The said lake is in actual fact a part of the salt desert of Iran and is located to the east of Qom. It is a section of an ancient lake, currently dried up and rich in mineral sedimentation due to gradual evaporation. This salt desert lies amidst the provinces of Khorassan, Sistan, Qom, Esfahan and Yazd. The Salt lake contains water only in the winter months, whereas in summer a crust of salt attracts attention. This region experiences an extremely dry climate and the difference between day and night temperatures range till approximately 70° C. This difference in temperatures make the rocks of the surrounding elevations crack, crumpling into mounds of sand, and air currents cause them to move.
