It is neither. The mound is a cairn, a deliberate accumulation of stones heaped by human hands, roughly circular in plan and measuring around six metres east to west, five metres north to south, and only about forty centimetres above the surrounding sod. Stones of varying sizes make up its body, with others visible at intervals along the perimeter where the turf has worn away or never fully taken hold. From this vantage point, the view opens out to the north-west, across the valley of the Ouvane River, and it is hard not to wonder whether that prospect was incidental or entirely the point.
