Musti (nowadays El Krib) was located in a highly urbanized area of Africa Proconsularis, 12 km (90 miles) from Thugga, 10 km from Uchi Maius, and approximately 120 km from Carthage.  Musti was located at the intersection of four important roads: Carthage – Theveste, Hippo Regius – Carthage, Thuburbo minus – Tacapas via Vallis, and Carthage – Sufetula. Musti and the surrounding microregion included the southwestern part of the modern “plaine du Krib” comprising agricultural areas and fallow lands covering approximately 100 km². The microregion of Musti lies in the fertile alluvial valley of the Oued Khalled, a tributary of the River Bagradas (Majrada/Mejerda) – a vital agricultural area in the Tunisian Tell. The heavy soils of the valley were perfect for growing crops, which were watered by annual rainfall of 500–700 mm.
