Taklamakan Desert
There is very little water in the desert and it is dangerous to cross. Merchant caravans on the Silk Road stopped for relief at the thriving oasis towns. The key oasis towns, watered by rainfall from the mountains, were Kashgar, Marin, Niya, Yarkand and Khotan to the south, Kuqa and Turpan in the north and Loulan and Dunhuang in the east. Some of these are now ruined cities in sparsely inhabited areas in the Xinjiang Autonomous Region. The present population consists largely of Turkic Uyghur people.
