A synonym for salt flats is salt pans. This refers to large, flat areas of land that are covered with salt, typically found in arid regions. Salt pans may also be referred to as salt deserts or saline flats. They are formed as a result of the evaporation of water from shallow lakes or seas, leaving behind a crust of salt. These expanses of salt are often strikingly beautiful, their white surface reflecting sunlight and giving the illusion of a never-ending white landscape. Salt pans are also important sources of salt for human consumption, with many salt mining operations taking place in these regions around the world.
