This is a new one for me.
Found in the Antarctic in 13,500 feet of water, take a look at it's design.
In 1964, the National Science Foundation Polar Research Vessel Eltanin photographed an unusual object at a depth of 13,500 below the south Atlantic. It appeared to be some sort of antenna rising from the sea floor. Although it was dismissed as a 'marine organism,' it does not appear to be a natural object. The central pole has spokes radiating from it at fifteen degree angles from each other, with spheres on the end. A small structure caps the vertical pole of the object.

Strangely, earthquake stations and antarctic bases have been built in a regular pattern around this object. And yet, we had no vessel capable of reaching a depth of 13,500 feet in 1964, so it is hard to see how the object could have been placed there by any known means. And if it is a classified object, why did the officers of the Eltanin even release the photo?
