Roughly five metres across and just over a metre high, it is constructed of stones beneath an earthen covering, and it may or may not be a cairn, the word used cautiously here in the archaeological sense: a deliberate pile of stones, often associated with burial or memorial practice in prehistoric Ireland.

What makes this particular mound quietly interesting is the accumulation of detail around its edges. Crude limestone blocks, measuring roughly thirty to fifty centimetres, are arranged around its perimeter, most noticeably in the north-eastern quadrant, in a pattern that suggests kerbing, the ring of upright or laid stones that typically defines the outer boundary of a constructed cairn. A few of these blocks protrude from the mound itself. At the south-south-eastern edge, a cluster of smaller stones may represent the collapsed remains of walling, though the record is careful not to be definitive on this point. The mound is built directly into the slope rather than sitting free on open ground, which adds a further layer of ambiguity to its interpretation. Around sixty metres to the north-west lies a D-shaped enclosure, a form sometimes associated with early medieval settlement or enclosure activity, and Lough Muck sits just twenty metres to the west, close enough that the embankment and whatever was built on it would have had a clear relationship with the water's edge.
