Klots are found in different parts of Iran. But the largest of them is located in Kerman province and around the city of Shahdad, and for this reason they are known as Shahdad Klots.
Kaluts are natural features that occur due to environmental erosion in sedimentary mountains or hills of desert areas. This erosion can be due to wind or due to rain and running water in the riverbed.
Various theories have been proposed for this phenomenon, the most likely of which is the increase in ground pressure due to the presence of hydrocarbon gases.
