Beneath the windblown sands of the parched southern Arabian desert lie the ruins of the legendary city Ubar, confirmed by NASA satellite photos in 1992, and investigated onsite showing what was a large city fortress with towers and citadels, the ancient trading hub in the region, but obviously, not in that sea of sand which engulfs the old city’s ruins today, one of the driest places on the planet, bar none.
But during the Bronze Age, when Ubar is acknowledged to have been thriving, Arabia was a land of lush vegetation, with many lakes and interconnecting streams. The so-called Empty Quarter of Arabia, the lowest lying basin area of eastern and central Arabia, was an inland lake at that time, no doubt with ships from Sumer, Dilmun, and Old Dwarka, plying the water-routes for various cargos, among them copper which was mined in southern Arabia.
And Ubar was in that region, the city-state which controlled the region, a city of great fame and glory in ancient Arab lore, since buried beneath a sea of sand. The climate had rapidly degraded, beginning circa 1500 B.C., when what were similarly lush regions of the world began to also transition to the deserts which they are today, such as the Sahara, the deserts of northwest India and Pakistan, and the desert sands of Iran and Iraq, which were green with pastures and forests, streams and lakes, during the Ice Age.
