The valley of balls or Torysh, as it's called in Kazakh, is located close to the town of Shetpe in Western Kazakhstan. The area consist of numerous ball-like rock formations strewn across a wide range of steppe land.
The balls are believed to be concretions - a hard, compact mass formed by the precipitation of minerals. The phenomenon is not rare. What is rare, however, is the size these concretions have reached. Concretions as large as those in the Valley of Balls are found only at few places on earth.
