Steppe Geoglyphs

The Steppe Geoglyphs are a number of Neolithic earth constructions in the Turgai Trough area of Turgai in northern Kazakhstan. There are at least 260 of these earthworks.<ref name=Blumnethal>Template:Cite news</ref><ref>Template:Cite web</ref>

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.<ref name=Blumnethal/> The composite figures range from slightly under 90 m in length to over 400 m in diameter.<ref>[1] Template:Dead link</ref> Besides being made of earth dug out and piled up, some of the geoglyphs are made by placing stones next to each other.<ref>Template:Cite web</ref>

Some of the large shapes have been given names, including Bestamskoe Ring, Ushtogaysky (or Ushtogay) Square, Turgay triradial swastika,<ref>Template:Cite web</ref> Large cross Ashtasti, Ekedyn cross, Ashutasti ring, Kyzyloba line, Koga cross, and Shili square.<ref name=Blumnethal/><ref name=Dey>Template:Cite web</ref>

These shapes are large enough to be easily visible on Google Earth. The Ushtogay Square is at Template:Coord. The Turgay triradial is at Template:Coord, only about half a mile from the town of Urpek. Both are inside Amangeldi District, Kostanay Region.

Discovery and suggested origins

The earthworks were discovered in 2007 by Dimitriy Dey.<ref name=Blumnethal_a>Template:Cite news</ref><ref>Template:Cite web</ref> He found them by searching Google Earth's satellite images for pyramids and similar configurations in Kazakhstan.<ref name="Blumnethal_a"/> They were first reported to the scientific community in 2014.<ref>Template:Cite web</ref>

Optical dating (optically stimulated luminescence) has been used to determine that one of the mounds dates to around 800 B.C.<ref name=Blumnethal/><ref>[2] Template:Dead link</ref> Dey has proposed they were produced by the Mahandzhar culture between seven and nine thousand years ago.<ref>Template:Cite news</ref>
