Summary: The following outline is a summary of theories and working hypotheses regarding the mechanisms of crop circle formation. What is presented here is a synopsis of published findings and theories, and in no way does it pretend to be the final word.

There are a number of observations that have been made over the years that seem to indicate that there are particular characteristics that "genuine" (or non-mandmade) formations appear to exhibit. Some of the observations are listed below:
In what kind of crops do they occur?Crop circles have been reported in mostly barley and wheat. But, they also appear in corn, oats, oilseed rape (canola), grass, ricefields, trees, sand, and even snow.
The physical changes (listed below) documented in crop circle plants by Michigan biophysicist W.C. Levengood have been determined by evaluating hundreds of sample plants -- both downed and standing -- taken from inside the overall perimeter of each formation against hundreds of control plants taken at varying distances...
They are mentioned in academic texts of the late 17th Century, and almost 200 cases- some with eyewitness accounts- have been reported prior to 1970. Since then, some eighty eyewitnesses as far flung as British Columbia and Australia have reported crop circles forming in under twenty seconds; cases are often accompanied by sightings of incandescent or brightly-coloured balls of light, shafts of light or structured flying craft.
