Crop Circles” is a name coined by Colin Andrews for the unusual geometric formations that have been discovered in various crops since the 1960’s, although there is some historic evidence via woodcuts and the like that dates them back to the 1600’s. Most researchers agree that the modern crop circle sensation began in 1966 with the Tully event in Australia, when a farmer named George Pedley heard a sound and saw a UFO rising from a swamp. He then found a circle of pressed reeds that was photographed and documented. Subsequently, other circles started to be discovered. Throughout the 1960’s and 70’s the formations consisted of mainly circles and rings.
