Red Stones Forest, Geological park in Guzhang County, China

Red Stones Forest is a national geopark in Hongshilin Town, Guzhang County, Hunan. Its red carbonate rock forest formed in the Ordovician, about 480 million years ago, when the area lay on the seafloor. Differential erosion of softer and harder limestone layers sculpted the stone pillars after the ocean withdrew. The red color comes from impurities in the calcium carbonate.
