Dasht-e Kavir

Salt domes form swirling bands of color across Dasht-e Kavir, the Great Salt Desert of central Iran. Tens of millions of years ago, an arm of the ancient Tethys Ocean flooded this region and then evaporated, leaving behind a layer of salt up to 4 miles (6–7 km) thick. Over time the salt rose through the sediment above and bent those layers into concentric rings.
