It is an arrangement that would be easy to walk past without a second thought, and yet the geometry is precise enough to suggest it was once deliberate. One ridge runs roughly north to south, standing about 0.9 metres high and stretching 48 metres in length; the other, lower at 0.35 metres, runs southwest to northeast for just over 72 metres. Together with a 74-metre east-west section of field fence, they close into a triangular enclosure whose original purpose is not recorded.

The earthwork sits in the shadow of Cloghanughera castle, and that proximity is probably the most useful clue to its context. Earthworks of this kind, linear ridges forming enclosures or boundaries near tower houses and castles, often functioned as bawns or outworks, a bawn being a walled or embanked enclosure attached to a castle and used for the protection of livestock or as a defended outer yard. Whether this particular earthwork served such a role, or represents an earlier or later feature of the landscape, is not stated in what survives of the record. What can be said is that the combination of two slightly different orientations and two noticeably different heights suggests the ridges may not have been built at the same time, or may have served different functions within the same broader enclosure.
