This subrange of the Andes runs north-south, parallel with the Chilean coast. Pictured here is Cordillera de la Sal ("Salt Range’). If you’re traveling in the region, be sure to pack lots of water. This is the Atacama Desert, a region so dry and at such a high elevation, that NASA has used it to simulate Mars.
