Silk Road City Guide - Korla

Originally located only in the Lop Nur area of Ruoqiang County, Yadan, which means "The steep Earthen Mound" in Uygur, has now become a world to indicate a special topography in dry areas. Because of strong water corrosion and fierce wind erosion, a series of parallel ditches and ditch ridges have formed in the clayrock area. These ditches and ridges, following the direction of the prevailing winds, are usually up to twenty meters long, with the longest several hundred meters long. They can be all sorts of shapes, and present a splendid sight. The "Dragon City" in the northeast part of Lop Nur is most magnificent.
