Zhuoma Canyon is on National Highway 109, 100 kilometers southwest of Naqu Town. It is about 4,700 meters above sea level. There is a canyon next to Sangdangang Sangshen Mountain. There is a large leeward, pleasant climate, lush vegetation, and four precious Tibetan medicines such as saffron, mother of shellfish, winter worm, summer grass, and snow lotus. The meadows of the cold belt have been partially covered by ice and snow, a sight known as the "four-color polar".
