Dasht-e Lut in some scientific sources was also called the "Lut Deset" is located in south East of Iran.

It has divided to 3 main parts: southern Lut, Central Lut and Northern Lut.

It is about 175,000 Sq Km  in  area, which covers a region  surrounded  by Kerman,  South  Khorasan  and Sistan & Baluchistan Province.

In the Dasht-e Loot, strong winds blowing from east to west.

These winds took 120 days long  during  the  year  called  “ Sistan’s  one Hundred and twenty day  winds”  ( Sistani Winds). Sistn’s winds play a major role in creating morphological structures across the Lout desert which is called Kaluts.

There is a spot in Dasht-e Lout which is called the hottest place on earth. In five of the seven years—2004, 2005, 2006, 2007, and 2009—the highest surface temperature on Earth was found in the Lut Desert. The single highest LST recorded in any year, in any region, occurred there in 2005, when MODIS recorded a temperature of 70.7°C (159.3°F)—more than 12°C (22°F) warmer than the official air temperature record from Libya.

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;  they are  the  most  unique  structures  in  the  desert.  Kalouts are  similar  to  parallel tunnels  which  are  positioned  from  northwest  to  northeast.  Kaloots  are  80 km  in  width, 145 km in length, and in some cases 120 meters high; they are located in the west of Central Lut at a distance of 43 kilometers from Shahdad. From a distance, Kaluts look like the ruins of a big legendary city with grand palaces and buildings  both  short  and  high.  In  fact,  these  Kaluts  were  created  by  the  Erosions of wind  and  rain. The Kaluts are famous to "Sand Castles" !

The theory that Lut is the thermal center of the earth was proposed by Professor Stratil Sauer from the University of  Vienna  in  Austria  in  1952.  After  some  aerial  analysis,  the  west  part  of  Nosrat  Abad,  Rig-e- Yalan  introduced as the hottest place on earth. Theodore Mono confirmed the mentioned area among the hottest places on

earth.  According  to  NASA’s  maps,  the  hottest  temperature  on  earth  (70.7  centigrade  Celsius) was  recorded  in the lowest area of Lut —an area in the east of Kaluts— in 2005.

Iranian  researchers, including  Professor  Kardavani  and  Mahmoudi  believe  the  hottest  place  of  earth  is  located 

somewhere in this desert. Due to extreme heat, the best months to visit Dasht-e Lut are from November through February.

Lut Desert Inscribed on World Heritage List (UNESCO) as Iran’s First Natural Site.
