Tennant Creek - Devils Marbles

The Devils Marbles near Tennant Creek, known as Karlu Karlu by the local Warumungu Aboriginals,are a collection of huge, red, rounded granite boulders scattered across a wide,shallow valley. The boulders formed millions of years ago when an upsurge of molten rock reached the surface and spread out in a solid layer. Erosion over millions of years, caused the large block of erupted granite to crack and split into rectangular blocks, progressing to erode the sharp corners to smooth and finally rounded edges . Many of the giant boulders are precariously balanced on top of one another. The area surrounding the boulders is somewhat flat which makes this huge rounded collection even more spectacular.Read more
