Hadhramaut Mountains

The Hadhramaut Mountains, also known as the "Mahrat Mountains", are a mountain range in Yemen. They are contiguous with the Omani Dhofar Mountains to the northeast, and James Canton considered Aden in the southwest to be in the mountains' recesses.
Historically, the area was ruled by Qu'aiti and Kathiri sultanates. The tribal society grows wheat and millet, produces also dates, coconuts, and coffee. The area was also known for its frankincense.

Geology

The south side of the mountains touches the Gulf of Aden, with steep cliffs descending onto a narrow and arid coastal plain. The northern slopes are lowering onto the Rub' al Khali desert. The broad mountain plateau is intersected by deep wadis cut by seasonal streams that generally flow in the northern and northeastern direction emptying into a main channel that makes a southeast swing of to the ocean. Despite seasonality of the streams, the water is generally available year-round sub-surface in the wadis.
