[2] The wall and dam were constructed in December 1928 by the Public Works Department for the colonist settlers of East Karlgarin District.
They respected this area as an icon of cultural learning; a moral from this Dreamtime tale was to be remembered for life.
[5][6] The rock is part of a dreaming trail that extends from the south coast near Augusta to the Great Victoria Desert country to the north east.
The initial step in the development of Hyden Rock was the subsurface alteration by weathering of granite bedrock beneath a lateritised land surface during the Cretaceous Period between 100 and 130 million years ago.
Following separation of Australia and Antarctica and accompanying tilting of what became southwestern Australia, periodic erosion of the deeply weathered granite, which underlaid the surrounding land surface, exposed these buried solid bedrock domes over time as Hyden Rock.
Flared slopes like Wave Rock are particularly well developed in granitic landforms of south-western and southern Australia.
The flared slopes are argued to have formed by the concentrated chemical weathering around the base of an inselberg by groundwater.
