Thadij
Thadij lies in western Qasim, near a valley bearing the same name. The surrounding plateau is broken by rocky hills and sand, including the dunes of Nufud al-Maysariyah and the heights of Jibal al-Mattayat. The wadi and neighbouring settlements form part of the wide, dry country west of the principal Qasim oases. Thadij should be distinguished from the similarly named town of Thadiq in Sudayr.
