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" !
