The stone, measuring roughly 1.2 metres by just over a metre, bears five shallow cup-marks and a groove carved into its upper surface. Cup-marks are among the most common yet least understood forms of prehistoric rock art found across Ireland and Britain, simple circular depressions ground into stone that may have carried ritual, territorial, or astronomical meaning, though no consensus has ever settled the question. What makes this particular example quietly strange is not the carvings themselves but where the stone ended up.

At some point in the early 1980s, the boulder was lifted from the field where it had presumably rested since prehistory and dumped onto a radial-stone cairn nearby. A radial-stone cairn is a type of Bronze Age burial monument in which stones are arranged in lines radiating outward from a central point, and the one in question is a recorded archaeological site in its own right. Whoever moved the boulder, whether to clear the land for farming or simply to be rid of an inconvenience, placed a carved prehistoric stone on top of a separate prehistoric monument, creating an accidental layering of two unrelated antiquities. The act was practical rather than ceremonious, but the result is a small archaeological tangle that preserves the cup-marked stone while complicating any reading of both features.
