Each year more than 100 formations appear in the fields of southern England. About 10,000 crop circles have been documented worldwide since records began to be kept in the '70s. Not including this year's formations, England tops the list with around 1,784, followed by the U.S. with 228, Canada with 135, Germany with 105, Australia with 71, the Netherlands with 62, Hungary with 23 and Japan with 19, most of them appearing in rice paddies. Dozens of other countries on every continent have also reported small numbers of simple formations.

Wiltshire County, UK is the acknowledged center of the phenomenon. The county is home to some of the most sacred Neolithic sites in Europe, built as far back as 4,600 years ago, including Stonehenge, Avebury, Silbury Hill, and burial grounds such as West Kennet Long Barrow. Some pretend that crop circles are usually aligned with ley lines, so you may discover new crop circles by following the lines.
