Takla Makan Desert #
The Takla Makan is one of the worlds largest and hottest sandy deserts. Water flowing into the Tarim Basin has no outlet so, over the years, sediments have steadily accumulated. In parts of the desert, sand can pile up to 300 m (roughly 1,000 ft) high.
The mountains that enclose the sea of sand - the Tien Shan in the north and the Kunlun Shan in the south - are also covered with what appears to be a significantly thicker layer of snow.
