Stone forest was formed by crustal movement 10 million years ago, when Mountain Longmen was rising rapidly, while the area to the west of Mountain Longmen was still undersea, and an enclosed lake was shaped in western Sichuan to the east of the mountain. Rocks weathered and eroded by water settled and piled up in the long history to form bibbley rocks, and finally became the hoodoo rock seen today as washed and cracked by rainwater. This type of gravel stone forest mainly consists of limestone and small amount of sandstone, quartzite and very little lava. The complicated components make it very rare in China and totally different from stone forests in Lu'nan of Yunnan and Gong County of Sichuan. |
