Mysterious geoglyphs found in Russia

Photographer Ruslan Rybakov and correspondent Dmitry Popugin
went to Tatyshev Island on the morning of April 22, 2022 to
investigate the mysterious crop circles. The day before, Ruslan
Rybakov published his footage from a videocopter, which captured
a strange structure. According to journalists from the island, the
diameter of the object is approximately 25 meters. Furrows are quite
deep, about 20 cm high and 60 cm wide. According to the researchers,
the structure was clearly created by hand, most likely with the help
of shovels: the earth was dug out and stacked in cubes.
