The southwest face of the stone bears two cup marks; circular depressions that were carefully carved into the rock face thousands of years ago. The larger of these measures 8 centimetres across and 2 centimetres deep, whilst the smaller spans 5 centimetres with a depth of just 1 centimetre. Intriguingly, the lower cup mark shows faint traces of what appears to be a ring encircling it, a detail that suggests this stone held particular significance for those who created it.

This ancient marker hasn't stood alone through the centuries; it's now been incorporated into a field boundary, blending prehistoric artistry with more recent agricultural practicality. The stone forms part of a wider landscape of rock art in the area, with two other decorated panels located just 9 metres to the northeast and 30 metres to the southwest. These nearby examples help paint a picture of an area that was clearly important to our ancestors, who took the time to mark multiple stones with their distinctive cup and ring designs.

About 160 metres to the northwest stands another ancient stone, adding to the concentration of prehistoric monuments in this corner of Donegal. Together, these features create a ritual landscape that would have held meaning for the communities who lived here during the Bronze Age. The careful positioning of these monuments, their decorated surfaces, and their survival through millennia offer us a tangible connection to Ireland's distant past, preserved in the windswept fields of the county's rural heartland.
