El Ojo: Argentina's Enigmatic Floating Eye Island

El Ojo is a mysterious, perfectly round floating island located in the Paraná Delta of Buenos Aires Province, Argentina. Discovered by filmmakers in 2016, the island is made of plant matter and floats in a crystal-clear, circular lake, rotating due to a circular current. Its origins are unclear, and it has sparked local myths, including beliefs about ancient deities and UFOs. The island's unique formation is attributed to erosion, similar to ice disks observed in Maine, USA.
