This incredible phenomenon is a series of pipes located near Baigong Peak, 40 km southwest of Deling City in Qingai, China.
Baigong pipes are believed to be metal, and some of them are placed in an extremely old cave. This is a perfect example of a misplaced artifact often associated with ancient aliens.
The pipes were officially discovered in 2002, but locals have known of their existence for centuries. Most of Delinga's inhabitants believe that the pipes were made by aliens who came to Mount Baigong thousands of years ago. Of course, these stories meet with the expected skepticism, but everything changes when you walk to the nearest 60-meter pyramid, which is right at the top. However, the truth is that the pyramid has not yet been properly explored.
Near the base of Mount Baigong there are three caves, the largest of which is 6 m deep, and in places up to 8 m high. A vertical pipe with a diameter of 40 cm and a horizontal one passes through the inside, which runs under the floor of the cave.
Some of the pipes were inspected at a nearby foundry. Analysis showed that they are composed mainly of iron, but 30% of their composition is silica. According to the Chinese news agency Xinhua, the pipes are at least several centuries old, which means this metallurgical miracle is the work of a group of nomads who have too much free time.
Dozens of pipe holes were discovered high above the caves, meaning these nomads also had extremely advanced drilling technology, because there is no evidence of any industry in the area in modern history. Not far from Baigong is Lake Toson, through which there are still pipes, the smallest of which are the size of a toothpick. Some pipes appear above the surface of the water, others are hidden under the bottom of the lake.

Although Chinese scientists began their study back in 2002, there is still no information on convincing conclusions about the origin, application and creators of these mysterious pipes.
