The Australian Wave Rock is a series of rocks in Australia that appear to be waves, made completely out of rocks.
Why Is It Famous?
The unique wave-like appearance of the rocks makes this landmark famous. The formation is the same shape of a tall ocean wave that is breaking, yet it is solid rock.
The Wave Rock also holds Ballardong cultural significance. Tribes believed the Rainbow Serpent created the rock when she dragged her body over land after consuming all the water there.
The Wave Rock is around three kilometers east of Hyden, a small town. The formation is about 296 kilometers to the east-southeast of Perth in Western Australia. Both Hyden Rock and Wave Rock are in the Hyden Wildlife Park, which is a 160-hectare nature preserve.
The Wave Rock measures around 15 meters tall and is about 110 meters long. It sits on the northern side of Hyden Rock, a hill that is a granite inselberg. Wave Rock is part of Hyden Rock, the latter of which includes a 2.63-billion-year-old rock. This rock is biotite K-feldspar porphyritic monzogranite from the Yilgarn Craton.
The granite inselberg that is Hyden Rock includes three domes. A deep valley that acts as a reservoir separates the western and central domes. A low platform connects the eastern and central domes. Those domes were created via multi-stage landform development that involved weathering granite bedrock in the Cretaceous Period. The Wave Rock is a classic flared slope in geomorphology.
Events in Time
There is a wall halfway up on Hyden Rock and above Wave Rock. This wall follows the rock wall’s contours, collecting and funneling water into a storage dam. The Public Works Department of East Kalgarin District created the dam and wall in December 1928, with renovations in 1951 for a larger capacity.
The Australian Wave Rock got its name for its wave-like appearance and is a geological flared slope that has played a role in local legends.
