Standing 2.6 metres tall and rectangular in cross-section, measuring roughly 1.6 metres by 0.75 metres, it has occupied the northern slope of the Sullane River valley for a very long time indeed, long enough that the packing stones used to stabilise it at the base have become partially exposed, hinting at the deliberate effort that went into its erection.

Standing stones of this kind are a common feature of the Irish prehistoric landscape, though common does not mean well understood. They were raised during the Bronze Age in most cases, though precise dating of individual examples is rarely possible without excavation. Their purposes remain genuinely uncertain: boundary markers, sites of ritual or commemoration, astronomical alignments, or some combination of functions that has simply not survived in any recoverable form. This particular stone is oriented with its long axis running northeast to southwest, a detail that may or may not be meaningful but is the kind of thing that has kept archaeologists cautious about broad interpretations. The packing stones visible at its base are a relatively unusual detail, offering a rare glimpse of the original installation technique, where builders wedged smaller stones around the base to hold the upright steady in the ground.
