It was hard to tell what this is due to the livestock time limitations I had here. The large capstone says a portal tomb, but this stone could be a roofstone from a wedge tomb. As the tomb is in court-cairn country, it just might be so, but there's no evidence of a court.
The mound that the burial chamber is in is completely overgrown. It stretches back from the chamber by about 20 metres and contains cairn material at the flatter back end. There are kerb-like stones on its eastern side, so are we talking a passage grave?
