The Dropa Stones are supposedly a collection of circular stones found in a cave in Tibet in 1938. They were discovered by Chinese archaeologist Chi Pu Tei. They purportedly tell of aliens coming to earth in 10,000 BC. No claims have been verified, and so the Dropa Stones are part of a highly elusive mystery.
High in the Baian-Kara-Ula mountains in Western China, Chi Pu Tei led a group of students on an expedition surveying interlinking caves in the Himalayas. The caves were apparently remarkable in that they appeared to have been carved using a technically-advanced cutter. What was most incredible about the expedition of Chi’s team is the fact that they stumbled across 400 skeletons of an unidentifiable small creature. Each creature would have stood at little more than four-feet high.
