Quick Summary

The Mid-Sahara Rise is a landform located in the central Sahara Desert, primarily in northwestern Chad, extending into Niger and Libya. This mountainous region is characterized by volcanic massifs and is composed of eruptive rocks that have pushed through a substratum of crystalline rocks covered by sandstone. The highest point in the entire Sahara Desert, Mount Koussi, is part of the Tibesti Mountains within the Mid-Sahara Rise, reaching an elevation of 11,204 feet (3,415 meters). The area also features dry watercourses that suggest a past with a more humid climate. The Mid-Sahara Rise is known for its mineral wealth, including deposits of tungsten, tin, oil, and uranium.12
