Wave Rock Earthcache.
Formed more than 2700 million years ago, Wave Rock is 15 metres high, and 110 metres long.
The granite cliff resembling a wave about to break is on the northern face of a large erosional remnant called Hyden Rock.
This curved cliff face is 15 metres high and 110 metres long which has been rounded by weathering and water erosion, undercutting its base and leaving a rounded overhang. It was formed by water dissolving and re-depositing chemicals in the granite as it runs down the cliff face.
The color of the wave:
Tiny lichens, mosses and algae produce the orange and black stains that brighten the face of the wave. Lichens are the result of a symbiotic relationship between algae and a fungus. They are usually the first plant form to colonise granite, and they form the black stains you see on the rock.
The acces to Wave Rock is manage by Hyden Tourism Development Company so please stop at the shop to pay your entry / parking fee.
