![]() ![]() The crests or summits of the largest of these yardangs are rounded or flat all others are narrow. Lying parallel to the prevailing north-north-west winds, the yardangs are separated by troughs measuring 330 feet (100 meters) or more. Rising up to 282 feet (80 meters), these streamlined ridges have been carved by the wind out of the silty clay and sand lining the desert floor. In the western part of Dasht-e Lut lie some of the world's most prominent yardangs. Iran is famous for mega yardangs in Shahdad, Kerman, where thousands of tourists visit every year. Over time, the sand wears down the surface into beautiful streamlined shapes that are aligned with the prevailing sand-moving winds. On Earth, they are most commonly found in deserts where there is a sand supply, which abrades the surface when moved by the wind, and soft sedimentary rocks that the sand easily erodes. The word is derived from the Turkic word yar, which means ridge or steep bank. Kalout (Yardang) A yardang (Kalout) is a topographical feature that has been carved out of a surface by the wind. Extremely barren, the desert contains the only region free from any life, including the existence of bacteria, on Earth! Certain areas of the desert reportedly receive no rain. Among the driest places on the planet, it receives an average of only 1.2 inches (3 centimeters) of rain a year. Day and night temperatures during a year can differ up to 70☌. Temperatures can reach 50 ☌ in summer, and the average temperature in January is 22 ☌. The Dasht e Kavir's climate is almost rainless and the area is very arid. It is named after the salt marshes (Kavir) located there. The area of this desert stretches from the south hillside of the Alborz mountain range in the northwest to Dasht-e Lut ("Emptiness Desert) in the southeast and is partitioned between the Iranian provinces of Khorasan, Semnan, Tehran, Isfahan, and Yazd. It is about 800 kilometers (497 mi) long and 320 kilometers (198 mi) wide with a total surface area of about 77,600 km (-30,000 mi). In 2005, a temperature of 1593 degrees Fahrenheit was measured, the highest reading ever officially confirmed for a location on Earth.ĭasht-e Kavir (Great Salt Desert) Dasht-e Kavir (Central Desert), also known as Kavir e Namak or Great Salt Desert is a large desert lying in the middle of the Iranian Plateau. In five of those years - 2004, 2005, 2006, 2007, and 2009 - the hottest spot on Earth could be found in the Lut. (What a dreadful job that would be.) Though maintaining a weather station Is Impractical in the Lut, a NASA satellite equipped with a moderate resolution imaging spectroradiometer (MODIS) was able to measure temperatures here from space, during a seven-year study. Iran's Lut Desert, an area so parched and desolate that no one is around to regularly monitor temperatures. ![]() They offer a prospect of desolate waste that extends almost continuously from within 50 km of Tehran to Afghanistan and the Persian Gulf.ĭasht-e Lut (The hottest place on Earth) Here it is the hottest place on Earth. Iranian Kavirs (deserts) have attracted special interest and may be unique in the variety of their composition and surface types. Except for some scattered oases, these deserts are uninhabited. The eastern part of the plateau is covered by two small desserts, the Dasht e Kavir (Great Salt Desert) and the Dasht-e Lut. The average elevation of this plateau Is about 900 meters (2,953 U, but several mountains of this plateau exceed 3,000 meters (9,813 ft). The center of Iran consists of several closed basins that collectively are referred to as the Central Plateau. They are both some of the aridest and maybe hottest areas of their kind in the world. The well-known deserts of Iran are in two major regions:ġ) Dasht-e-Kavir, and 2) Kavir-e-Lut. Iran is situated on a high-altitude plateau surrounded by connected ranges of mountains. Where you can hardly find water and the living conditions are intolerable. This word always reminds us of an arid area with few plants. ![]()
