A new archeological discovery leads to questions of when the Australian continent was first visited by westerners. The Djulirri rock cave depicts a history of western vehicles from boats to cars to planes to bicycles. The earliest sailing ships depicted has researchers theorizing the continent was visited by outsiders long before the British arrived.
The history on the rock includes details of ship interiors and interactions with visitors, as well as more characteristic drawings of animals of the desert. This narrated slideshow is a must see.
The aboriginal elder who first led researchers to the site is hoping to protect the site with an "indigenous ranger program," which would oversee care of the site. The expectation of increased tourism to the area is well-founded, and the hope is to prevent degredation by tourist traffic. Protection of the site may include the need to stave off plutonium and uranium extraction in the surrounding mountain range.
