Can anyone give examples of really intricate ones from the 1970s or around that era?
To me it seems the really great looking ones have been appearing more frequently, and getting better and better since the 90s.

All the older images I have seen have just been pretty regular shapes, nothing overly complex. This includes the really old ones like the "mowing
If it's aliens involved, then because they have the ability to travel huge distances in space, I would expect them to have had the technology to
create really complex circles all that time, right back to "mowing devil", and the 70s.
So my theory is that if any of these crop circles are alien made, it is the very plain ones, as they are the ones that have been consistent for
decades and longer to my knowledge.
