I had already replied to Catherine by email, but just to note, there may be some differences between databases. I would have to compare mine / CCCRN’s with the Cropcircle-Archive, which I am quite familiar with. I have kept the Canadian listings to only formations, of crop circles by the simplest definition, which are either circular or geometric and flattened in vegetation. It doesn’t include other types of “circular phenomena” such as ice rings, circles in soil, circles of dead or burned grass for example, or “randomly downed” formations (non-circular or geometric) in grass or crops. I have separate archives of all of those.
