High Atlas

High Atlas, also called the Grand Atlas Mountains (Arabic: الاطلس الكبير‎ and French: Haut Atlas) is a mountain range in central Morocco in Northern Africa.

The High Atlas rises in the west at the Atlantic Ocean and stretches in an eastern direction to the Moroccan-Algerian border. At the Atlantic and to the southwest the range drops abruptly and makes an impressive transition to the coast and the Anti-Atlas range. To the north, in the direction of Marrakech, the range descends less abruptly.

The range includes Jbel Toubkal, which at 4,167 m is the highest in the range and lies in Toubkal National Park. The range serves as a weather system barrier in Morocco running east-west and separating the Sahara's climatic influences, which are particularly pronounced in the summer, from the more Mediterranean climate to the north, resulting in dramatic changes in temperature across the range. In the higher elevations in the range snow falls regularly, allowing winter sports. Snow lasts well into late spring in the High Atlas, mostly on the northern faces of the range.

The High Atlas forms the basins for a multiplicity of river systems. The majority of the year-round rivers flow to the north, providing the basis for the settlements there. A number of wadis and seasonal rivers terminate in the deserts to the south and plateaux to the east of the mountains.
