This photo was taken at the Devils Marbles Conservation Reserve (see official website), located south of Tennant Creek area of Northern Territory in Australia. The site is known as Karlu Karlu to the land's Aboriginal traditional owners. The ‘Devil’s Marbles’ or ‘Karlu Karlu’ with its gigantic, rounded granite boulders, some spectacularly poised, is a remarkable landscape. Scattered clusters of these ‘marbles’ are spread across a wide, shallow valley. The Devil’s Marbles is a nationally and internationally recognised symbol of Australia’s outback.
