Could a formation like
The aim is not to present this particular formation as man-made, but to examine whether a design with the above features could be created by a group of people.
Those figures seem mind-blowing. One should not be surprised if anybody's first guess was this could not be accomplished without supernatural forces. But the first guess might not be that reliable after all..
I started by making a contrast enhanced image of an aerial photo
(see above). This shows the flattened area as black against a white
backround. I then cropped the image as tightly as I could and scaled
it to a size of only one pixel in Adobe Photoshop. This was a way
to get the average darkness of the image, the result being 31%. In
other words, 31% percent of the 90.000 square meters (300 x 300) area
is flattened. Let's round it up to 33,3%, that is one third of 90.000,
giving us 30.000 square meters to flatten (of course flattening
is only one part of the whole process).
