Explore Richat Structure in Mauritania as it appears on Google Maps and Bing Maps as well as pictures, stories and other notable nearby locations on VirtualGlobetrotting.com. The image shows the Adrar plateau on the left side with darker sedimentary rocks. The Richat Structure, also known as the Eye of the Sahara and Guelb er Richat, is a prominent circular feature in the Sahara desert near Ouadane, west–central Mauritania.This structure is a deeply eroded, slightly elliptical, 40 km in diameter dome.

Land. by the Advanced Visible and Near Infrared Radiometer on Japan’s ALOS satellite. The Richat Structure is a fascinating, circular area located in the Sahara’s Adrar Plateau in Mauritania. Image of the Day large dome of molten rock uplifting and shaped by the forces of water and wind. This prominent 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. Google Maps was created in 2005 to open up the world to people from their computer..

Sand Dunes, Marzuq Sand Sea, Southwest Libya, NASA Goddard Space There is no positive evidence to directly tie the two together or of an ancient civilisation in the Richat, but it is in the right place, matches the geography of Plato’s Atlantis, and … Namibia’s sea of sand is bounded on its northern side by the impermanent Kuiseb River. The Richat Structure, also known as the Eye of the Sahara and Guelb er Richat, is a prominent circular feature in the Sahara desert near Ouadane, west–central Mauritania. Layers of dunes march across a sand sea in the east-central Tenéré Desert of Niger in this astronaut photo from December 1, 2009. Despite the dry and inhospitable look of this region of the Sahara Desert the southern part of the Richat Structure shows the presence of vegetation in the form of trees and bushes as well as temporary lakes; a result of the rainy season that occurred a few weeks before the picture was captured. Also known as the Eye of the Sahara, the structure measures 40 kilometers (roughly 25 miles) in diameter.

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. This prominent 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. Also known as the Eye of the Sahara, the structure measures 40 kilometers (roughly 25 miles) in diameter. This view was generated from a Landsat satellite image draped over an elevation model produced by the Shuttle Radar Topography Mission (SRTM).

The view uses a 6-times vertical exaggeration to greatly enhance topographic expression. It was originally though to have been caused by a meteor strike, but scientists now believe it was formed by a large dome of molten rock uplifting and shaped by the forces of water and wind. Other sources mention a large island in the Atlantic Ocean, at some … Extensive sand dunes occur in this region and the interaction of bedrock topography, wind, and moving sand is evident in this scene. The image shows the Adrar plateau on the left side with darker sedimentary rocks. Land The sedimentary rock exposed in this dome ranges in age from Late Proterozoic within the center of the dome to Ordovician sandstone around its edges. This astronaut photograph shows classic large and small sand masses of the central Sahara Desert, where wind is a more powerful land-shaping agent than water. Note also the small isolated peak within the dune field. Differential erosion of resistant layers of quartzite has created high-relief circular cuestas. Latitude: 21° 07' 17.80" NLongitude: -11° 24' 7.77" W, Satellite map of Richat Structure in Google Maps. The Richat Structure, also known as the Eye of the Sahara and Guelb er Richat, is a prominent circular feature in the Sahara near Ouadane, west–central Mauritania.

It has since captured some of the weirdest and unsolved mysteries of the world. 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. Initially mistaken for a possible impact crater, it is now known to be an eroded circular anticline (structural dome) of layered sedimentary rocks. Land. A fracking-fueled demand for round and durable sand has triggered a mining boom in the western part of the state. The Richat Structure, a geologic wonder viewable from space, is a striking circular feature found in the Sahara Desert in Mauritania. Sedimentary rock is found between the ridges. The sedimentary rocks comprising this structure dip outward at 10°–20°. The Richat Structure, a geologic wonder viewable from space, is a striking circular feature found in the Sahara Desert in Mauritania. Some shading of the elevation model was included to further highlight the topographic features. Interactive 3D View If you would like a custom relief map, contact me through my website or through Shapeways. A geologic dome, the Richat Structure has concentric bands of resistant quartzite rocks which form the ridges. Study Finds Staggering Decline in Marine Fishery Biomass, Three of Colorado’s Wildfires are the Largest in Recorded History for the State, Rapid Growth Shortens Trees’ Lifespans – and Adds to the Climate Crisis. Many people believe it is also the site of Atlantis. The lower portion of the images shows the erg (sand dunes). For vertical scale, note that the height of the mesa ridge in the back center of the view is about 285 meters (about 935 feet) tall. resistant quartzite rocks which form the ridges.

This prominent circular feature in the Sahara desert of Mauritania has attracted attention since the earliest space missions because it forms a conspicuous bull's-eye in the otherwise rather featureless expanse of the desert. Image of the Day
