Wave Rock In Australia

Wave Rock is an interesting natural rock formation located east of the small town of Hyden in Western Australia. It derives its name from the fact that it is shaped like a tall breaking ocean wave. The Wave Rock is composed of granite and the total outcrop covers several hectares.

 

 

Wave Rock, more than 2.7 billion years old, is composed of granite and has been shaped by chemical weathering. The total outcrop covers several hectares and is part of the Hyden Rock erosional remnant. The "wave" part of the rock is about 14 m (47 ft) high and around 110 m (350 ft) long.

 

 

The 'wave' formation was formed 60 million years ago by subsurface chemical weathering followed by removal of the soft weathered granite by fluvial erosion, thus the weathering occurred below ground level before it was exposed. The end result is an undercut base, leaving a round overhang.
