Turpan Depression Below Bogda Mountains, China42.9N 89.1E
The Turpan Depression or Turfan Depression is nestled at the foot of China’s Bogda Mountains, in the Xinjiang Autonomous Region in far western China. It is situated around and south of the city-oasis of Turpan, about 150 km southeast of the provincial capital Ürümqi.
By some measures, it is also the hottest and driest area in China. An area of sand dunes is visible in the depression near the image center. It includes the second lowest exposed point on the Earth’s surface (dry Lake Ayding, -154m, a greyish area west of the dunes), after the Dead Sea. In fact, the entire depression is below sea level.
The Turpan Basin is a fault-bounded trough located in the eastern part of the Tian Shan. It covers an area of 50,000 km². The surrounding mountain ranges are: the central Tian Shan in the west, the Bogda Shan in the north-west, the Haerlike Shan in the north-west, and the Jueluotage Shan in the south. Beyond the surrounding mountain ranges lie the Junggar Basin in the north and the Tarim Basin in the south.
