First of all, its origin – a question that still baffles scientists. There have been theories from nuclear blasts to secret gulags to even the far-fetched alien involvement. At first, it was believed to be the result of a meteorite strike with the meteor sinking underground. A theory was put forward to link it with the impact of the Tunguska meteorite, whose remains were never found. But no evidence of meteoric fragments has ever been found. Some believe it could be a nascent volcano, but the area is completely free of any volcanic or asteroid residue. In fact, there are no volcanoes for thousands of kilometers around and the crater seems to be relatively new as well.After studying the growth ring of the trees growing on it, scientists have estimated its age to be anywhere around 300-350 years old. However, scientists also noticed one peculiar quality about the old trees growing here. 

Located near the northeastern edge of Argentina, in the swampy marshes of Parana Delta, is an enigmatic floating island that allegedly rotates on its own axis. Nicknamed “The Eye”, the nearly perfect circular island has become the subject of an upcoming documentary that will try to unravel the mystery of its existence.

The Eye was discovered six months ago by Argentine film director & producer Sergio Neuspillerm, who was looking for filming locations for a film about paranormal occurrences, like ghost and alien sightings, in the area. After spotting the unusually round island surrounded by an equally round body of water on Google Earth, Neuspillerm and his crew knew they had stumbled upon something truly special, so they abandoned their original film project and decided to focus on this mystery instead.

“When locating this reference in the map we discovered something unexpected that left the film project in the background, we call it ‘The Eye’,” Neuspillerm said in a video. “The Eye is a circle of land surrounded by a thin channel of water with a diameter of 130 yards. Both circles [the water and land] are so perfect that it is hard to believe that this is a natural formation.”
