This feature is called The Devils Marbles. The “Marbles” have been formed over millions of years by the act of erosion and rise up out of the desert scenery in a surreal display of granite – kind of like a natural art exhibition. Each boulder comes in a different size, ranging from between 50 centimetres to six metres across. Perhaps the most amazing part of the scene is that many of the huge stones are balanced on top of each other, seeming to defy gravity. Even today, they are continuously evolving in a constant stream of cracking and erosion.
