The Empty Quarter

Rub’ al Khali — or “The Empty Quarter” — is the largest sand desert in the world. It covers 251,000 square miles (650,000 sq. km) and includes parts of Saudi Arabia, Oman, Yemen, and the United Arab Emirates. In the center of the desert there are a number of raised, hardened formations that were once the sites of shallow lakes, thousands of years ago.
