Báilóngduī

Bailongdui, the “White Dragon Mounds”, is a maze of wind-carved ridges northeast of Lop Nur. Pale salt crusts on their crests give the landforms their name, while the parallel ridges and hollows make passage difficult. In Han times travellers from the east crossed this forbidding country on the way to Loulan, where the routes divided toward the northern and southern oases of the Tarim Basin.
