Harrat al-Sham

The Ḥarrat al-Shām (Arabic: حَرَّة ٱلشَّام),[1][nb 1] also known as the Black Desert,[2] is a region of rocky, basaltic desert straddling southern Syria and the northern Arabian Peninsula. It covers an area of some 40,000 km2 (15,000 sq mi) in the modern-day Syrian Arab Republic, Jordan, Israel and Saudi Arabia. Vegetation is characteristically open acacia shrubland with patches of juniper at higher altitudes.[3]

The Harrat has been occupied by humans since at least the Late Epipalaeolithic period (c. 12,500–9500 BCE).[4] One of the earliest known sites is Shubayqa 1 (occupied c. 12,600–10,000 BCE),[4][5] where archaeologists have discovered the remains of the oldest known bread.[6]

The Harrat comprises volcanic fields formed by tectonic activity from the Oligocene through to the Quaternary period.[7] It is the largest of several volcanic fields on the Arabian Plate,[8] containing more than 800 volcanic cones and around 140 dikes.[7] Activity began during the Miocene; a younger eruptive stage, at the SE end of the volcanic field, occurred during the late-Pleistocene and Holocene.[9] It is known to have erupted in historic times.[10][11]

The Jabal al-Druze, al-Safa and Dirat al-Tulul volcanic fields, among others, form the northern and Syrian part of the harrat. The Saudi Arabian portion of the Harrat Ash Shamah volcanic field extends across a 210 km (130 mi)-long, roughly 75 km (47 mi)-wide NW-SE-trending area on the NE flanks of the Sirhan Valley and reaches its 1,100 metres (3,600 ft) high point at Jabal Al-Amud. It is in the Tabuk Region of northwest Saudi Arabia.[12][13] and is one of a series of Quaternary volcanic fields paralleling the Red Sea coast.
