I have to ask. Are these with out a doubt man made megaliths? Could they not be natural stone formations?

Natural formations that look like stone bricks is possible. America Unearth series has a town in TX that was surrounded by a 8 story “wall”. Unearthed it looked like man laid rectangular stones. The expert drilled stone samples and had it analyzed for low magnetic orientation. If it is a natural formation, all the samples stone magnetic orientation will point in one direction. If manmade, all the sample magnetic orientation will be random. It turned out that millions of years ago, area in TX was under water and lava pressured earth upward to form a wall like bathtub. Upon cooling it formed cracks that give a visual impression of man laid rectangular blocks. These formations are rare but possible.

My feeling, too, is that these are natural formations. They don’t “look like” anything and they seem to be granite, a very hard rock to shape. Some natural formations have surprisingly square forms because they break/erode along natural cracks which in some cases tend to be very straight lines. The “Giant’s Causeway” in Great Britain (I think it is) is a wonderful example of something that looks manmade, but is not.
