Cup marks are among the most common forms of prehistoric rock art found in Ireland, small circular depressions ground or pecked into stone, yet their purpose remains genuinely unclear. What makes this particular boulder quietly odd is the way its decoration tells the story of its own former burial: one end of the upper surface is entirely plain, and the most plausible explanation is that this blank section never broke the ground surface in prehistory, leaving the carver to work only on what they could actually see and reach.

The boulder, which measures roughly 1.9 metres by 1.6 metres across and stands 1.3 metres high, was almost certainly moved to its present position during relatively recent agricultural improvement of the surrounding fields, most likely shifted from further up the slope to the north. It sits on the south-facing side of a ridge, with a view eastward toward the Ballyduff Pass, though mature trees around the farmhouse now close off what would once have been an open prospect toward the mountains to the south and southwest. The decorated portion covers about two-thirds of the upper surface and is notably dense, the cups averaging three to four centimetres across, many arranged in pairs and a few conjoined. There are no clear traces of enclosing rings around any of the cups, which is not unusual for Irish prehistoric rock art but is worth noting given how crowded the surface is. At one corner, a triangular formation of quartz veins catches the eye, and within that natural triangle there appear to be five additional cup marks and a short groove. Roughly in the centre of the decorated area is a shallow borehole, likely the remains of a failed modern attempt to split the stone for building or field-clearing purposes, a reminder that the boulder has had a complicated afterlife as well as a long prehistory.
