The stone itself is a substantial presence: a limestone upright measuring 2.35 metres high, 1.1 metres wide, and 0.6 metres thick, tapering as it rises and aligned along a north-south axis. Its surfaces are described as fairly smooth, which is notable for a limestone monument left to the elements on a low rise in open pasture.

The name Clogh Stuckagh appears on the Ordnance Survey six-inch map of 1837 and again on the revised twenty-five-inch edition of 1913, indicating that the monument had a recognised local identity well before any formal archaeological interest. The Irish word "cloch" simply means stone, and the full name likely preserves an older local designation, though its precise meaning is not recorded. What makes the site additionally interesting is the presence of a souterrain approximately forty metres to the south. A souterrain is an underground stone-lined passage or chamber, typically associated with early medieval settlement and used for storage or refuge. The proximity of these two monuments raises the possibility that the standing stone and the souterrain belong to a broader pattern of activity in this part of Snimnagorta, though no excavation appears to have established a direct relationship between them.
