The legend goes like this: Ubar, a rich and fabulous trading center of ancient Arabia rose out of the desert and then mysteriously vanished back into the sands. References to Ubar in the Koran, the Arabian Nights, and countless Bedouin tales told around desert campfires have captivated the imaginations of explorers and archaeologists. But all searches were fruitless and the city remained lost.

Now, centuries after Ubar's disappearance, a combination of hard work, dedicated research, and remote sensing technology has perhaps unraveled this ancient mystery.
