Al Wathba, Abu Dhabi (CNN) — Force an hour or so southeast out of the town of Abu Dhabi towards the emirate’s empty deserts and you’ll be able to hit a panorama filled with sudden man-made creations.
The area of Al Wathba is house to a lovely oasis-like wetland reserve created, so the tale is going, through an overspill from a water remedy facility. Now it is a lush terrain that pulls flocks of migratory flamingos.
Farther alongside roads coated with in moderation planted timber, there is the surreal web site of a man-made mountain emerging up at the horizon, its flanks buttressed through gigantic concrete partitions.
And stray off the principle roads onto the again lanes, you’ll be able to stumble upon broad and dusty camel highways, the place cooler night temperatures see huge fleets of the humped beasts being exercised in readiness for the iciness racing season.
However one in every of Al Wathba’s extra atypical and stylish sights isn’t the paintings of people. As an alternative it is been crafted over tens of hundreds of years through elemental forces that, despite the fact that they had been at play millennia in the past, be offering perception into how the present local weather disaster may reshape our international.
Abu Dhabi’s fossil dunes stand up out of the encompassing desolate tract like frozen waves in a violent ocean product of cast sand, their facets rippling with shapes outlined through raging winds.
‘Advanced tale’

Despite the fact that those proud geological relics have survived for hundreds of years out in the course of nowhere, they had been opened as a unfastened vacationer appeal in Abu Dhabi in 2022 as a part of efforts through the emirate’s Setting Company to keep them inside a secure house.
While Instagrammers and different guests as soon as wanted all-terrain automobiles to journey as much as the fossil dunes looking for a dramatic selfie backdrop, they now get a selection of two massive parking loads that bookend a path which meanders previous one of the vital extra impressive landmarks.
Alongside the best way are informative signposts that give some bare-bones data at the science in the back of the dunes’ advent — necessarily, moisture within the floor brought about calcium carbonate within the sand to harden, then tough winds scraped them into atypical shapes over the years.
However there is way more to it than that, says Thomas Steuber, a professor within the Earth Science Division of Abu Dhabi’s Khalifa College of Science and Generation, who spent a lot of the Covid lockdown learning the dunes whilst not able to go back and forth to different spaces of geological passion.
“It is a lovely advanced tale,” Steuber tells CNN.
The dunes are a stone’s throw clear of a Wetland Reserve, Abu Dhabi’s first secure house.
Steuber says that generations of dunes had been created through cycles of ice ages and thaws that came about between 200,000 and seven,000 years in the past. Ocean ranges dropped when frozen water greater on the polar caps and all through those drier classes, dunes would’ve constructed up as sand blew in from the tired Arabian Gulf.
When the ice melted, resulting in a extra humid atmosphere, the water desk rose in what’s now Abu Dhabi and the moisture reacted with the calcium carbonate within the sand to stabilize it after which shape a type of cement, which used to be later whipped into airy shapes through prevailing winds.

“The Arabian Gulf is a small basin that is very shallow,” says Steuber. “It is just about 120 meters deep, so on the height of the ice age, about 20,000 years in the past, there used to be such a lot piled up at the polar ice caps that water used to be lacking from the sea. That supposed the Gulf used to be dry and used to be the supply of subject material for the fossil dunes.”
Steuber says that the fossil dunes, which take place all through the UAE and can be present in India, Saudi Arabia and the Bahamas, most likely took hundreds of years to shape. However, in spite of the legitimate coverage now presented in Abu Dhabi, the erosion that gave every its distinctive form may also ultimately result in their loss of life.
“A few of them are slightly huge, however finally the wind will damage them. They’re necessarily rocks, however you’ll be able to once in a while spoil them along with your fingers. It is slightly a susceptible subject material.”
Which is why, at Al Wathba, guests at the moment are being stored far from the dunes, even though nonetheless shut sufficient to realize their emotionless good looks.
Traveling the web site is best possible in early night when harsh daylight hours gentle is changed through a golden glow from the environment solar and the sky takes at the lilac hues of magic hour. It takes about an hour to walk alongside the sandy trail from the customer heart and memento stall to the parking space on the different finish — and about 10 mins to shortcut again.
The untouched serenity of the dunes is contrasted at some issues alongside the path through a series of gigantic crimson and white electrical energy pylons that stride over the horizon within the distance. Slightly than damage the scene, this engineering spectacle provides a dramatic fashionable measurement to a panorama differently frozen in time.
As nightfall settles, one of the vital dunes are illuminated, providing a brand new approach to view those geological marvels.

“The dunes glance in reality superb,” stated Dean Davis, visiting the web site all through a time without work from paintings in Abu Dhabi town. “It is great they are being conserved and the federal government has accomplished a really perfect task.”
Ashar Hafeed, every other customer traveling together with his circle of relatives, stated he used to be additionally inspired. “I noticed it on Google and simply had to come and have a look,” he stated, including that “as soon as used to be sufficient” to realize the dunes.
Stauber and his workforce from Khalifa College usually are repeat guests despite the fact that.
“We are proceeding to check them,” he says. “There are slightly a couple of attention-grabbing questions on sea-level adjustments all through the new ice ages nonetheless to respond to and it is crucial for figuring out the present geomorphology of the beach of the Emirates. It is usually clearly an analog for long term sea-level alternate.”
And, says Steuber, the dunes may well be proof of the foundation in the back of the story of Noah’s flood, which options within the Koran, the Bible and the Torah, the texts of the 3 primary religions to emerge from the Center East.
“In all probability, this used to be the flooding of the Arabian Gulf on the finish of the ice ages, for the reason that sea point upward thrust used to be very fast.
“With a dry Arabian Gulf, the Tigris and Euphrates rivers would’ve discharged into the Indian Ocean and what’s now the Gulf would were slightly a fertile low mendacity house which 8,000 years in the past would’ve been inhabited, and other folks can have skilled this fast sea point upward thrust.
“In all probability it led to a few ancient reminiscence that made the holy books of those 3 native religions.”
