Rather than rising alone in an open field, this squat conglomerate stone sits off-centre within an enclosure, on an east-south-east-facing slope now given over to pasture. Enclosures of this kind, roughly circular earthworks that in an Irish context can indicate anything from a prehistoric ceremonial space to an early medieval farmstead, are common enough in Tipperary. A standing stone placed deliberately inside one, however, is a less ordinary arrangement, and raises questions about how the two were understood in relation to each other.

The stone itself is not imposing. Measuring roughly 1.1 metres by 0.8 metres at the base and standing 1.2 metres tall, it is irregular in plan, oriented on a northeast to southwest axis, and rises to what is described as a flat point. The material is conglomerate, a sedimentary rock made up of rounded fragments cemented together, which gives it a rougher, more varied surface than the smooth limestone uprights seen elsewhere in the region. Cattle have worn a noticeable depression around its northeastern and southeastern base. More intriguing is a piece of local knowledge attached to the site: a second stone was apparently removed from beside the ditch in the field immediately to the west. That loss is unrecorded in any detail, but it shifts how the site reads. Two further standing stones survive in the near vicinity, one approximately 45 metres to the west and another around 260 metres to the southwest, suggesting that this part of Glennaskagh once held a loose cluster of such monuments, most of which no longer stand where they were first placed, if they stand at all.
