First Significant UK formation of 2004 spotted On May 3, near Deacon Hill in Bedfordshire, UK, the first significant formation of the year has been spotted in a flowering field of oil seed rape. The formation is similar in design to the 2003 Locust Grove, Ohio formation that appeared close to the Serpent Mound earthwork. Although it has been raining rather steadily, since being spotted, the formation has been inspected, and there have been some details that have emerged which may indicate the formation may be not have been a human mechanically-made one.
