Of course, there is much conjecture as to the origins of the giant geoglyph. Some say that American servicemen based at the Australian Space Research Institute at Woomera created it, to leave a lasting memento of their time in Australia. Others believe that workers from the Olympic Dam mine at nearby Roxby Downs were responsible; they certainly would have had access to the heavy earthmoving equipment, but why? A couple travelling along the Oodnadatta Track at the time later reported having seen a unit of three Australian Defence Force vehicles, one of them carrying a bulldozer, but the ADF insists that none of their personnel were within 200 kilometres of the figure during the time it was being made.
