Dunhuang Yardang National Geopark is sited in China’s Gansu Province, 108 kilometers (67 miles) to the northwest of Dunhuang city. It extends 25 kilometers (15 miles) from east to west and 13 kilometers (8 miles) from north to south. The park is well-known for Yardang landscape, which is a typical wind erosion landform. Yardang in Uygur language means a small mound with steep walls. The area contains 77 ruins and huge rocks formations in sculpted shapes. These images are from my visit in 2012 on my silk route journey, which finished at the Jade Gate in China.
