Earth's Richat Structure - January 5th, 1998.

"What on Earth is that? The Richat Structure in the Sahara Desert of Mauritania is easily visible from space because it is nearly 50 kilometers across. Once thought to be an impact crater, the Richat Structure's flat middle and lack of shock-altered rock indicates otherwise. The possibility that the Richat Structure was formed by a volcanic eruption also seemed improbable because of the lack of a dome of igneous or volcanic rock. Rather, the layered sedimentary rock of the Richat structure was thought by many to have been caused by uplifted rock sculpted by erosion."

"The Richat Structure, sometimes referred to as the Bull's Eye, can be seen in northwest-looking view. Contrary to a commonly believed notion, the structure was not made by the impact of a meteorite. The 24 mile (39km) wide structure was made by the erosion of layers of rock which domed upward. The depression or pit in which the domed rock rings sit is 328 feet (100 meters) deep from the surrounding plateau area (darker colored rock). The rock layers themselves are thought by many scientists to be several hundred million years old, and their variable resistance to erosion has produced a series of concentric ridges in the structure stepping down from the outside in. The structure is surrounded by fields of sand which is visible encroaching into the southern part of the structure. Small dry lakes or playas (whitish-gray color) are discernible to the east of the center part of the structure."

I’m bored so let’s start a reblog game! Reblog with your favorite conspiracy theory, no matter how wild it is

I’ll start— my favorite conspiracy theory is that the Richat Structure is actually the remains of Atlantis!

The Eye of the Sahara: A Mystery Older than Humans

Known as the Richat Structure, the Eye of the Sahara is one of the most interesting and impressive geological formations. It is in the Sahara Desert, stretches for 40 km, and looks like a bullseye. The eye is so huge that it can be seen from space and astronauts use it as a visual landmark. It was first photographed by Gemini Project astronauts in the 1960s.
