The decorated surface measures little more than a metre across in either direction, and most of it is still buried. What remains visible is quietly precise: a series of cup-and-ring motifs, the kind of prehistoric abstract carving found across Atlantic Europe, in which a shallow circular depression, the cup, is surrounded by one or more incised concentric rings. Nobody knows with certainty what they meant to the people who made them, or exactly when, though the tradition is broadly associated with the Neolithic and Bronze Age periods.

The sandstone face here carries three distinct motifs, all worked by pickmarks along its southern margin. At the western end, a single cup sits within a partial ring that curves from south-west through west to north-east, interrupted by two natural fractures in the rock. Towards the centre of the decorated area, a cup is enclosed by two rings, though the outer ring is open to the east, possibly because repeated freeze-thaw action over millennia has broken away that section of stone. A radial groove, a line cut outward from the cup, extends eastward and runs beyond the edge of the motif itself. The third motif, at the eastern end of the decorated surface, also has two rings and its own short radial groove extending to the south-east. Around this third carving, a line of pickmarks traces the outer ring and terminates in a tight circular cluster to the north, which may represent an unfinished or intended cup. About 25 metres to the south lies a second rock art site with noticeably similar characteristics, close enough and comparable enough that the two may in fact record the same outcrop approached from different directions or surveyed at different times.
