  1. ent circular feature, known as the Richat Structure, in the Sahara desert of Mauritania is often noted by astronauts because it forms a conspicuous 50-kilometer-wide (30-mile-wide) bull’s-eye on the otherwise rather featureless expanse of the desert. Initially mistaken for a possible impact crater, it is now known to be an eroded circular anticline (structural dome) of layered sedimentary rocks.

  3. He further says that the dating of the death of Atlantis from 11,600 years ago “precisely” matches the date of the Younger Dryas, which was a climactic event which took place between 12,900 and 11,700 years ago. This event was a temporary return to glacial condition, with decreased average temperatures in the northern hemisphere. It primarily affected the norther latitudes, and North America more intensely.

We returned to Ouadane, which is a 1,000-year-old town dangling on the edge of the Sahara wasteland. Beyond it is the most inhospitable desert on Earth. An oasis permits locals to grow date-filled palm trees near the ancient ruins.Very little information is available about the habitat of the Richat Structure or the type of life forms found there. However, the area surrounding the “Eye of the Sahara” is part of a vast desert with rocky and sandy features and sand dunes stretching for long distances. Very little vegetation can be observed on this landscape with vegetation primarily limited to the dry beds of the wadis and the oases. Animal populations are also extremely sparse and very little records of the same exist. The area in and around the Richat Structure experiences very little rainfall and average annual temperatures that are around 27.0° Celsius. El ojo de Gea.

The Richat's structure was revealed to its full extent in 1965 during an American space mission. The Eye of Africa shows what the Earth can offer, a true work of art composed of magnificent and surprising colors in the heart of the world's largest desert Jimmy claims that an event that lasted 1,200 years “precisely” matched an event that was supposed to have happened in one day 100 years after the Younger Dryas ended. Also – there is no reason to think that the Younger Dryas affected the equatorial regions (the Richat structure is at 21 deg latitude). So really, it was in the wrong place and the wrong time for the Younger Dryas to be significant. This is a forced fit that is not compelling at all, but Jimmy thinks it is too amazing a coincidence not to be evidence.

Still, there are countless people who believe that Plato was talking about a real place that was destroyed by a real cataclysm. Plato himself says, in effect, “I know this sounds like nonsense, but I swear I ain’t lyin’.” But we’ve never found evidence, and now that we can image the sea floor, and have found evidence of sunken cities, shouldn’t the fact that we haven’t found Atlantis put this whole thing to bed? Well, what if we haven’t been looking in the right places? What if the ruins of the island-bound seafaring superpower were sitting, right under our noses the whole time, in the middle of the Sahara desert? But the fact that the rings, are equidistant to the centre and that the Richat Structure is nearly circular remains a mystery. Buy Book Ancient Egypt: Uncovered by Brian Foerster. Richat Structure. The Richat Structure contains more than 32 carbonatite dykes which are 1 to 4 meters wide and 300 meters long Plato states that the city of Atlantis was 127 stadia in diameter. According to Dictionary.com, one stadia is approximately 607 feet. This is the conversion used in the video, which works out to 127 stadia equaling 77,089 feet and 23.49 kilometers. Measuring the Richat structure in Google Earth gives a diameter of between 22 and 24 kilometers. That’s pretty close to the measurements for Atlantis. However, other sources say that a stadia is between 607 and 630 feet, which doesn’t seem like a big difference until you realize that 27 feet of variance per stadia, multiplied by 127 stadia, comes out to 3429 feet. While that’s the upper end of the possible variance, it has to be said that the Richat structure would fit the bill a bit less if it was three quarters of a mile too small. It’s not a lot, but it sure wouldn’t be perfectly exact.

He further has to use some creative imagination to argue that the Richat structure, if it were fed by rivers and therefore filled with water, would have two rings of land and three of water. But that is not obvious at all. The rings are not discrete, not complete in places, and it’s unclear how water would fill the structure. You could count four rings of water if you look at the whole structure. A topographic reconstruction of the Eye of the Sahara based on SRTM data and using Landsat Image.

