Dasht-e Kavir is a vast desert in the Iranian Plateau also known as the Great Salt Desert and is named after the large salt marshes that have formed on the land. The climate of Dasht-e Kavir is extremely dry and hot.
Frequent heavy storms have an impressive impact on the environment, shaping the land with colossal sand hills and distinct erosion. The salt marshes are the result of surface evaporation caused by high temperatures and a lack of rain. As the land dries out, salt crusts form on the ground.
Much of the area is unexplored and the desert largely uninhabited. Salt-marshes (kavirs) have properties similar to quicksand; therefore traveling in the Dasht-e Kavir is extremely dangerous. All human settlements are restricted to the hills and surrounding mountains.
