![]() The yardangs in this desert are so extensive it is said that they can be seen from space The hottest spot on Earth with more than 70 degrees celsius recorded by NASA in 2005 in the southwest of Rig-e Yallan. Some of its important natural features are the highest sand dunes of the world with more than 475 meters high, situated in Rig-e Yallan The highest kalutes (yardangs) throughout the world with more than 155 meters high. The high number of natural phenomena throughout the year and the richness of culture in the local communities, turn this desert into a place of natural and cultural importance. Landform evolution in the Quaternary period in this desert represents a particular history of geological and geomorphological changes. The river flows along 2000 km long, from Ravar Mountains passing the west margin of Gandom Beryan into the salt depression. The presence of the river in Lut increases the singularity of the desert. Another unique feature of the desert is the Shur river. The Hamada plain in the central part of the Lut has a reverse triangular shape pointing towards the south to Shurgaz Hamun playa. The severe hot daily temperature decomposes rock outcrops in the mountains that get deposited on the plains. The geomorphologic conditions of the central part of the Lut are developed as a pebble and sand plain. The area of the core zone is about 23,000 square kilometers and the protected area, that works as a buffer zone, is about 18,000 square kilometers which includes Rig- e Yallan (sand dunes), Kalut (yardang), Nebka (depressions), Shur river, Gandom Beryan (plateau covered With dark lava) and the central Hamada (Desert pavement). ![]() NASA images created by Jesse Allen, Earth Observatory, using data provided courtesy of the NASA/GSFC/MITI/ERSDAC/JAROS, and U.S./Japan ASTER Science Team.The Lut Desert is located in the southeast part of Iran among three provinces of Kerman, Sistano Baluchestan, and Khorasan-e Jonubi. Astronauts on the International Space Station photographed salt lakes from Dasht-e Lut and nearby faulted rocks on February 28, 2006. ASTER acquired this image on July 17, 2003.ĭasht-e Lut’s dramatic landscapes are a popular remote-sensing target. Golden dunes make swirling pattenrs across the image, becoming less tightly packed in the bottom of the scene. In this image, the white areas are saltpans-the aftermath of water that drained into the basins among the dunes and later evaporated. ![]() This area consists of sand, and it contains some of the world’s tallest dunes, some reaching a height of 300 meters (1,000 feet). The picture on the right shows part of the southeastern portion of Dasht-e Lut. ASTER acquired this image on May 13, 2006. These wind-sculpted ridges are known as yardangs, and geologic research has determined that Iran contains some of the world’s largest yardangs. The strong diagonal lines result from wind erosion that has carved deep troughs and sharp ridges into the landscape. ![]() The picture on the left shows part of the central portion of Dasht-e Lut. These images, captured by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA’s Terra satellite show landscapes so different, one can scarcely imagine they come from the same part of the world, let alone the same desert basin. Although the entire salt desert has just one name, it has more than one appearance. The desert fills a low basin that stretches southward from the Khorasan province into the Kerman province. Roughly 480 by 320 kilometers (300 by 200 miles), Dasht-e Lut is a large salt desert in southeastern Iran.
