Discovered using Google Earth, the geoglyphs are designed...
Spotted on Google Earth in 2007 by a Kazakh economist and archaeology enthusiast, Dmitriy Dey, the so-called Steppe Geoglyphs remain deeply puzzling and largely unknown to the outside world.
Since then, Dey has found about 260 of the land designs—which resemble crop circles, but are much stranger.
Dey's research suggests that the figures could have been constructed by the Mahandzhar culture, who thrived in the vast steppes of what is now northern Kazakhstan between 5,000 and 7,000 B.C.
