Believed to have formed over 2700 million years ago, Wave Rock is part of the northern face of Hyden Rock. The shape of the wave is formed by gradual erosion of the softer rock beneath the upper edge, over many centuries. The colours of the Wave are caused by the rain washing chemical deposits (carbonates and iron hydroxide) down the face, forming vertical stripes of greys reds and yellows.
