The mysterious circles in the Kasley area were noticed a few years ago. Then the members of the Ural branch of the "Cosmopoisk" movement accidentally stumbled upon them, studying satellite images of the surrounding forests. The two concentric circles associated with the famous "crop circles" could easily be mistaken for a UFO landing site.
Although, a variety of assumptions were considered. For example, that the military was involved in the appearance of strange figures. Looking ahead, we note that it was this version that turned out to be as close to the truth as possible.
Soon after the discovery of the "Kasli anomaly," as the seekers dubbed it, an expedition was organized to those places. The guys studied a strange polygon and found that the trees grew in spirals on a kind of stone embankments. In addition, we managed to find out the ownership of the site: it was related to the Kasli plant "Radiy". In Soviet times, he was also involved in secret military developments in the field of radio electronics. Researchers contacted the company, and since it was no longer a secret, one of the center's specialists solved the mystery of the circles.
- The circles were specially created for the movement of trucks, converted for testing radio devices. There were radio transmitters in the boxes of the trucks, to which a signal was sent from the Kasli radio plant. Researchers experimentally tested radio equipment and, possibly, were engaged in the calibration of devices, - according to "Kosmopoisk".
However, the man-made origin of the "anomaly" does not at all change the mysterious nature of the experiments that were carried out at the test site. After all, no one ever told what kind of equipment they tested, driving military trucks in spirals.
