Ramlat al-Sab'atayn

The Ramlat al-Sab'atayn (Arabic رملة السبعتين) is a region of desert in north-central Yemen. It comprises mainly transverse and seif dunes and covers an area of about 100 by 240 kilometres (60 by 150 mi), roughly 26,000 square kilometres (10,000 sq mi).^[1] The area includes part of what was known to medieval Arab geographers as the Ṣayhad. It extends from al-Khawr to the edge of the Rub' al-Khālī or Empty Quarter. It includes the Yemeni muhafazahs of al-Jawf, Ma'rib and Shabwa.
