The curving sands in central northern Iran’s salt desert, Dasht-e Kavir, can be seen in this image from the Ikonos-2 satellite. Here, clays and sand soils have a high surface salt content owing to the concentration of minerals from high summer evaporation. Iran is one of the world’s most important mineral producers. Earth-observing satellites are useful for finding and monitoring natural resources like minerals.
