There are several closed basins in the central part of Iran that are referred to as the Central Plateau. The average elevation of this plateau is about 900 meters but several mountains of this plateau exceed 3000 meters. The eastern part of the plateau is covered by two salt deserts, Dasht-e Kavir and Dasht-e Lut. Except for some scattered oases, these deserts are uninhabited.
Iran deserts have attracted special interest and may be unique in the variety of their composition and surface types. These deserts can be seen almost from within 50 km of Tehran to Afghanistan and the Persian Gulf.
