Bayan Har Shan.
The Dropa.
In 1938, Chi Pu Tei, a professor of archeology at Beijing University took his students to explore a series of caves in the Bayan Har range in the Himalayas. There, deep in a series of caves and tunnels with walls that were squared and glazed, as if cut into the mountain with great heat, he found the "Dropa Disks" (large stone discs with tiny hieroglyphs) and a row of tiny tombs. The skeletons within had abnormally big heads, and small, thin, fragile bodies.
