Helankou Rock Art, Ningxia 宁夏贺兰口岩画
Helankou is a gorge on the eastern side of the Helan Mountains in western Helan County, Ningxia. On the cliffs and boulders on both sides of its mouth are more than a thousand rock carvings, mostly left by ancient nomadic peoples: human faces, animals and hunting scenes, the strange masks being the most striking. The gorge is deep and quiet, and blue sheep are often seen on the crags.
