economic cost archaeological structure.
