The soil has been collected and the plants tested, but researchers still are in the dark as to what caused the crop formations on a Bainbridge soy bean field. Jeffery Wilson, an independent researcher from Michigan, said he and a group of 20 volunteers spent all Saturday and Sunday studying the circles in hopes of ruling out the possibility of a hoax. He said he has not found evidence to suggest where they came from but the information that has been gathered is interesting and could lead to better understanding the sightings. Wilson said he was able to narrow the creation down to four to five weeks ago and is not surprised they went undetected for such a long time. "The ground is very isolated and you can't see it from any roadway," he said. "We think it would not be the place a hoaxer would go because no one would see it." Wilson said there are several unique characteristic to the Bainbridge circles including their size and design. The swirls inside the circles are swirled counter-clockwise with multiple layers. When flying overhead the distinct shapes of a triangle, peace sign and bull's eye can be seen. "This particular design is very large and detailed" he said. "Almost 280 feet by 280 feet. Just about the size of a football field in length and in width." The most convincing anomalies Wilson said he saw was actual damage to the soy bean plants. "We found evidence of plant damage at the most delicate point of the plant we believe came from direct heat," he said. "And the boundary between the standing plants and laying plants was almost like a cookie-cutter effect with a deep reddish purple color on the standing plants facing the circles."
