Crop circles are unexplained patterns that are found in fields, over tree-tops, and in ice and snow. They are mostly often found in wheat or corn fields, but have also been found in oat, rape (canola), and barley.
They are a world wide phenomena, highlighted in England, the Netherlands, the United States, and Australia. Crop circles have not as yet been reported in China and South Africa.
Their sudden appearance may go unreported unless spotted by an airplane flying overhead or someone familiar with the concept of the formations. I am quite sure that crop formations are as old as the planet itself.
The earliest known formation was in 1647 in England, from which a carving of the current day theory on how it was created can be seen.
The crop circle phenomenon was first reported during modern times in 1972 when two witnesses, Arthur Shuttlewood and Bryce Bond, sat on the slope of Star Hill near Warminster, England, hoping to catch a glimpse of the strange unidentifyed flying craft that had made this part of England a UFO Mecca for almost a decade. But what they witnessed on that moonlit night was something more extraordinary--a hundred feet away they saw an imprint take shape, a large circular area of plants that collapsed within twenty seconds.
Crop formations are often accompanied by sightings of unusual lights and structured craft beaming shafts of light onto the field the night before. Most crop formations are created at night between the hours of 11 PM--4 AM. There have been daylight formations also.
Very often crop formations appear where powerful ley lines intersect-- or the Earth's magnetic energy lines. This is often at the same place where megalithic sites such as Stonehenge are found. Dowsing can be done within the formations after the crop has been plowed when there are no longer traces of physical evidence.
The patterns often can be equated to Creation, Celestial Bodies, the Chakras, or Sacred Geometry.
