Dasht-e Loot (Template:Lang-fa, "Emptiness Desert"), also spelled Dasht-i-Loot and known as the Loot Desert, is a large salt desert in Kerman Province, Iran and is the world's 25th largest desert. The surface of the sand there has been measured at temperatures as high as 70.7 °C (159 °F),[1][2] and it is one of the world's driest and hottest places.
Description
Iran is climatically part of the Afro-Asian belt of deserts, which stretches from the Cape Verde islands off West Africa all the way to Mongolia near Beijing, China. 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). In near-tropical deserts, elevated areas capture most precipitation. As a result, the desert is largely an abiotic zone.
Iran's geography consists of a plateau surrounded by mountains and divided into drainage basins. Dasht-e Loot is one of the largest of these desert basins, 480 kilometers (300 mi) long and 320 kilometers (200 mi) wide,[3] and is considered to be one of the driest places on Earth.[4][5][6]
Area of the desert is about 51,800 square kilometres (20,000 sq mi).[7] The other large basin is 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 Loot 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.[3] 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.[3]
Hottest land surface
Measurements of MODIS (Moderate-Resolution Imaging Spectroradiometer) installed on NASA's Aqua satellite from 2003 to 2010 testify that the hottest land surface on Earth is located in Dasht-e Loot and land surface temperatures reach here 70.7 °C (159.3 °F), though the air temperature is cooler.[4][5][6][8][9][10] Precision of measurements is 0.5 K to 1 K.[11][12]
The hottest part of Dasht-e Loot is Gandom Beryan, a large plateau covered in dark lava, approximately 480 square kilometres (190 sq mi) in area.[13] According to a local legend, the name (in translation from Persian — "Toasted wheat") 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.
