The Rub Al Khali Desert
The Rub Al Khali Desert (the “Empty Quarter”) is the sand desert encompassing most of the southern third of the Arabian Peninsula. The desert covers some 650,000 km2 (250,000 sq mi) including parts of Saudi Arabia, Oman, the United Arab Emirates, and Yemen. It is part of the larger Arabian Desert. The Rub Al Khali Desert is one of the driest regions in the world, is virtually uninhabited, and is largely unexplored. However, vast reserves of petroleum are present beneath its sands.
