The Marree Man [wiki] is 4.2 km tall figure of a guy throwing a stick carved into the earth of South Australia. It was spotted by a charter pilot from the air in 1998.
The lines of the figure was made with a plough attached to a tractor, but no one knows who made it or why. Perhaps the maker just wanted to make the largest manmade artwork in the world.

Curved stick? don't you mean a boomerang?

Wonder if the inspiration was the Nazca Lines...

The lines made with a plough attached to a tractor? I wonder if lines could be made with such precision using a plough. It would seem that a traced pattern would have had to have been laid down first - I don't know if there is much stone and brush in the way but that would have had to have been cleared too. This would seem to have been quite a lot of work, for a team of several persons.
