About
About Al-Ghat Mustatil Field – Najd Plateau
Twenty-nine mustatil platforms on the eastern Najd limestone escarpment above Al-Ghat, the first major cluster east of the 300-km mustatil belt, marking the eastern limit of the phenomenon. Platforms are shorter (25–85 m) but share canonical architecture: twin long walls, bullnose heads and axial cairns. OSL dates bracket 4900–4200 BCE, slightly later than AlUla, suggesting eastward diffusion. The location atop a 100-m cuesta rim demonstrates mustatils were not harraat-restricted but occupied central Arabian interior during the African Humid Period lake phase.
Why it mattersEasternmost mustatil province edge, proving interior Najd occupation in Humid Period.
