Circles on the field and other formations. Russia

Hunters for "plates" consider the case that occurred in 2006 in the Dobrovsky district to be an indisputable proof of the visit of aliens to the Lipetsk region.

The tractor SHPK "Krutovskoe" almost fell into a huge funnel that appeared at night in the middle of an arable field. The pit with a diameter of about 12 meters and a depth of almost six meters had perfectly smooth, as if someone had carefully polished the edges. Approximately 500 cubic meters of soil disappeared from the pit.

Geologists linked the anomaly with karst phenomena, marked the funnel on maps and recommended that local authorities fence the pit. Some villagers near her began to experience headaches, increased blood pressure, nausea. Others, on the contrary, felt a surge of strength. The mysterious funnel has become a local landmark.

It was repeatedly visited by groups of ufologists and fans of anomalous phenomena from many cities of the country. Curious greetings written by tourists to each other and aliens periodically appeared on the sandy walls. The Dobrovolsky machine operators, forced to maneuver on the field, most often remembered the "Martians" with unprintable words.
