I went with friends to a place in the desert who are spring waters and I took them to see a place I know with petrogliphs. When we were preparing to have lunch, someone saw this cirlces. Soem of us, got into it, and felt very bad. Nausea, headache, and extreme fatigue. That is a hot place of ufo sightings. I have seen strange ligths many times out there.There was not car prints, or foot prints around them, there was no crossing between the circles.