The truth is a trifle less sensational: it’s the remnants of a dome that has taken 100 million years to erode. The eye of Africa in the Sahara desert, Mauritania. It has a diameter of almost 50 kilometres and has been a landmark for astronauts for a long time. It was originally thought to be a meteorite impact crater but know scientists think it was caused by erosion. « L'œil de l'Afrique » (ou structure de Richat), en Mauritanie, dans le désert du Sahara

The Richat structure was first identified from outer space, appearing like a distinct feature among the vast sandy expanse of the otherwise featureless Sahara Desert. Since its discovery, the structure has served as a landmark used by astronauts. Several research institutions have also sent their team of experts to study this structure and various scientific publications describe its unique geology and geography. A video documentary by Radio Canada, the Découverte-L'énigme de Richat (a French title) is based on the Richat Structure. NASA also mentions and describes this structure on their website. Though not very well advertised, a significant volume of tourists visit this structure every year which though in the middle of a desert habitat, is accessible by car from the small town of Oudane.Théodore Monod qui étudia ce phénomène avec ses collègues, publia dès 1973 des hypothèses proches de l'explication communément acceptée aujourd'hui[6].

Mauritania, a country in the western region of the continent of Africa, is generally flat, its 1,030,700 square kilometres forming vast, arid plains broken by occasional ridges and clifflike outcroppings.It borders the North Atlantic Ocean, between Senegal and Western Sahara, Mali and Algeria.It is considered part of both the Sahel and the Maghreb.A series of scarps face southwest. Managed by Digital Gravity Media | Free WordPress ThemeNeuroLogica Blog Copyright © 2020 All Rights Reserved .But an even worse forced fit is the opening to the ocean. Jimmy refers to a sand drift to the southwest – actually more west than south. This is not south. It also doesn’t open up to the ocean, which is to the west. He has to imagine that this part of the Sahara was flooded by the Atlantic 12,000 years ago. That also solves the problem of the Richat not being on an island – well, perhaps it was back then. It did not sink so much as become land-locked. The Richat Structure of Mauritania has captured the attention of astronauts for about as long as NASA has sent humans into orbit around Earth. This circular geologic feature is thought to be caused by an uplifted dome—geologists would classify it as a domed anticline—that has been eroded to expose the originally flat rock layers Le terme pluriel de Richat ou Richât (Rich au singulier), proviendrait d'un mot hassanya (langue arabe parlée en Mauritanie) signifiant « les plumes »[6] ou « les bras de plumes »[7], faisant allusion aux formes de mini-cuestas circulaires.

Le Guelb er Richat apparait pour la première fois sur une carte en 1922 (Service géographique de l'Afrique occidentale française). En 1934, Théodore Monod est le tout premier explorateur et scientifique à visiter cette étrange formation (le fac-similé de son carnet d'exploration pour la journée du 7 juillet 1934 a été publié dans B.

Depuis les années 2000, il est acquis que la structure de Richat est issue d'une forme rare de volcanisme géant, vieux de 100 millions d'années (Crétacé), qui a créé un dôme magmatique associé à des remontées hydrothermales. Il ne s'agit cependant pas d'un volcan car aucune lave n'est jamais parvenue en surface. Selon certains scientifiques, le terrain en place situé au-dessus du dôme, composé de sédiments déformés par la poussée, se serait effondré à la suite d'une longue et lente érosion karstique[3], ce qui expliquerait la présence importante de brèches au centre de la formation. Chinguetti and Ouadane are UNESCO World Heritage Sites because they are vestiges of the once-flourishing civilizations that existed during the era of the Trans-Sahara salt trade.

  1. Extensive sand dunes occur in this region and the interaction of bedrock topography, wind, and moving sand is evident in this scene. Note especially how the dune field ends abruptly short of the cliffs at the far right as wind from the northeast (lower right) apparently funnels around the cliff point, sweeping clean areas near the base of the cliff. Note also the small isolated peak within the dune field. That peak captures some sand on its windward side, but mostly deflects the wind and sand around its sides, creating a sand-barren streak that continues far downwind.

It had been so long since he had come, Alioune wasn't sure if we were in the Richat Structure or not. Ultimately, he concluded that we hadn't found it. He was wrong. The Eye of the Sahara is also known as The Richat Structure is a geological feature that has a diameter of almost 30 miles. It is located in the Sahara desert in Mauritania and can be seen from space, in fact, it has become a landmark for shuttle crews. It is believed to be a highly symmetrical and deeply eroded geologic dome that collapsed Concentric rings are not uncommon in nature, as there are several natural processes that can create them. Impact craters come to mind, but this Richat structure is not an impact crater. It is an eroded dome of magma. Jimmy admits that it is a natural structure, but gets around this massive problem by simply claiming that the Atlantians built their city into the natural formation.
