Anti-Atlas Mountains, Morocco

Another image from the Earth Observing System (EOS) mission, this photo was taken on June 13, 2001, by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA's Terra satellite. The “Anti-Atlas Mountains of Morocco formed as a result of the collision of the African and Eurasian tectonic plates about 80 million years ago….The yellowish, orange and green areas are lime stones, sandstones and gypsum; the dark blue and green areas are underlying granitic rocks,” according to JPL.
