The bog itself has been worked, its upper layers removed over time to harvest fuel, and in doing so it has exposed what may be the remnants of an old field wall, a boundary that once divided or enclosed ground now given over entirely to bog. The stones are gapped and set in a single row, the kind of modest, functional construction that rarely attracts attention but speaks quietly to a landscape that was once managed, farmed, and lived in.

The wall can be traced for roughly nine metres along a north-north-east to south-south-west axis, with a shorter section of about three and a half metres extending southward from the lower end. The stones of the longer stretch are relatively close-set and still reasonably proud of the ground, reaching up to about 45 centimetres in height, with individual stones measuring between 40 and 80 centimetres across. The shorter section is far less visible, its stones barely breaking the bog surface, as though that end of the structure was either built with smaller material or has simply settled more deeply into the peat over the years. Cutaway blanket bog, which forms in wet, waterlogged conditions over centuries of accumulated organic matter, tends to preserve what lies beneath it rather than destroy it, so the survival of even this much is less surprising than the fact that the cutting away of the bog has brought it back into view at all. Pasture fields border the site to the south-west and north, suggesting that this corner of Sligo was once more extensively worked than its current appearance implies.
