The state-run news agency Xinhua in China reported on the pyramid, the pipes, and the research began by a team scientists sent to investigate in 2002.Though some have since tried to explain the pipes as a natural phenomenon, Yang Ji, a research fellow at the Chinese Academy of Social Sciences, told Xinhua the pyramid may have been built by intelligent beings.
The head of the publicity department at the local Delingha government told Xinhua the pipes were analyzed at a local smeltery and 8 percent of the material could not be identified.
The rest was made up of ferric oxide, silicon dioxide, and calcium oxide.
The pipes lead into a salty lake, though a twin lake nearby contains freshwater.
The surrounding landscape is strewn with what Xinhua described as “strangely shaped stones.” Rocks protrude from the ground like broken pillars.
