The wall they form is low and intermittent, its tops protruding from the peat rather than rising above it, tracing a course of roughly 75 metres in a north-east to south-west direction across rough, undulating hill pasture. At only 0.4 metres thick and 0.3 metres high where it can be measured at all, this is not a wall anyone would notice from a distance. It is the kind of feature that rewards attention rather than commands it.

What makes it archaeologically interesting is precisely what makes it physically faint. The boundary is a relict, meaning it belongs to an earlier landscape that the bog has since consumed or partially obscured. Blanket and cutaway bog, the latter being ground from which peat has already been cut and removed, now covers much of the area around Rodeen, and the stone wall was swallowed along with the fields it once divided. Shorter stretches of walling to the west and south-west suggest this was not a single isolated boundary but part of a more extensive system of enclosure, the rest of which has either disappeared beneath the peat or been lost to limited field clearance that removed some of the stones entirely. The original purpose and date of the boundary are not recorded, but field systems of this kind, buried beneath Irish bogland, can sometimes represent agricultural activity from the Bronze Age or earlier, when the land was more open and workable before the bog expanded.
