Barkol Singing Sand Mountain is a sand mountain in the territory of Barkol Kazakh Autonomous County, Xinjiang. In the desert or sand dunes, due to the influence of various climatic and geographical factors, fine sand particles mainly composed of quartz are formed. Due to wind vibration, sand sliding or mutual movement, many sand particles rotate in the airflow, and the holes on the surface cause the "diabolo" effect, which produces a buzzing sound. The Singing Sand Land is mainly desert in western China. These sand dunes are piled up into mountains, so it is also called Singing Sand Mountain.
