For 1,100 kilometers between South Australia and Western Australia, the Nullarbor Plain stretches flat and almost featureless beneath a sky so wide it bends at the edges. This is the world's largest single exposure of limestone bedrock, roughly 200,000 square kilometers of ancient seabed lifted into the sunlight during the Miocene, somewhere between 15 and 5 million years ago. The Mirning clans and Yinyila people knew this country long before Latin provided its name. They called it Oondiri -- the waterless -- and their seasonal occupation of its vast reaches speaks to an intimate knowledge of a landscape that Europeans would spend decades trying merely to cross.

Nullarbor Plain: Life at the Edge of Nothing
