- Using satellite imagery, NASA recently documented a series of geoglyphs in a remote region of central Kazakhstan. What are geoglyphs?
- A geoglyph is a large design (glyph) produced on the ground from earthen (geo-) materials, such as dirt and rocks.
- The Turgai geoglyphs are positive geoglyphs. This means their creators used earthen materials to build up the glyph. Negative geoglyphs are produced by removing earthen materials to carve channels or canals.

- Where else on Earth can you find ancient geoglyphs?
- All over!
- The most famous geoglyphs in the world are probably the lovely Nazca Lines in Peru. The Nazca Lines, which include both positive and negative geoglyphs, were created between 500 BCE and 500 CE.
- The Uffington White Horse is a negative geoglyph cut into the white chalk hills of Oxfordshire, England. The beautiful Uffington White Horse was created between 1000 BCE and 700 CE.
- Native Americans in what is now Effigy Mounds National Monument, Iowa, created enormous positive geoglyphs in the shape of bears, birds, turtles, and panthers. The moundbuilding cultures associated with the geoglyphs of Iowa and Wisconsin flourished between 615 and 1250.
- Wheel-shaped positive geoglyphs dot the Middle East from Syria to Saudi Arabia. These stone structures were created around 2,000 years ago. (About 15 CE? That’s later than I would have thought.)
- Deforestation has revealed positive geoglyphs in the Amazon basin. These pre-Columbian geoglyphs were created between 1,000 and 2,000 years ago.
- A giant elk simply known as the “Russian geoglyph” was discovered in the meteor-prone Chelyabinsk region 2011. The positive Russian geoglyph was created between 4000 BCE and 2000 BCE.
- The Blythe intaglios of people and animals are part of the desert landscape near my hometown of Blythe, California. The negative geoglyphs were created between 900 BCE and 1200 CE.
- All over!
- If ancient geoglyphs are so common, why are archaeologists so surprised by the Turgai geoglyphs of Kazakhstan? Read through the New York Times article for some help.
- They’re old! Some “preliminary studies push the earliest date back more than 8,000 years, which could make them the oldest such creations ever found.” (To be fair, other studies date the structures to less than a thousand years ago.)
- They’re complex! The Turgai geoglyphs seem to be associated with the Mahandzhar, a nomadic culture that flourished in the region between 7000 BCE and 5000 BCE. The organization required to build such large-scale engineering projects is usually not associated with nomadic cultures. “The idea that foragers could amass the numbers of people necessary to undertake large-scale projects—like creating the Kazakhstan geoglyphs—has caused archaeologists to deeply rethink the nature and timing of sophisticated large-scale human organization as one that predates settled and civilized societies,” says one archaeologist.
- What were the Turgai geoglyphs used for?
- To be determined. One archaeologist makes an educated guess that the geoglyphs were “horizontal observatories to track the movements of the rising sun.”
- It’s important to note what the Turgai geoglyphs are not: burial mounds. No trade goods or genetic material has been identified in the Turgai geoglyphs.
- The Turgai geoglyphs are also called the “steppe geoglyphs.” Why? Read through our short encyclopedic entry on steppes for some help.
- A steppe landscape describes a dry, grassy plain. The largest temperate grassland in the world is the Eurasian steppe, extending from Hungary to China. The Eurasian steppe is so well-known, the area is sometimes referred to as just The Steppe. The Turgai geoglyphs are right in the middle of the Eurasian steppe.
