Yin Mountains

The Yin Mountains (zh-c|c=阴山, Yin Shan or Yinshan) are mountains in the steppe forming the southern border of the eastern Gobi Desert of the Inner Mongolia Autonomous Region, as well as the northern part of Hebei province.

The range stretches for about 1,000 km, beginning in the south-west as Lang Shan at the northern loop of the Yellow River, rising to some 2300 m above Linhe, falling to a more modest 1500 m north of Wuyuan, and widening to a broad highland north of Baotou, stretching north-east as far as Jehol.

Chinese sources of 200 BCE report that the range was a stronghold of the Xiongnu ruler Modu Shanyu. The Qin and Han dynasties's Great Wall follows its southern slopes.

Among other things, the range is notable for petroglyphs.
