The Devils Marbles Conservation Reserve contains formations of naturally rounded and oval boulders called Karlu Karlu by the local Aborigines. The area is located near Wauchope, 114km south of Tennant Creek in Australia's Northern Territory. The boulders are located in a traditional Aboriginal sacred site and are important to the local Aboriginal people. The Kaytetye people believe that the boulders are the eggs of the rainbow serpent.
