Dasht-e Lut, also spelled Dasht-i-Lut, is a large salt desert in southeastern Iran and is the world's 25th largest desert.

Iran is climatically part of the Afro-Asian belt of deserts that stretch 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 Dasht-e Lut is generally considered to be an abiotic zone.

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,[1] and is considered to be one of the driest places on Earth.[2][3][4]

Area of the desert is about 51,800 square kilometers (20,000 mi²).[5] 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 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 m (250 ft) in height.[1] This area is also riddled with ravines and sinkholes. The southeast is a vast expanse of sand, like a Saharan erg, with dunes 300 m (1000 ft) high, among the tallest in the world.[1]

Hottest land surface

Measurements of MODIS (Moderate-Resolution Imaging Spectroradiometer) installed on NASA's satellite "Aqua" from 2003 - 2005 testify that the hottest land surface on Earth is located in Dasht-e Lut and land surface temperatures reach here 70.7 degrees C (159 degrees F)[6][7][8][9][2][3][4]. Precision of measurements is 0.5 - 1 degrees K[10][11].

The hottest part of Dasht-e Lut is Gandom Beryan - approximately 480 km² large plateau covered with dark lava[12]. According to local legend this name (in translation from Persian - "Toasted wheat") originates from an accident where load of wheat left in the desert was scorched by the heat in a few days time[13].
