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" !
