Baltic Sea Anomaly

A sonar image taken by a diving team in the Baltic Sea in 2011 revealed a 60-meter (200 ft) circular rock-like formation with a 300-meter track leading to it at the bottom of the Baltic Sea. The visible non-natural origin promoted speculation that the object was a sunken UFO. Although Swedish explorers generally convinced everyone that it is a rock and not a UFO, their research has raised a lot of questions. Firstly, the rock didn’t have a silt-layer on it, which is usually the case when rocks have been lying still at the bottom of the ocean for any period of time. Furthermore, the rock seems to be covered by construction lines and boxes and it appears to be propped up by a 26 foot (8 m) high pillar.
