In 1991, Geologists found several mysterious machine pieces while excavating in the mysterious Ural mountains, at the confluence of the Kozhim, Narada, and Balbanyu rivers, while looking for gold deposits. The pieces were embedded in 100,000 year old rock and have various machined shapes and distinct chemical compositions. Ooparts (out of place artifact), as they are often called, are items that are found that seem impossibly out of place. These are the most perplexing ooparts found so far.
The most mysterious type of part found were nanospirals, spirals so small they could only be seen with a microscope, down to 1/10,000th of an inch. Based on their estimations, the spirals had to be 100,000 to 300,000 years old. They were found between two distinct strata with the top layer being 20,000 years old and the layer beneath being 300,000 years old.
According to Russian Academy of Sciences, the larger pieces were made mostly of copper but the smaller pieces were made of tungsten and molybdenum. The geologists studying the metals said they were not of a natural origin. According to Dr. E.W. Matvejeva, from the Central Scientific Research Department of Geology and Exploitation of Precious Metals, they are of a “technological origin”.
According to the Epoch times, the artifacts have been studied at facilities in Helsinki, St. Petersburg, and Moscow. One of the principal researchers by the name of Dr. Johannes Fiebag died in 1999 and there do not seem to have been any subsequent investigations.
At first, there was a theory they were parts that had fallen from rockets from a launch site in Plesetsk. A report in 1996 ruled that possibility out, saying the parts were found at too great a depth.

The Ural mountains are full of mysteries, the most famous of which is the Dyatlov Pass Incident where a group of Russian hikers were all found dead of a mysterious compelling force. The area is famous for shamanism and numerous UFO sightings. Is this the evidence of an alien presence hundreds of thousands of years ago? The evidence is still out but it definitely warrants further research!
