The marks are not large or dramatic. The main motif, a cup surrounded by a single ring, measures roughly nine centimetres by twelve; the central cupmark is just four centimetres across and four millimetres deep. And yet there it is, deliberate and legible, at 175 metres above sea level on a gentle slope facing the northeast.

The carving belongs to the broader tradition of prehistoric rock art found widely across Atlantic Europe, most commonly dated to the Neolithic or early Bronze Age, though precise dating remains difficult because the carvings themselves contain no organic material to analyse. Cup-and-ring marks, the most recognisable form, consist of a pecked or picked hollow surrounded by one or more concentric rings; their purpose is not understood, though interpretations have ranged from territorial or astronomical markers to purely ritual objects. At this site, the central motif is accompanied by three additional cupmarks, one of which sits directly on the picked ring itself, and by a scatter of smaller pickmarks across the decorated surface that follow no obvious pattern. The rock is slightly fractured sandstone, and the decorated face looks to the southwest, away from the valley the slope overlooks.

The setting places it in a landscape that has clearly been worked over a long period. A bog trackway runs a few metres to the southeast, old turf banks and cutting areas lie to the south, and a disused reservoir sits roughly forty metres to the northeast. A watercourse draining from Coomnacronia Lake passes about fifty metres to the northwest. The carving sits quietly among all of this, easy to miss, grassed-in and fractured, with the mountains closing in from the south and west.
