Etched into the dry sand of Australia’s barren outback is the world’s largest geoglyph, known as “Marree Man,” an enormous figure of an Aboriginal man hunting birds or wallabies with a throwing stick.
Unlike other anthropomorphic geoglyphs found around the world, which were constructed by ancient civilizations, Marree Man was carved into the landscape only 16 years ago. However, its very existence presents one of the greatest mysteries Australia has ever seen; the geoglyph is so large that it is viewable from space, yet not a single witness can attest to its creation and to this day, its creator and the reason for its construction remain unknown.
The Marree Man geoglyph lies on a plateau of arid land, approximately 60 kilometers (37 miles) west of the tiny township of Marree (population = 60) in South Australia. Trevor Wright, a charter pilot, was flying between the townships of Marree and Coober Pedy on June 26, 1998, when he spotted the towering figure in the landscape below.
The figure is 4.2 kilometers (2.6 miles) tall with a perimeter of 15 by 28 kilometers (9.3 by 17.4 miles). At the time of discovery, the outline was 30 centimeters (12 inches) deep and up to 35 meters (114 feet) wide.
Surveyors speculate that the figure was made by bulldozer and could have taken weeks to complete, yet no one claims to have seen or heard a thing. Only one track led into and out of the site, but no footprints or tire marks were discernible, and a thorough police investigation conducted at the time came up with nothing.
