  Atacama - Wikipedia, the free encyclopedia
The Atacama Desert is the driest desert on Earth (except perhaps for the McMurdo Dry Valleys in Antarctica) and is virtually sterile because it is blocked from moisture on both sides by the Andes mountains and by coastal mountains.
The driest part of the Atacama is between the coastal mountains and the Cordillera Domeyko, an area called the 'double rain shadow.' In this region, the Andes block moisture from the east, the Cordillera Domeyko block runoff from the Andes and the Coastal mountains block marine fog from the ocean.
The Atacama has rich deposits of copper and other minerals, and the world's largest natural supply of sodium nitrate, which was mined on a large scale until the early 1940s.
