The Baigong Pipes in Mount Baigong of China has an air of mystery, not just due to its’ questionable history and origin, but also because of it possible uses.

These pipes lead into a lake of saltwater and range in diameter from the width of a toothpick to about 16 inches. There is proof that nomadic people may have lived in these areas approximately 30,000 years ago… that’s it. No proof of civilization before that except for the 150,000-year-old pipes which were discovered back in 1996.
