The Delta contains a tiny island called El Ojo that rotates on its own. It is a perfect circle that is encircled by a ring with a diameter of more than 120 meters and rotates around its own axis. Just a thin layer of water in the middle.
At least 30 years have passed since the 120-meter circle first appeared and began to move. Its formation, rotational timing, and motivation are all unknown.
El Ojo is a neighborhood in Buenos Aires, Argentina's Paraná Delta. It can be located on Google Maps by entering the coordinates 34° 15'07.8'S and 58° 49'47.4'W.
Scientists are working hard to solve the mystery. So they made the decision to start a campaign to raise money and learn more about this mystery that is still unsolved.
The odd thing about this 118-meter-diameter island is that it rotates on its own axis in addition to being nearly a perfect circle. Google satellite images make it very simple to see this by allowing users to browse old images.
El Ojo's surface is covered with very solid land, which contrasts with the area around it. The water surrounding this island is also incredibly clear and cold, which is unusual for this region.
“The phenomenon is real and would explain several of the supernatural stories connected with the presence of UFOs in the area and other paranormal aspects”
There are many and various theories about El Ojo, including that it was a Nazi base, a location to hide UFOs, and a simple reservoir. The most common comments are about paranormal phenomena, despite the fact that proponents of science cannot understand the existence of such a thing and are more likely to support the theory of a dammed wetland.
