Crop marks?

Hi all

I have only ever seen aerial photos of crop marks on the web, never one close up in person. Anyone have any experience of them and what they look like?

It's been very dry around here of late and I was recently walking through a field with known hut circles in the next field along. The grass is pretty dry looking at the moment and I noticed a green circular outline on a slight raise in the field. It's roughly the same size as the nearby hut circles and even had a break in the circle in approx position similar to the entrance to the hut circle nearby. Nothing mentioned on Canmore.

A few photos and a short video

It would be good to know anyone's thoughts? I have no knowledge of these things so please feel free to say I'm just wishful thinking :-)

I imagine this current dry spell means it'll be a bumper year for crop marks, looking forward to whatever gets photographed being brought to the wider public's attention. As to your ring, well there deffo looks to be something under the surface (drip gully if it is your roundhouse? maybe a stock pen associated with the other settlement?). Don't forget, many fungi, and their underground mycelium can leave these kind of marks too. If you have a nose at Google Maps satellite view, on much grassland, esp in hilly regions you'll see 'faery rings' all over the place, some are enormous.

A Scottish lass, Kirsty Millican who wrote a thesis on the subject....

When we lived in Chelmsford, I remember looking out on the green in front of the house and seeing circles of a darker green grass, and we were'nt too far away from a neolithic cursus, it is just there like turning the pages of a history book.

There's a programme on C4 tomorrow (Sun) called Hidden Britain by Drone which may be interesting
