The Great Basin is characterized by Salt flats.

The Great Basin features extensive salt flats, particularly in areas such as the Bonneville Salt Flats and the saline playas found throughout the region. These salt flats are formed from the evaporation of water in lowlying areas, leaving behind mineral deposits, primarily sodium chloride (table salt). The Great Basin's unique topography, including its mountain ranges and enclosed valleys, contributes to the creation of these salt flats, which are notable for their stark beauty and unique ecosystems. Additionally, the presence of these features is indicative of the region's arid climate and limited water drainage.
