Mysterious Marree Man

1998 Australia: Trec Smith, a charter pilot flying between Marree and Coober Pedy in the remote north of South Australia, discovered Marree Man, which is both the world's largest known geoglyph, and the world's largest known work of art.

The geoglyph appears to depict an Indigenous Australian man, most likely of the Pitjantjatjara tribe, hunting with a throwing stick. The figure is 4.2 kilometres long, with a circumference of 15-28 km. The image was made in modern times, by an unknown person, or persons, using a tractor.
