NT0748 : Cultivation Terraces
Are these documented as ''Cultivation terraces"?
It looks more like Medieaval rig and furrow ploughing to me.
Here's an example near the East Coast, but not so well defined, probably this field has been ploughed several times in a more conventional way but the ridges are still evident - and they seem especially pronounced with thawing snow highlighting the dips between each rig.
