Searching for some circles a friend told me, had a lucky moment.
These walls were visible for the firts time in several days. we know where we are so, feel lucky.
Finally find the circles. also you can see themfrom google earth.
Happy. I’ve finded the circles he was was co
ncened about, to know what are they. Rumex acetosella is the dark that define the lines.
No alien theory. May be animals tied walked around a circle. but you can see them in google earth
