Eye of The Sahara

Located in Mauritania, the Eye of the Sahara also known as the Richat Structure is a huge circular formation; it was originally thought to be a crater. It has been studied by numerous geologists. And for a while, scientists did think that the Eye of the Sahara was an impact crater. But they didn't find enough melted rock to make that guess hold water. Current theories suggest a much more complicated story behind this incredible natural formation but the more recent and accepted theories suggest that it is, in fact, a product of erosion that took place in geological time.

Two Canadian geologists think that the Eye's formation began more than 100 million years ago, as the super-continent Pangaea was ripped apart by plate tectonics and what are now Africa and South America were being torn away from each other.

Molten rock pushed up toward the surface but didn't make it all the way, creating a dome of rock layers, like a very large pimple. This also created fault lines circling and crossing the Eye. The molten rock also dissolved limestone near the center of the Eye, which collapsed to form a special type of rock called breccia.
 


A little after 100 million years ago, the Eye erupted violently. That collapsed the bubble partway, and erosion did the rest of the work to create the Eye of the Sahara that we know today. The rings are made of different types of rock that erode at different speeds. The paler circle near the center of the Eye is volcanic rock created during that explosion.

The main ring structure of the Eye is the eroded remains of what was once a dome of layers of Earth's crust.

According to zmescience, “The Richat structure (Sahara, Mauritania) appears as a large dome at least 40 km in diameter within a Late Proterozoic to Ordovician sequence. Erosion has created circular cuestas represented by three nested rings dipping outward from the structure. The center of the structure consists of a limestone-dolomite shelf that encloses a kilometer-scale siliceous breccia and is intruded by basaltic ring dikes, kimberlitic intrusions, and alkaline volcanic rocks”

Some people believe that the Eye of the Sahara is actually the remains of the city of Atlantis, which Plato described as concentric rings of water and land.

1,600-Year-Old Skeleton Found In Ancient Ruins of Teotihuacan

On early July 2016, a team of archeologists have discovered the 1,600-year-old skeleton of an upper-class woman whose skull was intentionally deformed and teeth were encrusted with mineral stones near Mexico's ancient ruins of Teotihuacan. She was buried in the Barrio Oaxaqueño neighborhood, also known as Tlailotlacan meaning “people from distant lands.” Judging from her extensive body modifications, she lived up to the neighborhood’s billing.

The woman, between 35 and 40 years old when she died, was buried with 19 jars that served as offerings, the National Anthropology and History Institute said. Her cranium was elongated by being compressed in a "very extreme" manner, a technique commonly used in the southern part of Mesoamerica, not the central region where she was found.


Her teeth are of particular note. The central incisors in her upper jaw are embedded with round pyrite stones. This technique required cutting a hole in the enamel of the tooth and inserting the decorative stones. It was practiced in the Mayan cities of southern Mexico (see the jade tooth inserts found in Uxul on the Yucatan peninsula), Guatemala and Belize. One incisor in her lower jaw was replaced with a prosthetic made of serpentine, a green stone carved in the shape of a tooth. This was not of local manufacture and she must have worn it for many years because it shows signs of wear and tartar growth. Researchers are currently studying this tooth looking for evidence of how it was affixed to the jaw, possibly with a cement-like adhesive or some kind of fiber that held it in place.

Her teeth and skull make hers one of the most extensively modified bodies ever discovered at Teotihuacan. It also confirms that the residents of Tlailotlacan weren’t only labourers who were brought to or moved to the big city for work, but people of wealth and status as well. The Lady of Tlailotlacan’s modifications were reserved for the Maya elites.

Squonk

Squonk is a mythical creature reputed to live in the Hemlock forests of northern Pennsylvania. Hunters who have attempted to catch squonks have found that the creature is capable of evading capture by dissolving completely into a pool of tears and bubbles when cornered. The legend holds that the creature's skin is ill-fitting, being covered with warts and other blemishes and that, because it is ashamed of its appearance, it hides from plain sight and spends much of its time weeping.

Legends of squonks probably originated in the late nineteenth century, at the height of Pennsylvania's importance in the timber industry. The distribution was once fairly wide, the usual habitat being high plains where desert vegetation was abundant. History shows beyond dispute that, as these areas gradually changed to swampy, lake-dotted country the Squonk was forced to take to the water. Of distinctly low mentality it traveled constantly around the unacustomed marches in search of fodder. With time, it developed webbing between its toes, but only on the submerged left feet. Hence, on entering the water it could swim only in circles, and never got back to shore. 



The squonk is of a very retiring disposition, generally traveling about at twilight and dusk. Because of its misfitting skin, which is covered with warts and moles, it is always unhappy ; in fact it is said, by people who are best able to judge, to be the most morbid of beast.

Mr. J. P. Wentling, formerly of Pennsylvania, but now at St. Anthony Park, Minnesota, had a disappointing experience with a squonk near Mont Alto. He made a clever capture by mimicking the squonk and inducing it to hop into a sack, in which he was carrying it home, when suddenly the burden lightened and the weeping ceased. Wentling unslung the sack and looked in. There was nothing but tears and bubbles.

Moonlight nights are best for Squonk hunts, for then the animal prefers to lie quiet in its hemlock-home, fearing, should it venture forth, that it may catch a glimpse of itself in some moonlit pool. Sometimes you can hear one weeping softly to himself. The sound is a low note of pleading somewhat resembling the call of the Cross-feathered Snee.
