The last part of the Atlas Mountains is the High Atlas.
The High Atlas in central Morocco rises in the west at the Atlantic coast and stretches in an eastern direction to the Moroccan-Algerian border.
The oldest portion of the range is in the west, near the coast. Its high point is the Jbel Toubkal at a height of 13, 600 ft. The mountain consists of Jurassic and Cretaceous formations notched by deep erosion-carved valleys.
The central part of the High Atlas is a solid chalk mass reaching an altitude of 8200 ft. The contrasting landscapes remind visitors of the Colorado, with its high plateaux, its gorges and box canyons, and its peaks sometimes splintered by erosion. Several peaks in this area exceed 13,000 ft.
This massif became an internationally famous paleontological site after the discovery of the bones of the completely unknown ancestor of the dinosaurs, This dinosaur is also named Tazoudasaurus, after the name of the village of Tazouda where it was discovered.
