Xia Qi Gu Wenquan

Xia Qi Gu Wenquan — 'Under Steep Valley Hot Spring' — is a naturally sulphurous geothermal spring in China, its name precisely locating the spring at the base of a steep valley — a geological formation that is often associated with increased geothermal activity where the overlying rock layers are thinner or where fault lines converge in the valley floor. Valley-bottom hot springs of this kind are among China's most atmospherically dramatic geothermal sites, their warm, mineral-rich water emerging in a confined and often spectacular natural amphitheatre of rock and forest. The spring provides naturally sulphurous, warm mineral water in a geologically dramatic Chinese valley setting.
