My brother follows this guy who does videos on wild camping and bushcraft. In today's segment a friend asked him to come fly his drone over his fields as he thought with the dryness and heat some parchmarks (or crop marks) would be visible. It's just 13 minutes long but I found it quite interesting. I love that area of England!

I expect some more newly discovered parchmarks will be cropping up, lol!!
