The Lut Desert, widely called as Dasht-e Lut, large salt desert located in the provinces of Kerman and Sistan and Baluchestan, Iran. It is the world's 27th-largest desert, and was inscribed on UNESCO's World Heritage List on July 17; 2016. The Lut Desert is divided into three geographic units: North Lut, Central Lout and South Lut. The most alluring part of the Lut Desert is, the Central Lut. In terms of geomorphology, Central Lut is divided into three main parts: Pediment, Kaluts (Yardangs) and Sand dunes. The Pediment is situated in south of the Shahdad region with the width of 5 to 10 kilometers in strips and it is covered with sand, silt and salt.
Shahdad desert is one of the most important Iran and Kerman’s natural special attractions that its magnitude and magnificence are seemed to be unbelievable by the unknowns. The desert is one of the tourism wonderful places; specially the shahdah kaloots.
One of the most exciting geomorphological structures of Lut is the special bumps called Kalut which is the biggest natural clod structure in the world; furthermore, it is the most unique structures in the desert and it is the only Iran UNESCO natural world heritage site. This area of the Geologists’ poles geothermal is known. They are located in 40km east and north-eastern of Shahdad in Kerman province; they have generated by the extreme soil and water erosion and extended from north-west to south-east. The “Kaluts have covered a part of the west fringe of Lut desert with the average width of 80km and average length of 145km. There is little vegetation in the desert region.
The hottest part of Dasht-e Lut is Gandom Beryan, a large plateau covered in dark lava, approximately 480 square kilometers in area. The 15km north of Shahdad in the Kaluts lays Shahdad Gandom Beryan (The hottest part of Dasht-e Lut), which has been recorded as the hottest surface temperatures on Earth - between 70 to 100° in summer - where most bacteria even cannot survive. Other attractions include: Salty River Flow with a high concentration of crystallized salt, a unique Desert Mirage, the Deepest Point in Iran, and Beautiful Star and a Moonlit Sky.
Between June and October, this arid subtropical area is swept by strong winds, which transport sediment and cause Aeolian erosion on a colossal scale.
This region represents an exceptional example of ongoing geological processes related to erosional and depositional features in a hot desert. The yardang/kalut landforms are widely considered the best-expressed in the world in terms of extent, unbroken persistence, and height. The Lut sand-seas are amongst the best developed active dune fields in the world, displaying a wide variety of dune types, (crescent ridges, star dunes, complex linear dunes, funnel-shaped dunes).
In the kaloot; Some desert camps have been built that are used for night settlement.
