How Wave Rock was Formed
Wave Rock is a granite formation that is 15m high and 110 m long. The oldest rocks found in Wave Rock are dated back to over 3000 million years ago. That makes it one of the oldest rocks in the world. It's rounded shape has been caused by weather and erosion over the course of 60 million years. In winter, when it is raining, the droplets of rain shape the rock even more. The colours have been formed by minerals washing down the surface of the rock in the wet season.
