Evaporite karst is unusual in sub-Saharan Africa but is well developed in gypsum and anhydrite on the northern Haud Plateau in Somalia. Shallow solution dolines up to 100 m in diameter are common, while many collapse dolines up to 50 m in diameter and 15m deep lead into caves 0.5-20 m below the surface, such as Ail Afwein (1275 m long) and Las Anod (1455 m long). Many caves contain water that is used for camels and goats.
