A pilot discovered the mysterious 2.6-mile-long geoglyph of an aboriginal hunter in 1998, etched into the earth, and to this day no one knows how it got there.

The Marree Man gained new life in 2016 when a group from the figure's namesake town of Marree plowed the lines to keep the man from fading due to erosion. Now, NASA is sharing an image taken in June showing the success of their efforts.

Many have tried to discover the origin of the Marree Man.

He believed it was professionally done, so in 2018 he offered a reward of $5,000 Australian dollars ($3,712) for anyone with information regarding its existence.

No one has come forward, but several believe it was made by an artist living in Alice Springs, though other clues suggest the creator may have been an American.

Regardless, the Marree Man mystery lives on.
