The Steppe Geoglyphs are a number of earth constructions in the Turgai Trough area of Turgai in northern Kazakhstan. There are at least 260 of these earthworks.[1][2]
The constructions
Many or all of them consist of smaller earthworks (mounds, trenches, and ramparts) arranged with each other to make geometric and other shapes (composite figures). These shapes are squares, rings, and three others.[1] The composite figures range from slightly under 90 m in length to over 400 m in diameter.[3] Besides being made of earth dug out and piled up, some of the geoglyphs are made by placing stones next to each other.[citation needed]
Some of the large shapes have been given names, including Bestamskoe Ring, Ushtogaysky (or Ushtogay) Square, Turgay triradial swastika,[4] Large cross Ashtasti, Ekedyn cross, Ashutasti ring, Kyzyloba line, Koga cross, and Shili square.[1][5]
The earthworks were discovered in 2007 by Dimitriy Dey.[6][7] He found them by searching Google Earth's satellite images for pyramids and similar configurations in Kazakhstan.[6] They were first reported to the scientific community in 2014.[8]

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.
