Wave Rock is in the wheat belt region of Western Australia, 350 km south-east of Perth. It is a curved granite cliff face, actually the northern face of a large granite erosional remnant called Hyden Rock. This curved cliff face, resembling a wave about to break, is 15 m high and 110 m long. It has been rounded by weathering and water erosion, undercutting its base and leaving a rounded overhang. Water from springs active in the wetter months runs down the cliff face, dissolving and re-depositing chemicals in the granite, leaving red, brown, yellow and grey stains of carbonates and iron hydroxide. Its age has been estimated at about 2700 million years.
