Marree Man | Giant Outback Figure

The mysterious Marree Man is a four kilometre-long carving etched deep into the red earth of Outback South Australia.

After being discovered in 1998, still no one knows who created it or why.

Located 65 kilometres away from the town of Marree, you can see the man himself on a scenic flight from the historic Marree Hotel or with Wrightsair.

First discovered on 26th June 1998, the Marree Man, over time, eroded to almost 'extinction'.

Nobody knows who is responsible for the giant in the outback.

Marree Man

Since a pilot first noticed Marree Man in 1998, the mysterious work of earthen art has attracted international attention. Etched into a plateau in South Australia, the artwork depicts a hunter with what appears to be a stick or boomerang in his hand.

Spanning 3.5 kilometers (2.2 miles) from top to bottom, Marree Man is a geoglyph—a design made from earthen materials that is so large it is best viewed from above. An example of an even larger geoglyph is the Nazca Lines in Peru.

For many years, Marree Man, named after a nearby town, was a prominent feature in Landsat satellite images of the area, but the lines faded over the years. By 2013, they were hardly visible in the natural-color images acquired by the Operational Land Imager (OLI) on Landsat 8.

In August 2016, local business owners, concerned about the loss of what had become a tourist draw, decided to restore the fading geoglyph. With accurate GPS coordinates for the original in hand, they used a construction grader to redraw Marree Man over a period of five days.

The restoration team thinks the updated geoglyph will last longer than the original because they created wind grooves, designed to trap water and encourage the growth of vegetation. Over time, they hope vegetation will turn the lines green. The OLI acquired this image of the feature on June 22, 2019.

Who created the geoglyph and why has long been a topic of controversy and remains unknown, despite the recent announcement of a cash reward for credible information about it. There are indications that an artist living in Alice Springs may have created Marree Man, though other clues suggest that the creator may have been an American.

Marree Man: The enduring mystery of a giant outback figure

This week marks 20 years since a helicopter pilot flying over central Australia spotted the outline of a giant man drawn into the earth.

The 4.2km (2.5 miles) tall figure, on a remote plateau in South Australia, is often thought to depict an Aboriginal hunter.

Dubbed Marree Man after a nearby town, it is one of the world's largest designs to be etched into the ground.

But mystery surrounds who created it - and why.

Earlier this week, Australian entrepreneur Dick Smith offered a A$5,000 (£2,800; $3,700) reward for any information about the artwork's origins.

"How has it been kept secret for 20 years?" he said on the Australian Broadcasting Corporation (ABC) on Monday.

'Professionally done'
Marree Man has been a subject of fascination since its discovery in the desert about 700km north of Adelaide.

It has gained popularity on tourism flights because it is too large to be viewed from the ground.

With an outline measuring a total of 28km, Marree Man had an initial depth of about 35cm (14 inches), according to local media reports.

Locals believe it portrays an Aboriginal man carrying a woomera - a throwing stick - in his left hand.

Marree publican Phil Turner says he is convinced that its creator, or creators, were "professionals" who possibly used GPS technology.

"Whoever did the outline marked it out with bamboo nursery skewers at every 10m," Mr Turner told the BBC.

"If you didn't have the co-ordinates, you would have no idea if you were standing in his left toe or his elbow. Considering GPS technology was in its infancy at the time, it is an absolutely remarkable feat."

Mr Smith agrees, telling the ABC: "There were no mistakes - it was very professionally done."

Several theories about its creators have circulated over the years.

Pilot Trevor Wright, the first to see Marree Man on 26 June 1998, says he spotted it by chance. But anonymous faxes were also sent to local businesses and media at the time, to inform them of Marree Man's existence.

Some suspected it was the work of American artists because the faxes used US spelling and references. A plaque showing the US flag and Olympic rings was also found at the site.

But others have theorised that those clues were deliberately misleading, with alternative suggestions including local artists and even members of the Australian Army.

'Mix of opinions'
The Arabana people are the traditional owners of the land on which Marree Man was created.

Arabana Aboriginal Corporation manager Lorraine Merrick said its appearance in 1998 had initially upset some Aboriginal people who viewed it as a desecration of their land.

She said there was "a mix of opinions now".

However, Ms Merrick said the corporation - which administers the land - recognised that Marree Man had become an icon.

"It's there now and you can't turn back the clock," she told the BBC. "So for us it's about working out a clear strategy for its future."

Marree Man has faded over the years, but locals, with the approval of the Arabana people, used machinery to help to restore it in 2016.

"Maybe the mystery is part of its attraction, but honestly I don't have people coming up to me asking who did it or anything like that," Ms Merrick said.
