Where is Tianzi Mountain located?

Tianzi Mountain is a mountain in Zhangjiajie in the Hunan Province of China, close to the Suoxi Valley in South Central China. Before the Ming Dynasty, Tianzi Mountain was known as "Qingyan Mountain" because of its green stones. The mountain is named after the early Ming dynasty farmer Xiang Dakun of the Tujia ethnic group, who led a successful local farmers' revolt and called himself "Xiang Wang Tianzi", meaning son of Heaven and which is the traditional epithet of the Chinese emperor.

The highest pillar of Tianzi Mountain is Kunlun Peak with an elevation of 1,262.5 metres (4,142 ft 1 in) and the lowest pillar is Shilanyu with an elevation of 534 metres (1,752 ft). Tianzi Mountain is a part of the Wulingyuan Scenic Area and was added to the UNESCO World Heritage List in 1992.

The mountains are quartz sandstone and were formed about 400 million years ago through irregular rising patterns of the earth's crust, and with about 318 million years of erosion these tall and skinny mountains were formed. This geological formation belongs to the "New Cathaysian" tectonic system.
