In the creation story of the Dreaming, the Rainbow Serpent fashioned the earth and then returned to a spot east of the Kimberleys at a place where the rainbow meets the earth. The Rainbow Serpent's eggs fossilised and became what non-Aborigines now call the Devils Marbles
. The Aborigines know them as Karlukarlu. This collection of huge, round, red-colored boulders is found in the Tennant Creek region of Australia's Northern Territory.
