I have come across a few ironage/bronze age round ditches which seemed to have been crossed out by Roman ditches but I must admit that the appearance of hedges in 1945 crossing bizarre circular running ditches is a whole new subject to me. It sounds like you have rings on top of rings, I think that there was an Olympics in Britain in 1948 which might work with your description but I suspect that the cropmarks in google earth have the same origin as my long linears. Do you find that they cause you to squint?
Reason: your past is my past
