In 2011, the Swedish diving team known as Ocean X went on an expedition on the northern Baltic Sea, between Sweden and Finland.
There, they took a blurry sonar image of a mysterious rock formation. It showed a remarkably circular rock, 200 feet in diameter and 10 feet thick, balanced on a 26 feet pillar. The stone was found over a staircase-like structure that leads down into a dark hole 300 feet below the ocean's surface.
Some theorize the anomaly could be a leftover anti-submarine device from World War II or a sunken battleship gun turret. Its resemblance to the Star Wars Millennium Falcon led many to believe it could be a crashed UFO. In contrast, others consider it nothing more than a "curious and fun" natural geological phenomenon.
Peter Lindberg, head of Ocean X, said of the anomaly [QUOTE]: "It has these very strange stair formations, and if it is constructed, it must be constructed tens of thousands of years ago before the Ice Age."
Early in 2020, scientists from Stockholm University went underwater to collect samples of the anomaly area. They concluded that the rock formed thousands of years ago, carved by moving glaciers during the Ice Age. Instead of an alien material, the geologists found common rocks, like granites, gneisses, and sandstones.
However, Ocean X doesn't believe the rock is a natural formation. They claim that their electronic equipment, like their satellite phone, stopped working when they got close to the anomaly. Despite the scientific findings, the team believes the rock covers up something bigger, hiding beneath the surface.
In 2019, they performed several low budget expeditions to the area. In them, they found a figure that looked like a monolith, surrounded by rectangle-shaped rocks that appeared to be stone walls. However, they couldn't collect samples or high-resolution images due to disturbances with the compass and sonar when they got close to the rocks. The team concluded that the anomaly does create substantial magnetic deviations, which they will continue to investigate.
