The crop-circle archive that folds 7,551 formations into one record each
A searchable public record of reported crop formations, spanning 1590–2026 with locations, dates, images, measurements, shapes, and source trails.
Field notes
The site combines records from three long-running crop-formation archives, normalizing differing names and dates into one entry per formation. Its data model includes derived coordinates, recorded diameters where a source provides them, source-page links, and image or drawing status. The homepage reports 7,551 formations across 65 countries and uses seasonal visualizations to show both reporting patterns and archive coverage, cautioning that year-by-year curves reflect who was publishing and when rather than a complete count of formations.
