Kazakhstan’s Valley of Balls: Stone Dinosaur Eggs Fallen from the Sky (19 Photos)
Scattered across the vast steppe of Kazakhstan's Mangystau Region, at the foot of Mount Sherkala, lie hundreds of perfectly spherical stone balls. Some are the size of a soccer ball, while others span several meters across. 
The Torysh Valley is a place where geology meets mystery, and every stone holds a secret hundreds of millions of years old.
What Are They, Exactly? 
Geologists refer to these formations as concretions—dense mineral masses that formed deep within sedimentary rock around 120 to 180 million years ago, during the Mesozoic Era. Mineral-rich groundwater gradually crystallized around a central core, such as a grain of sand or an organic fossil, building up layer upon layer until it formed near-perfect spheres. Over centuries, wind and water eroded the softer surrounding rock, exposing these stone giants.
What Makes Them So Unique? 
Moeraki Boulders
Concretions themselves can be found around the globe. Massive spheres adorn New Zealand (the famous Moeraki Boulders, up to 3 meters in diameter), the beaches of Hokianga (where some specimens reach 4 to 6 meters), and several other locations. However, Kazakhstan's Torysh stands out for its sheer scale and concentration. Here, tens of hectares are strewn with giant spherical boulders. Locals call the area Torysh, which translates from Kazakh as "protruding hill." Put more poetically, it is one of those rare places on Earth where nature decided to play a game of giant billiards.
What Is Happening to Them Today? 
In May 2023, Kazakhstan was rocked by a scandal when video footage surfaced on social media showing unidentified individuals casually loading these unique stone spheres onto a truck and hauling them away. Public outrage followed, police tracked down the driver, and the stones were eventually returned. Paradoxically, legal punishment proved impossible because the valley lacks official protected status. Today, Torysh remains one of Mangystau’s top natural attractions, actively promoted as a travel destination (even earning a feature in The Washington Post). Yet the challenge of preserving these unique concretions remains unresolved.
