Al Wathba, Abu Dhabi (CNN) — Drive an hour or so southeast out of town of Abu Dhabi toward the emirate’s empty deserts and likewise you’re going to hit a landscape beefy of sudden man-made creations.
The realm of Al Wathba is home to a safe oasis-care for wetland reserve created, so the anecdote goes, by an overspill from a water therapy facility. Now or now now not it is a lush terrain that attracts flocks of migratory flamingos.
Farther along roads lined with reasonably planted trees, there’s the surreal location of an artificial mountain rising up on the horizon, its flanks buttressed by enormous concrete walls.
And stray off the principle roads onto the lend a hand lanes, you’re going to stumble upon wide and dusty camel highways, where cooler evening temperatures leer immense fleets of the humped beasts being exercised in readiness for the cool weather racing season.
But no doubt one of Al Wathba’s more irregular and neat sights is now now not the work of folks. As a change or now now not it has been crafted over tens of hundreds of years by elemental forces that, despite the actual fact that they had been at play millennia within the past, supply insight into how the original local weather crisis would possibly possibly reshape our world.
Abu Dhabi’s fossil dunes stand up out of the surrounding desolate tract care for frozen waves in a violent ocean fabricated from solid sand, their facets rippling with shapes outlined by raging winds.
‘Advanced anecdote’

Though these proud geological relics have survived for hundreds of years out within the course of nowhere, they had been opened as a free tourist appeal in Abu Dhabi in 2022 as portion of efforts by the emirate’s Ambiance Agency to defend them internal a protected location.
Whereas Instagrammers and utterly different traffic as soon as the largest all-terrain autos to maneuver as much as the fossil dunes trying to safe a dramatic selfie backdrop, they now win a possibility of two broad parking a lot that bookend a path which meanders previous a few of the more spectacular landmarks.
Alongside the formula are informative signposts that give some bare-bones recordsdata on the science within the lend a hand of the dunes’ advent — if truth be told, moisture within the bottom introduced about calcium carbonate within the sand to harden, then noteworthy winds scraped them into irregular shapes over time.
But there’s scheme more to it than that, says Thomas Steuber, a professor within the Earth Science Division of Abu Dhabi’s Khalifa University of Science and Abilities, who spent worthy of the Covid lockdown discovering out the dunes while unable to scurry to totally different areas of geological curiosity.
“It be a slightly advanced anecdote,” Steuber tells CNN.
The dunes are a stone’s throw a long way flung from a Wetland Reserve, Abu Dhabi’s first protected location.
Steuber says that generations of dunes had been created by cycles of ice ages and thaws that happened between 200,000 and 7,000 years within the past. Ocean levels dropped when frozen water increased on the polar caps and all over these drier sessions, dunes would’ve built up as sand blew in from the drained Arabian Gulf.
When the ice melted, resulting in a more humid ambiance, 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 have a more or less cement, which used to be later whipped into ethereal shapes by prevailing winds.
Harmful forces

“The Arabian Gulf is a tiny basin that is highly shallow,” says Steuber. “It be fully about 120 meters deep, so on the peak of the ice age, about 20,000 years within the past, there used to be so worthy piled up on the polar ice caps that water used to be lacking from the ocean. That intended the Gulf used to be dry and used to be the provision of field materials for the fossil dunes.”
Steuber says that the fossil dunes, which occur at some level of the UAE and would possibly possibly possibly additionally be order in India, Saudi Arabia and the Bahamas, likely took hundreds of years to have. But, despite the kindly safety now equipped in Abu Dhabi, the erosion that gave every its consuming shape will additionally within the waste lead to their loss of life.
“About a of them are rather broad, however within the live the wind will execute them. They are if truth be told rocks, however that you would possibly possibly additionally every so regularly damage them along with your hands. It be rather a feeble field materials.”
Which is why, at Al Wathba, traffic are in actuality being kept a ways from the dunes, even if aloof terminate sufficient to care for their impassive elegance.
Touring the location is easiest in early evening when harsh daylight light is replaced by a golden glow from the setting solar and the sky takes on the lilac hues of magic hour. It takes about an hour to stroll along the sandy course from the visitor center and memento stall to the car car car car parking zone on the a couple of live — and about 10 minutes to shortcut lend a hand.
The untouched serenity of the dunes is contrasted at some facets along the path by a series of enormous red and white electricity pylons that toddle over the horizon within the distance. In possibility to spoil the scene, this engineering spectacle provides a dramatic popular dimension to a landscape otherwise frozen in time.
As dusk settles, a few of the dunes are illuminated, offering a brand unique formula to gape these geological marvels.

“The dunes seek for in actuality fabulous,” stated Dean Davis, visiting the location all over a damage day from work in Abu Dhabi city. “It be tremendous they’re being conserved and the federal government has completed an infinite job.”
Ashar Hafeed, one other visitor touring along with his family, stated he used to be additionally impressed. “I noticed it on Google and factual the largest to approach and rob a peek,” he stated, adding that “as soon as used to be sufficient” to care for the dunes.
Stauber and his crew from Khalifa University are liable to be repeat traffic despite the actual fact that.
“We’re persevering with to leer them,” he says. “There are loads of keen questions about sea-level changes all around the fresh ice ages aloof to acknowledge to and or now now not it is the largest for figuring out the original geomorphology of the coastline of the Emirates. It be additionally clearly an analog for future sea-level change.”
And, says Steuber, the dunes would be evidence of the inspiration within the lend a hand of the chronicle of Noah’s flood, which facets within the Koran, the Bible and the Torah, the texts of the three notable religions to emerge from the Heart East.
“Perchance, this used to be the flooding of the Arabian Gulf on the live of the ice ages, since the sea level upward thrust used to be very fleet.
“With a dry Arabian Gulf, the Tigris and Euphrates rivers would’ve discharged into the Indian Ocean and what’s now the Gulf would had been rather a fertile low lying location which 8,000 years within the past would’ve been inhabited, and of us can even have skilled this fleet sea level upward thrust.
“Perchance it led to some historic memory that made the holy books of these three local religions.”
