The Lut Desert, widely referred to as Dasht-e Lut (Persian: دشت لوت, "Emptiness Plain"), is a large salt desert located in the provinces of Kerman and Sistan and Baluchestan, Iran. It is the world's 25th-largest desert, and was included on UNESCO's World Heritage List on July 17, 2016.[1] The surface of its sand has been measured at temperatures as high as 70 °C (159 °F),[2][3] making it one of the world's driest and hottest places.
Description
Iran is climatically part of the Afro-Asian belt of deserts, which stretches from Mauritania all the way to Mongolia. The patchy, elongated, light-colored feature in the foreground (parallel to the mountain range) is the northernmost of the Dasht dry lakes that stretch southward 300 kilometers (190 mi).[clarification needed]
Iran's geography consists of a plateau surrounded by mountains and divided into drainage basins. Dasht-e Lut is one of the largest of these desert basins, 480 kilometers (300 mi) long and 320 kilometers (200 mi) wide,[4] and is considered to be one of the driest places on Earth.[5][6][7]
The area of the desert is about 51,800 square kilometres (20,000 sq mi),[8] the largest in Iran except for the Dasht-e Kavir. During the spring wet season, water briefly flows down from the Kerman mountains, but it soon dries up, leaving behind only rocks, sand, and salt.
The eastern part of Dasht-e Lut is a low plateau covered with salt flats. In contrast, the center has been sculpted by the wind into a series of parallel ridges and furrows, extending over 150 km (93 mi) and reaching 75 metres (246 ft) in height.[4] This area is also riddled with ravines and sinkholes. The southeast is a vast expanse of sand, like a Saharan erg, with dunes 300 metres (980 ft) high, among the tallest in the world.[4]
Geology
According to one study, more than half of the desert's surface is covered by volcanic rocks. Evaporites can be observed during hot periods. [citation needed]
Hottest land surface
The Moderate-Resolution Imaging Spectroradiometer installed on NASA's Aqua satellite recorded that from 2003 to 2010 the hottest land surface on Earth is in Dasht-e Lut, with land surface temperatures reaching 70.7 °C (159.3 °F), though the air temperature is cooler.[5][6][7][9][10][11] The precision of measurements is 0.5 K to 1 K.[12][13]
The hottest part of Dasht-e Lut is Gandom Beryan, a large plateau covered in dark lava, approximately 480 square kilometres (190 sq mi) in area.[14] According to a local legend, the name (Persian — "Toasted wheat")[clarification needed] originates from an accident where a load of wheat was left in the desert which was then scorched by the heat in a few days.
