Baetic System in the context of Casares, Málaga

The Middle Atlas (Amazigh: ⴰⵟⵍⴰⵚ ⴰⵏⴰⵎⵎⴰⵙ, Atlas Anammas, Arabic: الأطلس المتوسط, al-Aṭlas al-Mutawassiṭ) is a mountain range in Morocco. It is part of the Atlas mountain range, a mountainous region with more than 100,000 km, 15 percent of its landmass, rising above 2,000 metres. The Middle Atlas is the northernmost and second highest of three main Atlas Mountains chains of Morocco. To south, separated by the Moulouya and Um Er-Rbiâ rivers, lies the High Atlas. The Middle Atlas form the westernmost end of a large plateaued basin extending eastward into Algeria, also bounded by the Tell Atlas to the north and the Saharan Atlas to the south, both lying largely in Algeria. North of the Middle Atlas and separated by the Sebou River, lie the Rif mountains which are an extension of the Baetic System, which includes the Sierra Nevada in the south of Spain. The basin of the Sebou is not only the primary transportation route between Atlantic Morocco and Mediterranean Morocco but is an area, watered by the Middle Atlas range, that constitutes the principal agricultural region of the country.

The Barbary macaque is native to the Middle Atlas, and chief populations occur only in restricted range in parts of Morocco and Algeria. Snow persists in the Middle Atlas in the winter and can appear starting at 600 m above sea level.

The Penibaetic System (Spanish: Sistema Penibético or Cordillera Penibética) is the southernmost of the three systems of mountain ranges of the Baetic System in the southern Iberian Peninsula. It includes the highest point in the peninsula, 3,478 m high Mulhacén in the Sierra Nevada.

The Prebaetic System (Spanish: Sistemas Prebéticos or Sistema Prebético, also often referred to simply as Prebético) is a system of mountain ranges that forms the northeasternmost prolongation of the Baetic System in the southern Iberian Peninsula.
