Karst is the limestone landscape characteristic of this part of Ireland, shaped by centuries of water dissolving the rock beneath, producing the fissured, pale terrain the Burren is known for. The cairn, a roughly circular mound of heaped stone, measures about 14.3 metres on its longer axis and stands between 1.1 and 2.2 metres high depending on where you measure it. Its upper surface is flat, around 2 metres across, and sits slightly off-centre to the east. Stone has slumped and scattered down the western face over time, and the remains of old field walls, long since collapsed and overgrown, have crept in from the northwest, east, and south, blurring the boundary between the ancient monument and the agricultural landscape that eventually grew up around it.

The antiquarian Thomas Johnson Westropp visited and noted the cairn in 1905, observing several long, flat slabs within the mound and speculating that they might be the remnants of a cist, a stone-lined burial box of the type sometimes found at the core of prehistoric cairns. When the site was examined again in 1998, those slabs were no longer visible, either reburied under shifting rubble or obscured by the accumulating turf. What makes the location particularly striking is its immediate context: within roughly 100 metres of this cairn, there are at least three other prehistoric structures, including two wedge tombs, a form of megalithic monument built during the late Neolithic and early Bronze Age, typically consisting of a roofed gallery that narrows toward one end. A fourth megalithic structure lies approximately 42 metres to the northeast. The ridge, in other words, was not incidentally used; it appears to have been deliberately and repeatedly chosen as a place of significance, its commanding views across the surrounding landscape presumably part of what drew people to it across generations.
