Lower Delongwan Petrified Wood Cluster

Lower Delongwan Petrified Wood Cluster

The petrified wood cluster is located on the north bank of the Baihe River in Xiadeliangwan Village, Qianjiadian Township, Yanqing County, Beijing, approximately 130 kilometers from downtown Beijing. The Qianjiadian petrified wood cluster is densely distributed and largely well-preserved. Its vast area and large quantity are truly rare in China. According to analysis, most of the petrified wood in Qianjiadian comes from coniferous plants such as pine and cypress. Some lie across mountain ridges, some stand upright on slopes, some resemble tree stumps, and others look like tree trunks. The petrified wood cluster prominently emerges from yellowish-gray shale and yellow-green sandstone, with very clear growth rings, creating an ancient and elegant landscape. The cluster extends northeastward from Qianjiadian Township to Shaliangzi Township over a distance of 8 kilometers, naturally distributed in a belt about 400 meters wide. The surfaces of the petrified wood stumps are yellowish-brown or grayish-white, with the largest diameter reaching 2.5 meters and most around 1 meter. On the eastern slope of Dongliang, there is a large expanse of fallen petrified wood, the most impressive of which is the “Stone Beam” west of Beiliang Village—a massive fossilized tree trunk with a girth of over 2 meters, lying across a mountain stream with both ends embedded in the hillside, forming a spectacular sight. In 2003, it officially passed the evaluation by geological experts from the Ministry of Land and Resources. It not only became Beijing’s first nationally approved geological park but also the country’s only geological park primarily featuring a petrified wood cluster.
