Crop Circles are geometric patterns that appear mysteriously in crop fields. The crop is not cut, but is usually laid flat and most often swirled into an attractive floor pattern. Most patterns appear in cereal crops such as wheat and barley, but circles have been known to occur (in lesser numbers) in oilseed rape, maize, linseed, grass and even borage – to name a few. In the US many circles appear in soya, as it grown prevalently in that part of the world.
