It is neither. The surviving section stretches roughly sixty metres, rises to about 1.1 metres in height, and is stone-faced in parts, with a fosse, a defensive ditch, roughly half a metre deep, still visible along its southern side. A counterscarp bank, the smaller secondary ridge thrown up on the far side of the ditch, adds to the impression of something deliberately engineered rather than incidentally accumulated.

The structure appears to be a fragment of a much longer boundary feature sometimes called the 'auld ditch', a vernacular name that carries its own quiet antiquity. Around 800 metres further west along the same county boundary, a related feature was recorded by someone identified as Bateman between 1716 and 1717, suggesting that what survives near the road is only one visible remnant of a more extensive line. A boundary stone still stands at the eastern end of the Breeda section. The bank seems to continue on the western side of the road as well, though overgrowth has made that portion impossible to examine closely. Whether the full line was originally a territorial marker, a jurisdictional boundary, or something older still is not settled, but its alignment with the modern county border hints at a division of the landscape with very deep roots.
