Vast Rub’ al Khali Desert in Saudi Arabia20.6N 47.8E
Much of the southern part of the Arabian Peninsula here is covered by the Rub’ al Khali, meaning “Empty Quarter”, an expansive sandy desert. Parts of Yemen, Saudi Arabia, Qatar, the United Arab Emirates and Oman can all be seen.
The Rub’ Al Khali covers about 250,000 square miles (650,000 square km) in a structural basin lying mainly in southeastern Saudi Arabia, with lesser portions in Yemen, Oman, and the United Arab Emirates. It is the largest area of continuous sand in the world, occupying more than one-quarter of Saudi Arabia.
The topography is varied. In the west the elevation is as high as 2,000 feet (610 m) and the sand is fine and soft, while in the east the elevation drops to 600 feet.
