The black cliffs of Djibouti in the Horn of Africa may seem featureless at the first sight from afar. However, the rocks reveal 7,000-year-old engravings depicting various figures, from giraffes to antelopes, that offer insight into the past of the region.
These masterful works, etched onto the stone in northern Djibouti, are among the most important examples of rock art in the Horn of Africa, a region rich in archaeological heritage and the birthplace of humanity.
Stretching three kilometers (almost two miles), some 900 panels at Abourma depict in wonderful relief prehistoric life in these parts, dramatic scenes of early man confronting wildlife, and droving cows.
But these centuries-old images, rendered by flint onto igneous rock, also offer a valuable record of a bygone era and a land drastically reshaped by millennia of climate change.
The wildlife illustrated are still found today on Africa's plains and grasslands, but not in Djibouti, a harsh desert landscape where water and greenery have been scarce for thousands of years.
"Today, Abourma is something of a cemetery because we don't have these animals here anymore. At the time, they roamed here because Djibouti was covered in forest," said Omar Mohamed Kamil, a young tour guide who takes visitors to Abourma.
"In Abourma ... we are a little removed from civilization. We are in the prehistory, we are living in prehistory."
Millennia upon millenniaDespite this local wisdom – and roughly 70 centuries of existence – Abourma was not visited by archaeologists until 2005.
This treasure-trove lies a six-hour drive away from the capital, Djibouti City, then a further one hour on foot over a craggy expanse of boulders.
It would be all-but-impossible to find were it not for Ibrahim Dabale Loubak, a camel breeder and Abourma's custodian, who claims to "know every stone, every nook and cranny" of this rocky massif.
The 41-year-old is from the Afar community, a historically nomadic people who wandered the arid fringes of Djibouti, Eritrea and Ethiopia, and have known about the carvings for generations.
"Our grandfathers told our fathers and then our fathers told it to us," said Loubak, a traditional turban and cloth skirt cladding his slim figure.
It was Loubak who guided the first French team to the site, trailed by a caravan of camels bringing food, sleeping quarters, and other essential equipment including a generator for the remote investigation.
Archaeologist Benoit Poisblaud, who was part of the team, still evokes with wonder the "extraordinary site", not found anywhere else in the region that he studied as a 25-year-old researcher.
"Abourma is a continuity, over several millennia, of passages, engravings, made by very different people: hunters, pastoralists, and those after... Thousands upon thousands of representations," he said.
The oldest carvings predate the birth of Christ by 5,000 years while newer examples were painted around two millennia ago, he said.
Africa boasts a wealth of archaeological sites, but few, especially rock art, have been fully studied, said Emmanuel Ndiema, head of archaeology at the National Museums of Kenya in Nairobi.
"Up to now, as we speak, we still get reports about sites here in Kenya, not even elsewhere," he said, estimating that just 10-20 percent of archaeological troves in sub-Saharan Africa had been properly researched.
This risks the universal value and preservation of these finds, experts say, which if nurtured could in time attract tourists and history buffs, generating much-needed government revenue.
However, greater visibility comes with its own potential cost for heritage.
Abourma, for example, receives so few visitors there are no fences, barricades or rules or any kind for those who make the journey to this vast, hidden-away expanse.
Loubak, however, is not too worried about threats to these millennia-old artworks, with eyes everywhere reporting the slightest disturbances or outsider presence.
"Nobody can come here without my knowledge," he said.
