Any #bronzeage experts out there? I'm interested in the linear feature in the foreground across the hillside here near Bethesda, north Wales. It's not recorded on the historic environment databases. In an area with plenty of slate trials, this doesn't fit that possibility, not least as its in grits territory, not slate.

The cairns around are Bronze Age and part of a wider funerary landscape.

So, what's that trench or wall?
