Dropa Stones

The Dropa stones, otherwise known as the Dzopa stones, Dropas stones or Drop-ka stones, are said by some ufologists and pseudoarchaeologists to be a series of at least 716 circular stone discs, dating back 12,000 years, on which tiny hieroglyph-like markings may be found.Each disc is claimed to measure up to 1 foot (30 cm) in diameter and carry two grooves, originating from a hole in their center, in the form of a double spiral. The hieroglyph-like markings are said to be found in these grooves.
    For twenty years the Dropa stones were said to have sat in storage before they were given to Tsum Um Nui for study in 1958. It is said the he came to the conclusion that the grooves on the discs were actually very tiny hieroglyphs, none of which were of a pattern that had been seen before, and which can only be seen with the use of a magnifying glass. By 1962, he had allegedly deciphered them into a story that told of a spacecraft that crashed landed in the area of the cave, the Bayan Har Shan region and that the ship contained the Dropa people who could not fix it and therefore had to adapt to Earth. Further, his research claims that the Dropa people were hunted down and killed by the local Ham tribesmen for a period. Tsum Um Nui noted specifically that one glyph apparently said "The Dropa came down from the clouds in their aircraft. Our men, women and children hid in the caves ten times before sunrise. When at last they understood the sign language of the Dropas, they realized that the newcomers had peaceful intentions"
    Russian researchers requested the discs for studying, and allegedly several were shipped to Moscow. Once there, it is said that they were scraped for loose particles and put through a chemical analysis which revealed that they contained large amounts of cobalt and other metallic substances. As recorded in the Soviet magazine Sputnik, Dr. Vyatcheslav Saizev describes an expriment where the discs were supposedly placed on a special turntable whereby they were shown to 'vibrate' or 'hum' in an unusual rhythm as though an electric charge is passing through them.
