Aerial view of a crop formation at Cheesefoot,Hampshire,England. Crop formations are patterns of flattened plants in crops such as wheat or barley. They started appearing frequently in the mid-1980s in south-west England. Their cause is unknown. Many theories exist,ranging from science-based physical explanations such as the "plasma vortex" theory based on the phenomenon of electrohydrodynamics (EHD) to unorthodox suggestions that they are created by extraterrestrial intelligences.
