An ancient “super-megalithic” site has been found in the Siberian Mountains.  Found recently in Gornaya Shoria (Mount Shoria) in southern Siberia, this site consists of huge blocks of stone, which appear to be granite, with flat surfaces, right angles, and sharp corners.  The blocks appear to be stacked, almost in the manner of cyclopean masonry, and well…they’re enormous!
Some of the gigantic granite stones are estimated to weigh 3,000 to 4,000 tons.
