 According to the legends of the Kabi people, the dunes were coloured when Yiningie, a spirit represented by a rainbow, plunged into the cliffs after doing battle with an evil tribesman.Much of the sand colours stem from the rich content of minerals in the sand, such as rutile, ilmenite, zircon, and monazite.A black dune of ilmenite sands, overgrown by dune vegetation, can be found north west of the main town.
