Dasht-e Lut Desert Basin in Iran30.4N 58.4E
The tan area near the center of this image is part of the Dasht-e Lut, a large salt desert in southeastern Iran. It is the world’s 25th largest desert. 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
Itis considered to be one of the driest places on Earth. 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. 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.
