Nice #cropmarks! Just south of Edinburgh. This was one of the first places we went looking for cropmarks when I worked with the RCAHMS aerial survey team in the 90s. Very clear triple palisaded enclosure, and two crossing pit alignments. Indicates later prehistoric settlement & land divisions.

Total outsider here, wondering whether clever tech that allows farmers to treat areas of fields differently according to need may end up making these marks harder to see? (If you see what I mean)

The visibility of cropmarks depends on a subtle combination of weather (moisture levels) & the crop type (as well as other variables). So if a farmer plants potatoes, forget it. Or if it rains a lot in May, it’s probably not going to happen. And deep ploughing will destroy the buried archaeology.
