Rising to around 2.5 metres and spreading roughly 18 metres across its base, it has every appearance of a prehistoric burial cairn, a mounded stone monument of the kind raised over the dead during the Bronze Age or earlier. But the possibility lingers that it was simply a clearance cairn, the accumulated result of farmers dragging stones off workable land, or a boundary marker with no funerary purpose at all. The ambiguity is part of what makes it interesting.

What complicates the picture further is a small circular cavity, about 1.2 metres across and 0.6 metres deep, set slightly off-centre toward the southern side of the mound. This may have been a booley shelter, a temporary structure used by herders during transhumance, the seasonal movement of livestock to upland grazing. There are hints of other similar chambers within the cairn, and what looks like the ghost of an L-shaped passage, though stone collapse has obscured most of it. Around the cairn, the landscape holds further traces of early activity: a dry-stone wall running east to west marks the townland boundary with Glenteige about 10 metres to the south, and two other meandering walls to the north may be the remnants of a prehistoric field system. An Ordnance Survey trigonometrical station, marking a spot height of 894 feet, sits about 35 metres to the north-north-west, and a hilltop enclosure lies 80 metres to the north.

The cairn sits at the kind of elevation where the surrounding countryside opens up considerably, which would have made the location conspicuous and meaningful in any era. Whether the monument was raised by people who wanted to be seen, or simply by people clearing ground, the stone has stayed put long enough to outlast any certainty about why it was placed there.
