Mysterious ancient metal Pipes inside a cave 1

A series of mysterious ancient pipe-like features named Baigong Pipes, found on and near Mount Baigong, about 40 km southwest of the city of Delingha, in the Haixi Mongol and Tibetan Autonomous Prefecture, Qinghai Province, China.   Have a look at the video…

Some of the Baigong Pipes are reported to be associated with three caves in Mount Baigong. These caves are reported to occur within the front face of Mount Baigong. The mouths of the two smaller caves have collapsed. Only the largest cave, which is 6 meters (18 feet) high, can be entered. The vague resemblance of the top of Mount Baigong to a pyramid has been the focus of much fringe speculation.

The most recent researchers to examine the pipes believe that the metallic phenomenon are in fact fossilized tree root casts. The rusted tubes being the result of tree roots that underwent the processes of pedogenesis (the process that forms soils) and diagenesis (transformation of soil into rock). Further experiments confirmed that the pipes contain organic plant material and even microscopic tree rings. Overflow from an extinct lake once carried these roots to where they stand now.

So while they aren’t part of an alien sewer system, the pipes are evidence of the Earth’s ability to create strange and remarkable objects.
