Al-'Uyayna

Al-Uyaynah lies in the Wadi al-Miyah, a long depression east of the al-Suman plateau. Its spring, known as Ayn Kanhar, once sent fresh water flowing northeastward across the valley floor. The depression, formerly called Wadi al-Sitar, contains springs and salt flats amid the dry country of eastern Arabia. Water made it a place of cultivation as well as a resource for the people of the surrounding steppe.
