The Baigong Pipes: Ancient Technology or Alien Relics?

The Baigong pipes, which are also known as 白公山铁管 (Bai Gongshan Iron Pipes) and Delingha pipes, are a series of pipe-like features not officially identified but claimed in a 2003 magazine with no evidence as fossil trees or tree roots,[1] found on and near White Mountain (Chinese: 白公山; pinyin: Báigōngshān 'Mount Baigong'), about 40-kilometer (25 mi) southwest of the city of Delingha, in the Haixi Mongol and Tibetan Autonomous Prefecture, Qinghai Province, China.
